DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS
[0009]
First Embodiment
In a casino such as a casino, highly stacked chips are
placed on a gaming table, and thus, there is a problem in that
a total amount of the chips cannot be accurately read by an IC
tag reading device provided under the gaming table. If the
sensitivity of the reading device is heightened, chips placed
at other positions (win or lose depends on the position) may
be added, and thus, there is a problem in that the total amount
of chips at each position cannot be recognized. In addition,
in image capturing of a camera, there is a problem in that the
total amount of chips cannot be recognized because a blind spot
is formed according to a viewing angle of the camera, or entering
into a shadow caused by overlap.
7
CA 03032770 2019-02-01
[0010]
In addition, if cards are slanted by "card squeegee"
(behavior of bending a face-down card to enjoying a rank of the
card little by little) or the like which is frequently performed
by players in a baccarat game, there is a problem in that ranks
and suits of cards cannot be determined through image analysis
using cameras.
[0011]
In addition, fraud in the gaming table is further more
sophisticated, and thus, there is a new problem in that fraud
by an advanced betting method which cannot be found through
simple detection of largeness or the like in the winning amount
in the gaming table cannot be detected by the camera or by
tracking the winning amount. In addition, fraud according to
conspiracy of a dealer and a player is not sufficiently
prevented in the related art.
[0012]
In order to solve the above-described problems, in a first
embodiment, a fraud detection system in a casino having a
plurality of gaming tables is configured to include a game
recording apparatus which records a progress of a game played
in the gaming table including a dealer and a player as an image
through a camera, an image analyzing apparatus which performs
image analysis on the image of the recorded progress of the game,
a card distribution device which determines a win or lose result
of each game in the gaming table, and a control device which
detects fraud practiced in the gaming table by using a result
8
CA 03032770 2019-02-01
of the image analysis by the image analyzing apparatus and a
win or lose result determined by the card distribution device.
[0013]
In addition, in the fraud detection system, the card
distribution device has a structure capable of reading ranks
of the cards distributed. The control device has a structure
capable of determining match or mismatch by checking
information on the rank obtained from the image of each card
distributed in the gaming table by the image analyzing apparatus
and information on the rank of the card read by the card
distribution device.
[0014]
In addition, in the fraud detection system, the image
analyzing apparatus or the control device has an artificial
intelligence utilizing type structure or a deep learning
structure capable of obtaining information on rank of a card
from the card which is distributed in the gaming table and is
folded or stained by a player.
[0015]
In addition, in the fraud detection system, the control
device recognizes positions, types, and numbers of chips
wagered by players through the image analyzing apparatus and
determines by image analysis of a progress of the game through
the image analyzing apparatus whether or not the collection of
the lost chips wagered by each player and the redemption for
the winning chips are correctly performed in accordance with
a win or lose result of the game.
9
CA 03032770 2019-02-01
[0016]
In addition, in the fraud detection system, the image
analyzing apparatus or the control device has an artificial
intelligence utilizing type structure or a deep learning
structure where, although a portion of or the entire chips among
a plurality of the chips placed on the gaming table is concealed
due to a blind spot of the camera, the information on the type,
number, and position of the wagered chips can be obtained.
[0017]
In addition, in the fraud detection system, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure where comparison calculation
according to the win or lose result of the game can be performed
on whether or not the recognized amount of the chips in the chip
tray of the dealer of the gaming table is increased/decreased
according to the collected amount of the lost chips wagered by
each player and the paid amount of the winning chips after the
end of the game and the settlement.
[0018]
In addition, in the fraud detection system, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure capable of recognizing the position
and amount of the chips wagered in each play position of the
game table and comparing the history of win and lose of each
player obtained from the win or lose result of each game and
the amount of the acquired chips and the statistical data of
previous games to extract a strange situation.
CA 03032770 2019-02-01
[0019]
In addition, in the fraud detection system, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure capable of comparing a state that,
at a play position of a certain gaming table, the amount of
betting chips at the lost time is smaller than the amount of
betting chips at the win time and the statistical data of
previous games to extract a strange situation.
[0020]
In addition, in the fraud detection system, the control
device has a structure capable of extracting the strange
situation through the image analyzing apparatus or specifying
individual players at the player positions where winning of a
predetermined amount or more occurs.
[0021]
In addition, in the fraud detection system, the control
device has a caution function of informing about the existence
of the specified player in another gaming table when the
specified player departs and arrives at the other gaming table.
[0022]
In order to solve the above-described problems, according
the invention, there is provided a fraud detection system in
a casino having a plurality of gaming tables is configured to
include a game recording apparatus which records a progress of
a game played in the gaming table including a dealer and a player
as an image through a camera, a card distribution device which
determines a win or lose result of each game in the gaming table,
11
CA 03032770 2019-02-01
an image analyzing apparatus which performs image analysis on
the image of the recorded progress of the game, and a control
device which can detect cash and chips in the game table by using
a result of the image analysis by the image analyzing apparatus.
The image analyzing apparatus or the control device has an
artificial intelligence utilizing type structure or a deep
learning structure capable of detecting the exchange of cash
and chips in the gaming table in a situation other than the state
that the dealer is dealing based on information from the card
distribution device or the dealer, capable of recognizing the
total amount of the cash which is genuine cash verified by black
light and recognizing the total amount of the chips even in the
state that a portion of or entire one chip among a plurality
of the chips placed on the gaming table as an exchange object
is concealed due to a blind spot of the camera, and capable of
comparing the total amount of cash placed on the gaming table
by the player and the total amount of chips placed by the dealer
to determine whether or not the two amounts match with each
other.
[0023]
In addition, in the fraud detection system, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure capable of performing comparison
calculation as to whether or not the recognized amount of chips
in a chip tray of a dealer of the gaming table is increased or
decreased according to a paid amount of the chips corresponding
to the exchanged cash after exchange of cash and chips for
12
CA 03032770 2019-02-01
settlement.
[0024]
In addition, in the fraud detection system, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure where, after the exchange of the
cash and the chips for settlement, comparison calculation of
match or mismatch between the input amount of the cash according
to the input by the dealer and the total amount of the cash
according to the result of the image analysis by the image
analyzing apparatus can be performed. In addition, the control
device has an artificial intelligence utilizing type structure
or a deep learning structure capable of performing comparison
calculation of match or mismatch between the total input amount
of the cash according to the input by the dealer in the gaming
table for which the dealer is responsible and the total amount
of the cash according to the result of the image analysis by
the image analyzing apparatus.
[0025]
According to the fraud detection system of the embodiment,
although the cards are slanted by "card squeegee" frequently
performed by players in a baccarat game or the like, the rank
and suit of the cards can be determined by image analysis, so
that the total amount of chips being overlapped or being in a
blind spot together with the positions can be recognized. In
addition, fraud at the time of exchanging cash and chips can
be detected.
[0026]
13
CA 03032770 2019-02-01
Hereinafter, an overview of the fraud detection system
in the casino having a plurality of the gaming tables in the
first embodiment will be described more in detail. FIG. 1 is
a diagram illustrating the overview of the system. The fraud
detection system in a casino having a plurality of gaming tables
4 is configured to include a game recording apparatus 11 which
records a progress of a game played in the gaming table 4
including a player (game participant) 6 and a dealer 5 as an
image through a plurality of cameras 2, an image analyzing
apparatus 12 which performs image analysis on the recorded image
of the progress of the game, and a card distribution device 3
which has a function of determining a win or lose result of each
game in the gaming table 4 and displaying the win or lose result.
The card distribution device 3 is a so-called electronic shoe
used by the skilled in the art and has a structure where a game
rule is programmed in advance and win or lose of the game can
be determined by reading information of the cards C distributed.
For example, in a baccarat game, banker win, player win, or tie
is basically determined by a rank of two or three cards, and
a determination result (win or lose result) is displayed by a
result display lamp 13.
[0027]
The fraud detection system is configured to further
include a control device 14 which compares the actual rank of
the cards according to the result of the image analysis by the
image analyzing apparatus 12 and the win or lose result
determined by the card distribution device 3 to detect fraud
14
CA 03032770 2019-02-01
(for example, mismatch between a sum of ranks of distributed
cards and a win or lose result) performed in the gaming table
4. The card distribution device 3 has a structure capable of
reading rank (A, 2 to 10, J, Q, K) and suit (heart, spade, or
the like) of the card C manually distributed by the dealer 5.
The control device 14 has a structure capable of determining
match or mismatch by checking information on rank and suit
obtained from the image (captured by using the camera 2) of each
card distributed in the gaming table 4 by the image analyzing
apparatus 12 (using artificial intelligence) and information
on rank and suit read by the card distribution device 3. In
this fraud detection system, each of the image analyzing
apparatus 12 and the control device 14 has a structure including
a computer configured with an integrated or plural components,
a program, and a memory in a complex manner.
[0028]
Each of the image analyzing apparatus 12 and the control
device 14 has an artificial intelligence utilizing type
structure or a deep learning structure where, with respect to
even a card C which is distributed in the gaming table 4 and
is folded or stained by the player 6, information on rank of
the card can be obtained. As illustrated in FIG. 4, there occurs
a situation where the stained card C is difficult to distinguish
clover from spade it. Even in this case, suit determination
can be performed by image analysis and determination using an
aartificial intelligence utilizing type computer or control
system and a deep learning (structure) technique. In addition,
CA 03032770 2019-02-01
although the cards are slanted by "card squeegee" frequently
performed by players in a baccarat game or the like, the suits
or ranks of the cards before deformation can be recognized by
using self-learning or the like of a large number of images in
a modified example by artificial intelligence utilizing type
computer or control system and a deep learning (structure)
technique. Since the artificial intelligence utilizing type
computer or control system and a deep learning (structure)
technique are well-known and available by the skilled in the
art, the description thereof is omitted.
[0029]
The control device 14 having an artificial intelligence
utilizing type structure or a deep learning structure can
recognize, through the camera 2 and the image analyzing
apparatus 12, the position (player, banker, or pair) of the
betting area 8 on which the player 6 wagers the chip 9 and the
types (different amount values are designated to different
colors of the chips 9) and the number of the wagered chips 9.
In many case, the chips 9 are not aligned and stacked in the
vertical direction, but as illustrated in FIG. 2A, the chips
are deviated and overlapped. In this case, it is assumed that,
when the camera 2 is disposed in a direction of an arrow X
illustrated in FIG. 2A (or when the direction of the chip 9
becomes a blind spot direction relatively), as illustrated in
FIG. 2B, the chip 9 is not seen (in a blind spot). In an
artificial intelligence utilizing type computer or control
system and a deep learning (structure) technique, by using a
16
CA 03032770 2019-02-01
self-learning function or the like, concealing or the like
(including concealing of a portion of one chip and concealing
of the entire chip) of the chip 9 caused by the blind spot is
recognized, so that the number of chips or the like can be
accurately recognized. In this manner, since which position
(player, banker, or pair) of the betting area 8 the chips 9 are
wagered on, types of wagered chips 9 (different amount values
are designated to different colors of the chips 9), and the
number of chips can be recognized, the control device 14
determines by image analysis of a progress of the game through
the image analyzing apparatus 12 whether or not collection
(indicated by an arrow L) of lost chips wagered by the players
6 and redemption (9W) for wined chips to the winning player 6W
are correctly performed in accordance with a win or lose result
of the game determined by the card distribution device 3 for
each game.
[0030]
The control device 14 is capable of performing analysis
and recognition of the total amount of the chips 9 in the chip
tray 17 of the dealer 5 of the gaming table 4 by using the image
analyzing apparatus 12 and is capable of performing comparison
calculation according to the win or lose result of the game as
to whether or not the total amount of the chips 9 in the chip
tray 17 is increased or decreased according to the amount of
the collection of the lost chips 9 wagered by the players 6 and
the redemption (9W) of the winning chips of the winning player
6W after the end of the game and the settlement. Although the
17
CA 03032770 2019-02-01
total amount of the chips 9 in the chip tray 17 are always checked
by means of RFID or the like, whether or not the increased or
decreased amount is correct is performed by the control device
14 allowing the image analyzing apparatus 12 to perform image
analysis of the progress of the game. An artificial
intelligence utilizing type structure or a deep learning
structure is used for these configurations.
[0031]
In this example, since fraud or error is detected based
on the information of the win or lose result of the game,
information as to what position (player, banker, or pair) of
the betting area 8 how many and what type of the chips 9 are
wagered on, and the increased/decreased amount of the chips 9
in the chip tray 17 after the collection of the lost chips and
the redemption for the winning chips 9, fraud or error can be
detected although the recognition of the movement of the chips
9 after the end of the game, that is, the movement of the wagered
chips 9 toward the player side or the movement toward the dealer
side is not performed.
[0032]
Herein, for example, in the baccarat, the win or lose
result of the game can be determined in accordance with the rule
of the baccarat by reading the rank of a card C fed out in the
game in the card distribution device 3. In addition, the win
or lose result of the game can be determined by capturing an
image of the gaming table 4 by using the camera 2, analyzing
the image by using the image analyzing apparatus 12, and
18
CA 03032770 2019-02-01
matching the analysis result with the game rule by using the
control device 14. In this case, the camera 2, the image
analyzing apparatus 12, and the control device 14 constitute
a win/lose result determining apparatus. Information on the
players at each play position 7 and information as to what
position (player, banker, or pair) of the betting area 8 how
many and what type of the chips 9 are wagered on can be obtained
by capturing an image of the chips 9 placed on the betting area
8 by using the camera 2 and analyzing the image at each play
position 7 by using the image analyzing apparatus 12.
[0033]
In addition, the increased/decreased amount of the chips
9 in the chip tray 17 before and after the collection of the
lost chips 9 and the redemption for the winning chips 9 can be
calculated by comparing total amount of the chips 9 in the chip
tray 17 before the collection of the lost chips 9 and the
redemption for the winning chips 9 and the total amount of the
chips 9 in the chip tray 17 after the collection of the lost
chips 9 and the redemption for the winning chips 9. The total
amount of the chips 9 in the chip tray 17 before the collection
of the lost chips 9 and the redemption for the winning chips
9 and the total amount of the chips 9 in the chip tray 17 after
the collection of the lost chips 9 and the redemption for the
winning chips 9 can be detected by capturing an image of the
chip tray 17 containing the chips 9 by using the camera 2 and
analyzing the image by using the image analyzing apparatus 12.
In addition, the total amount of the chips 9 contained in the
19
CA 03032770 2019-02-01
chip tray 17 may be detected by burying RFIDs representing the
amount is in the chips 9 and providing an RFID reader to the
chip tray 17.
[0034]
For example, the total amount of the chips 9 in the chip
tray 17 before the start of the game is denoted by Bb, and the
total amount of the chips 9 in the chip tray 17 after the end
of the game and the end of the collection of the lost chips and
the redemption of the winning chip is denoted by Ba. In addition,
in the game, the total amount of the entire play positions 7
in the player area where the chips 9 are wagered is denoted by
bp, the total amount of the entire play positions 7 in the banker
area where the chips 9 are wagered is denoted by bb, and the
total amount of the entire play positions 7 in the tie area where
the chips 9 are wagered is denoted by bt. For example, in the
case where the win or lose result of the game is banker win,
Ba-Bb = bp - bb + bt needs to be satisfied. Alternatively, the
total amount Ba of the chips 9 in the chip tray 17 after the
end of the game needs to be (Bb + bp - bb + bt) . In the case
where the above condition is not satisfied, it may be determined
that fraud or mistake occurs in the collection of the chips or
the redemption for the chips.
[0035]
FIG. 3A is a diagram illustrating details of the chip tray
in the embodiment, and FIG. 3B is a diagram illustrating another
example of the chip tray. The chip tray 17 is provided with
a collection chip tray 171 where the chips 9L wagered by the
CA 03032770 2019-02-01
lost player 6L are collected and temporarily stored and a
redemption chip tray 172 where to-be-redeemed chips 9W are
stored. The image analyzing apparatus 12 and the control device
14 checks the position, type, and number of the chips 9L wagered
by the lost player 6L and calculate the increased amount of the
chips OL in the game (correct amount of the chips 9 in the
collection chip tray 171). In addition, the image analyzing
apparatus 12 and the control device 14 checks the actual total
amount of the chips 9 in the chip tray 171 after the collection
and compares the correct total amount and the actual total
amount to determine whether or not there is difference.
[0036]
In addition, the redemption for the chip 9W to the wining
player 6W is performed by using the chips 9 in the redemption
chip tray 172, and the image analyzing apparatus 12 and the
control device 14 can secure an enough time to recognize the
actual total amount of the chips 9 in the collection chip tray
171 after the collection.
[0037]
The gaming table 4 is provided with a discard area 41
and/or a discard slot 42 for discarding the cards C used in the
game. When the game is ended, the cards C used in the game are
collected and discarded in the discard area 41 or the discard
slot 42 on the gaming table 4.
[0038]
The gaming table 4 is further provided with a marker 43
indicating win or lose of the game. FIG. 4A is a plan diagram
21
CA 03032770 2019-02-01
illustrating a front side of the marker, and FIG. 4B is a plan
diagram illustrating a back side of the marker. In a baccarat
game, used are two types of markers, that is, a marker 43a
indicating win of a player and a marker 43b indicating win of
the banker. When a result of the game is decided, the dealer
faces down the marker of the winning side of the player and
the banker. Therefore, the win or lose of the game can be easily
found on the table. After the end of the collection of the chips
9 and the redemption, the faced-down maker is returned to the
initial state by the dealer 5. If the maker is returned to the
initial state, the state denotes that the next game can be
started.
[0039]
In this manner, in the embodiment, the control device 14
calculates balance in chips from the amount of the betting chips
on the gaming table 4 for each game and the win or lose result
of the game and verifies the increased amount of the balance
of the chips in the chip tray 17 after the game. If the
difference is detected in the verification, the control device
14 issues caution or adds the record indicating this message
to the record of the video captured by the camera 2. A casino
manager can investigate the cause of the difference by checking
the video.
[0040]
In the embodiment, the fraud detection system performs
addition/subtraction calculation of the increased/decreased
amount of the chips in the game calculated from the position,
22
CA 03032770 2019-02-01
type, and number of the chips 9 wagered by all the players 6
in the game and the win or lose result of the game obtained from
the win/lose result determining apparatus from the total amount
of the chips 9 in the chip tray 17 before the settlement of each
game and compares the correct total amount of the chips 9 in
the chip tray 17 after the end of the game and the settlement
and the actual total amount of the chips 9 in the chip tray 17
at the time of the end of the game obtained through the image
analyzing apparatus 12 to determine whether or not there is
difference between the correct total amount and the actual total
amount.
[0041]
The control device 14 recognizes the position, type, and
number of the chips wagered by each player through the image
analyzing apparatus 12, recognizes the actual total amount of
the chips in the chip tray at the time when the collection of
all the amount of the lost chips wagered by each player is ended,
compares the correct total amount of the chips 9 in the chip
tray 17 added with the increased amount of the chips in the chip
tray 17 in the game from the position, type, and number of the
chips wagered by the lost player from the total amount of the
chips in the chip tray before the settlement of each game and
the actual total amount of the chips 9 in the chip tray 17 to
determine whether or not there is difference between the correct
total amount and the actual total amount.
[0042]
In the case where the control device 14 compares the
23
CA 03032770 2019-02-01
correct total amount of the chips 9 in the chip tray 17 added
with the increased amount of the chips in the chip tray 17 in
the game from the position, type, and number of the chips 9
wagered by the lost player from the total amount of the chips
9 in the chip tray 17 before the settlement of each game and
the actual total amount of the chips 9 in the chip tray 17 and
determines that there is no difference between the correct total
amount and the actual total amount and the control device
compares the correct total amount of the chips in the chip tray
17 after the end of the game and the settlement and the actual
total amount of the chips 9 in the chip tray 17 obtained through
the image analyzing apparatus 12 at the time of the end of the
game and determines that there is difference between the correct
total amount and the actual total amount, the control device
determines a mistake in payment and generates a payment mistake
signal indicating the mistake in payment.
[0043]
The chip tray 17 is provided with a collection chip tray
171 where the chips 9 wagered by the lost player are collected
and temporarily stored. The image analyzing apparatus 12
compares the correct total amount of the chips 9 in the
collection chip tray 171 added with the increased amount of the
chips 9 in the game calculated from the position, type, and
number of the chips 9L wagered by the lost player and the actual
total amount of the chips 9 in the collection chip tray 171 to
determine whether or not there is difference between the correct
total amount and the actual total amount.
24
CA 03032770 2019-02-01
[0044]
When the control device 14 determines that there is
difference that the recognized actual total amount of the chips
9 in the chip tray 17 of the dealer 5 of the gaming table 4 does
not match with the increased/decreased amount of the chips
calculated from the amount of the chips wagered by all the
players and the win or lose result of the game, the game recording
apparatus 11 may allocate indexes or time points to the acquired
images or may reproduce the images specified with a collection
scene or a redemption scene of the chips 9 so that the record
of the game where the difference occurs can be analyzed in the
game recording apparatus 11.
[0045]
In this manner, the control device 14 acquires the total
amount of the chips in the chip tray 17 after the end of the
game and the settlement through the image analyzing apparatus
12, and in this case, the determination after the settlement
is performed at any one of the times 1) to 4) as follows.
1) The time when redemption for the winning chips 9 is
ended.
2) The time when the cards C used in the game are collected
to be discarded into a discard area 41 or a discard slot 42 of
the table;
3) The time when a predetermined button attached to the
win/lose result determining apparatus is pushed; and
4) The time when a marker 43 representing win or lose is
returned to an initial state.
CA 03032770 2019-02-01
[0046]
In addition, the control device 14 has an artificial
intelligence utilizing type structure or a deep learning
structure capable of extracting a strange situation (set by the
casino side) by recognizing the position (position of player,
banker, or pair wagered) and amount (type and number) of the
chips wagered on each play position 7 of the gaming table 4,
comparing the history of win and lose of each player 6 obtained
from win or lose result of each game and the amount of the
acquired chips (winning amount) and the statistical data of a
large number of previous games (big data) . Typically, the
control device 14 has an artificial intelligence utilizing type
structure or a deep learning structure, where, in the case where
an winning amount of a certain amount (one million dollars) or
more occurs and the state that the amount of betting chips at
the lose time is small and the amount of betting chips at the
win time is large at a play position 7 of a certain gaming table
4 continues several games, the state can be extracted as a
strange situation by comparing the state and the statistical
data (big data or the like) of previous games.
[0047]
In addition, the control device 14 (integrated with the
image analyzing apparatus 12) of the fraud detection system has
a structure capable of extracting a strange situation or
specifying individual player 6 at the play position 7 which the
player wins a predetermined amount or more. With respect to
the specifying of the player 6, in the image analyzing apparatus
26
CA 03032770 2019-02-01
12, an image of a face is obtained by extraction of feature points,
and identification number (ID) is provided to specify the player.
In addition, the control device 14 has a caution function of
informing about the existence of the specified player in another
gaming table when the specified player 6 departs and arrives
at the other gaming table. More specifically, a pit manger
managing each gaming table 4 or each table manager (or a dealer)
is informed, so that the strange situation can be further
prevented.
[0048]
In addition, control device 14 is provided with database
storing history of exchange of cash K and the chips 9. By
referring to the database in unit of a predetermined time or
a day, the control device performs comparison determination as
to whether or not the recognized amount of the chips 9 in the
chip tray 17 of the dealer 5 of the gaming table 4 is increased
or decreased according to the paid amount of the chips 9
corresponding to the exchanged cash K or the total amount of
the paid amount of the cash K corresponding to the exchanged
chips 9.
[0049]
In addition, in the above-described example, the history
of win and lose and the amount of the acquired chips (winning
amount) for each play position 7 may be surveiled without
specifying individual player 6. In this case, if each player
6 leaves the seat, the player 6 cannot be tracked. However,
the strange situation where the amount of betting chips at the
27
CA 03032770 2019-02-01
lose time at the specified play position 7 of one game table
4 is small and the state that the amount of betting chips at
the win time is large continues for several games can be detected.
Next, in the case where such a play position 7 is detected, it
is suspected that there is fraud or error at the play position
7. Next, by verifying the video obtained by capturing an image
of the play position 7, the fraud or error can be found.
[0050]
More specifically, the camera 2 is installed to capture
at least an image of the chips 9 placed on the betting area 8
of the gaming table 4. The image analyzing apparatus 12
analyzes the image captured by the camera 2 to detect which of
the positions "player", "banker", and "tie" of the betting area
8 the chips are placed on for each user position 7 and the amount
of the placed chips. In addition, the card distribution device
3 also functions as a win/lose result determining apparatus to
determine the win or lose result of the game. The control device
14 records (surveils) the history of win and lose and the amount
of the acquired chips (acquired amount of chips) for each play
position 7 based on the position (player, banker, or tie) of
the betting area 8 on which the chips 9 are placed and the win
or lose result of the game. In addition, any one of the history
of win and lose and the acquired amount of chips may be recorded.
In the case of a strange situation (set by the casino side) that
the history of win and lose and/or the history of the acquired
amount of chips are strange in comparison with the statistical
data of a large number of previous games (big data) , the control
28
CA 03032770 2019-02-01
device 14 specifies the player position 7 as a play position
where fraud is suspected to occur.
[0051]
In the case where fraud is suspected to occur at a certain
player position 7, the fraud detection system may generate alarm
(light, sound, or vibration) so that at least dealer can
perceive at this time. Therefore, at least at this moment, by
stopping the subsequent game or the like, it is possible to
prevent the fraud from continuously occurring. In addition,
information indicating that fraud is suspected to occur may be
added to the image captured and recorded by the camera 2.
Therefore, by checking video, it is possible to find a cause
of the suspicion of the fraud.
[0052]
The fraud detection system in the casino having the gaming
table according to the embodiment further has a function of
performing inspection at the time of exchange of cash and chips
which is frequently performed in the gaming table 4. In the
casino such as a casino, before a game, the player 6 exchanges
money (cash or the like) and gaming chips at a predetermined
cashier cage. When the player 6 spends all chips, the player
may exchange cash and chips 9 on the gaming table (baccarat table
or the like) to continuously do the game without leaving the
seat from the gaming table 4. However, at the point, there is
a chance of fraud between the dealer 5 and the player. On the
gaming table (baccarat table or the like), the exchange of the
cash and the chip 9 needs to be performed when the game is not
29
CA 03032770 2019-02-01
in progress. In order to determine the win or lose of the game,
the card distribution device 3 can detect card dealing start
and dealing end (time of determining the win or lose) .
Therefore, the card distribution device 3 detects a situation
other than card distributing (dealing) , and the control device
14 detects the exchange of the cash and the chips 9 in the gaming
table 4 in the situation other than the card dealing
(illustrated in FIG. 6) . The card dealing (or the situation
other than the card dealing) can be detected by the card
distribution device 3 or based on the information obtained from
the behavior of the dealer 5.
[0053]
The control device 14 can recognize the number and amount
of cash K by performing the image analysis on the surface of
the cash. In addition, in the gaming table 4, whether or not
the cash K in exchange for the chips 9 is genuine is performed
by irradiating the cash with black light to detect a genuine
mark G of the cash. As illustrated in FIG. 6, the control device
14 has an artificial intelligence utilizing type structure or
a deep learning structure capable of verifying the genuine mark
G through the image analysis, recognizing the total amount of
the genuine cash, recognizing the total amount of the chips even
in the state that a plurality of chips as an exchange object
placed on the gaming table are concealed due to a blind spot
of the camera 2, and comparing the total amount of the cash K
placed on the gaming table 4 by the player and the total amount
of the chips 9 placed by the dealer 5 to determine whether or
CA 03032770 2019-02-01
not the two amounts match with each other.
[0054]
The control device 14 has an artificial intelligence
utilizing type structure or a deep learning structure capable
of performing comparison calculation as to whether or not the
total amount of the chips 9 in the chip tray 17 of the dealer
of the gaming table 4 is increased or decreased according to
the paid amount of the chips corresponding to the exchanged cash
after the exchange of cash and chips and the settlement. The
case where the total amount of the chips 9 in the chip tray 17
of the dealer 5 is always checked by the RFID or the like of
the chips 9 in advance may be considered. In addition, the total
amount of the chips 9 contained in the chip tray 17 can be
detected by capturing an image of the chip tray 17 containing
the chips 9 by using the camera 2 and analyzing the image by
using the image analyzing apparatus 12.
[0055]
In addition, the control device 14 verifies match between
the increase or decrease of the amount of the chips 9 in the
chip tray 17 and the exchanged amount of the chips according
to the result of the image analysis of the gaming table 4 before
and after the exchange of cash and chips. The paid amount of
the cash may be input to the control device 14 by the dealer
5 through key input or the like. The paid amount of the cash
may be specified by the camera 2 capturing an image of the gaming
table 4 where the cash is being paid and by the image analyzing
apparatus 12 analyzing the image.
31
CA 03032770 2019-02-01
[0056]
As described above, the control device 14 determines
whether or not the decreased amount of the chips 9 in the chip
tray 17 due to the exchange of cash and chips matches with the
amount of the cash paid to the dealer 5 by the player 6. In
addition, the control device 14 is an intelligence control
device and has an artificial intelligence utilizing type
structure or a deep learning structure capable of performing
comparison calculation of match or mismatch between the input
amount (typically, obtained by key input or the like) of the
cash by the dealer 5 and the calculated amount of the cash
obtained from the result of the image analysis by the image
analyzing apparatus 12 after the exchange of cash and chips and
the settlement.
[0057]
In addition, the control device 14 has an artificial
intelligence utilizing type structure or a deep learning
structure capable of performing comparison calculation of match
or mismatch between the total input amount of the cash according
to the input by the dealer in the gaming table 4 for which the
dealer is responsible and the total amount of the cash according
to the result of the image analysis by the image analyzing
apparatus 12.
[0058]
The control device 14 performs comparison determination
as to whether or not the recognized amount of the chips 9 in
the chip tray 17 of the dealer 5 of the gaming table 4 is increased
32
CA 03032770 2019-02-01
or decreased according to the paid amount of the chips 9
corresponding to the exchanged cash or the paid amount of the
cash corresponding to the exchanged chips 9 after the exchange
of the cash and the chips 9.
[0059]

[0069]
As described in FIG. 7, in the gaming table 4, the players
(game participants) 6 take seats at the play positions 7 to face
the dealer 5. The player (game participant) 6 performs wagering
(hereinafter, referred to "betting") as to who of the player
and the banker wins or whether the player and the banker ties
as a win or lose result of the baccarat game by placing the chips
9 on the betting area 8 in front of the player ' s eyes. The dealer
counts time in order to end the betting by the players (game
participants) 6 and calls "No More Bet (end of receiving the
betting) " while moving the hand in the transverse direction (the
state illustrated in FIG. 7) . In the baccarat game, during the
36
CA 03032770 2019-02-01
time interval from the time when the "No More Bet (end of
receiving the betting) " is called and card extraction is started
or the dealer 5 performs the game start operation before the
win or lose result of the game is displayed by the card
distribution device 3, the players (game participants) 6 are
cannot operate chips, wager additional chips, or recover the
chips which have been wagered once.
[0070]
After that, the playing cards 1 are extracted one by one
from the card distribution device 3 on the gaming table 4 in
the state that the back side is faced up. First, four cards
are extracted, as illustrated in (1) to (4) of FIG. 7, the first
card goes to the hand of "player", the second card goes to the
hand of "banker", the third card goes to the hand of "player",
and the fourth card goes to the hand of "banker". These cards
are arranged to be distributed to areas 10 (player area 10P and
banker area 10B) on the gaming table 4 in the front side as viewed
from the dealer 5. Next, according to the ranks (numbers) of
the first to fourth cards 1 and the condition in the detailed
rule of the baccarat game, the fifth card 1 and the sixth card
1 are extracted by the dealer 5, and these cards go to the hand
of "player" or "banker". Next, according to the ranks (numbers)
of the first to fourth cards 1 (in some case, the fifth and sixth
cards are combined) and the detailed rule of the baccarat game,
the win or lose of the game is determined. Herein, a game rule
is programmed in the card distribution device 3, and the card
distribution device has a structure where the win or lose of
37
CA 03032770 2019-02-01
the game can be determined by reading information (ranks
(numbers) or suits) of the cards 1 distributed. It is
determined whether or not the win/lose determination result
(win or lose result) determined by the card distribution device
3 matches with the win or lose result determined by the dealer
or the like as described above.
[0071]
Hereinafter, an overview of the fraud detection system
for the game in the embodiment of the invention will be described.
FIG. 7 is a diagram illustrating the overview of the system.
The fraud detection system for the game in the casino is
configured to include a game recording apparatus 11 which
records a progress of the game played in the gaming table 4

image through cameras 2, an image analyzing apparatus 12 which
performs image analysis on the recorded image of the progress
of the game , and a card distribution device 3 which has a function
of determining a win or lose result of each game in the gaming
table 4 and displaying the win or lose result. The card
distribution device 3 is a so-called electronic shoe used by
the skilled in the art and has a structure where a game rule
is programmed in advance, the timing that the cards 1 are
distributed by the dealer 5 at the initial time of each game
is sensed, and the win or lose of the game can be determined
by reading information (rank (number) or suit) of each card 1
distributed. For example, in a baccarat game, banker win,
player win, or tie is basically determined by a rank of two or
38
CA 03032770 2019-02-01
three cards, and a determination result (win or lose result)
is displayed by a display lamp 13.
[0072]
The control device 14 of the fraud detection system has
a chip detecting function of specifying which of the betting
areas 8 of the player side and the banker side on the gaming
table 4 the players 6 (game participants) wager the chips 9 on
by using the result of the analysis of the image analyzing
apparatus 12 in each game. It is assumed that, when the chips
9 are overlapped in a deviated manner or are in a blind spot
from the position of the camera 2, the position and total amount
of the chips 9 (which of the betting areas 8 of the player side
and the banker side the chips 9 are wagered on) cannot be read
normally. The control device 14 is configured to be capable
of recognizing concealing or the like (including concealing of
a portion of one chip and concealing of the entire chip) of the
chip 9 caused by the blind spot, so that the number of chips
or the like can be accurately recognized by using a
self-learning function or the like according to an existing
artificial intelligence utilizing type computer or control
system and deep learning (structure) technique. In addition,
the structure of detecting the position and type of the chip
9 in the betting area 8 is not limited thereto, but for example,
the structure may be configured so that the position and the
type can be detected by reading the ID buried in the chip.
[0073]
As described heretofore, the control device 14 can
39
CA 03032770 2019-02-01
recognize, through the camera 2 and the image analyzing
apparatus 12, the position (position of player, banker, or pair
wagered) on which each player 6 wagers the chips 9 and the type
(different amount values are designated to different colors of
the chips 9) and number of the chips 9, and the control device
can detect who is the player 6 betting on the "player" (in the
case where there are a plurality of the players 6 betting on
the "player", who is the player 6 wagering the highest amount)
and who is the player 6 betting on the "banker" (in the case
where there are a plurality of the players 6 betting on the
"banker", who is the player 6 wagering the highest amount) . In
this fraud detection system, each of the image analyzing
apparatus 12 and the control device 14 has a structure including
a computer configured with an integrated or plural components,
a program, and a memory in a complex manner.
[0074]
The control device 14 has a structure capable of
determining match or mismatch by checking information on rank
and suit obtained from the image (captured by using the camera
2) of each card 1 distributed in the gaming table 4 by the image
analyzing apparatus 12 and information on rank and suit read
by the card distribution device 3. The control device 14
determines by image analysis of a progress of the game through
the image analyzing apparatus 12 according to the win or lose
result of the game determined by the card distribution device
3 for each game whether or not the collection of the lost chips
9 wagered by the players (game participants) 6 and the
CA 03032770 2019-02-01
redemption of the winning chips to the winning player (game
participant) 6 are correctly performed in accordance with the
win or lose result.
[0075]
As remarkable functions of the invention, the control
device 14 has functions described in the following 1) to 5)
according to the rule of the baccarat game and determines
whether or not fraud in discordance with the rule is performed.
Namely, the functions are as follows.
1) Whether or not there is movement of the chips 9 is
surveiled by the information obtained the image analyzing
apparatus 12 using the camera 2 during the time interval from
the signal starting the card extraction obtained from the card
distribution device 3 or from the game start operation of the
dealer 5 pushing a start button 4s before the win or lose result
of the game is displayed by the card distribution device 3 in
each game (illustrated in FIG. 8) .
2) Whether or not the loser 6 takes the chips 9
fraudulently is surveiled by the information obtained the image
analyzing apparatus 12 using the camera 2 during the time
interval when the dealer 5 collects the chips 9 wagered by the
loser among the game participants 6 after the end of each game
(illustrated in FIG. 9) .
3) Whether or not a person (winner or loser) other than
the dealer 5 adds the winning chips 9W or newly places the chips
9 on the winning side which the person did not wager chips on
is surveiled by the information obtained the image analyzing
41
CA 03032770 2019-02-01
apparatus 12 using the camera 2 during the time interval when
the dealer 5 collects the chips 9 wagered by the loser among
the game participants 6 after the end of each game.
4) Whether or not the dealer 5 correctly places the paid
chips 9W on the position of the chips 9 wagered by the winner
among the game participants 6 (illustrated in FIG. 10) is
surveiled by the information obtained the image analyzing
apparatus 12 using the camera 2 after the end of each game.
5) Whether or not the winner 6W among the game participants
6 takes the wagered chips 9 and the paid chips 9W (illustrated
in FIG. 11) is surveiled by the information obtained the image
analyzing apparatus 12 using the camera 2 after the end of each
game (the dealer 5 manipulates the card distribution device 3
to allow the display lamp 13 to display the win or lose result) .
[0076]
The control device 14 performs analysis of the
information obtained by using the camera 2 by the image
analyzing apparatus 12. Namely, although the above-described
surveillance of from 1) to 5) is performed by detecting the
movement of the hands of the dealer 5 and the game participant
6, the movement of the chips, or the movement of the hands and
the movement of the chips by the using the analysis result of
the image analyzing apparatus 12, in a fundamental analysis,

Analysis of Dealer 5 Taking Chips 9 Wagered by Game
Participant 6L (FIGS. 12A to 12C) .
The chips 9 wagered by the game participant 6L losing the
game are collected by the dealer 5. Whether or not the
collection is accurately performed is surveiled by analyzing
the information obtained by using the camera 2 in the image
analyzing apparatus 12. First, a change from the state (FIG.
12A) that the betting chips 9 exist to the state (FIG. 12C) that
the chips do not exist is detected by the image analysis. Next,
an image (FIG. 12B) between the state that the chips 9 exist
and the state that the chips do not exist is analyzed. In the
image (FIG. 12B) between the state that the chips 9 exist and
the state that the chips do not exist, which side the hand 5h
reaches from (from the top side of FIG. 12 or the others) is
analyzed. Fraud is detected in accordance with a rule, that
is, in the case where the hand reaches from the top side (the
hand movement, that is, the hand appears from the top side or
the hand leaves toward the top side) , the hand 5h is determined
as the hand of the dealer 5, and in the case where the hand reaches
from the other directions, the hand movement is determined as
fraud.
[0078]
While the dealer 5 collects the chips 9 wagered by the
game participant 6L losing the game, it is surveiled whether
or not another person takes the lost chips 9 fraudulently (FIGS.
12 and 11) . In the image between the state that the chips 9
exist and the state that the chips do not exist, as illustrated
43
CA 03032770 2019-02-01
in FIG. 12, through analyzing the movement of the loser 6L and
the like among the game participants 6, it is detected by the
image analysis that the hand 6h reaches or moves from the bottom
side of FIG. 12 (actually, from the top side) , and the movement
is determined that the hand 6h or the like other than the hand
of the dealer 5 takes the chips 9, so that it is determined that
fraud occurs.
[0079]
Analysis with Respect to Winning Chip 9, Dealer 5
Correctly Redeeming (Placing) Chips 9W and Winner 6W among Game
Participant 6 Taking Chips
First, with respect to the winning chips illustrated in
FIG. 14A, the chips 9W are redeemed in accordance with the game
rule as illustrated in FIG. 14B. A change from the state
illustrated in FIG. 14A to the state illustrated in FIG. 14B
is detected, and at the same time, whether or not the hand is
the hand 5h of the dealer 5 is detected by the image analysis.
After that, as illustrated in FIG. 14C, now, whether or not the
hand 6h of the winner 6W among the game participants 6 reaches
(moves) the same betting area and, after that, all the chips
9 do not exist (state of FIG. 14D) is verified from the image
analysis result in accordance with the game rule by the control
device 14, so that it is determined whether or not fraud occurs.
[0080]
In addition, the control device 14 is configured to
determine whether or not the amount of chips redeemed to the
winner by the dealer 5 is correct according to the amount wagered
44
CA 03032770 2019-02-01
by the winner 6W among the game participants 6. Hereinafter,
a specific example thereof is described. It is assumed that,
when the chips 9 are overlapped in a deviated manner or are in
a blind spot from the position of the camera 2, the position
and total amount of the chips 9 (which of the betting areas 8
of the player side and the banker side the chips 9 are wagered
on) cannot be read normally. The control device 14 is
configured to be capable of recognizing concealing or the like
(including concealing of a portion of one chip and concealing
of the entire chip) of the chip 9 caused by the blind spot, so
that the number of chips or the like can be accurately recognized
by using a self-learning function or the like according to an
existing artificial intelligence utilizing type computer or
control system and deep learning (structure) technique. In
addition, the structure of detecting the position and type of
the chip 9 in the betting area 8 is not limited thereto, but
for example, the structure may be configured so that the
position and the type can be detected by reading the ID buried
in the chip.
[0081]
As described heretofore, the control device 14 can
recognize, through the camera 2 and the image analyzing
apparatus 12, the position 8 (position of player, banker, or
pair wagered) on which each player 6 wagers the chips 9 and the
type (different amount values are designated to different
colors of the chips 9) and the number of the chips, and the
control device can detect who is the player 6 betting on the
CA 03032770 2019-02-01
"player" (in the case where there are a plurality of the players
6 betting on the "player", who is the player 6 wagering the
highest amount) and who is the player 6 betting on the "banker"
(in the case where there are a plurality of the players 6 betting
on the "banker", who is the player 6 wagering the highest
amount) .
[0082]
In addition, the control device 14 of the fraud detection
system in the game analyze the information obtained by the image
analyzing apparatus 12 using the camera 2 by the above-described
method in accordance with the rule of the baccarat game and
performs surveillance. By performing the surveillance
illustrated in the above-described 1) to 5) , it is determined
whether or not fraud in discordance with the rule is performed.
When fraud is detected, a card distribution sensing device 14C
turns on abnormality display lamps 16 provided to both of the
card distribution device 3 and the gaming table 4 and outputs
15 the fraud detection to a casino management department or the
like in a wireless or wired manner. A monitor or a lamp which
receives the determination result to perform caution or display
may be further provided to another site.
[0083]
As described heretofore, the fraud is detected by the
control device 14, and, at the detecting time or a proper timing,
a display signal is output to the display lamp 13 of the card
distribution device 3 or the abnormality display lamp 16.
However, besides the performing of caution, after the time when
46
CA 03032770 2019-02-01
the fraud or error is detected, a card distribution preventing
function of the card distribution device 3 may be performed to
prevent the distribution of the cards 1.
[0084]
Hereinafter, an embodiment of the card distribution
device 3 used in a table game system according to the invention
will be described with reference to FIGS. 15 to 19. The card
distribution device 3 is configured to include a card containing
portion 102 which contains a plurality of shuffle playing cards
is, a card guiding portion 105 which guides the shuffle playing
card 1 when the dealer 5 or the like manually extracts the shuffle
playing card 1 one by one from the card containing portion 102
toward the gaming table 4, an opening portion 106 for taking
the card 1 guided from the card guiding portion 105, a card
detecting unit (card detecting sensors 22 and 23) which detects
that the shuffle playing card 1 is extracted when the shuffle
playing card 1 is extracted, a card reading unit 108 which reads
information representing at least the number (rank) of the
shuffle playing card 1, a control unit 109 which determines the
win or lose of the card game based on the numbers (ranks) of
the shuffle playing cards 1 sequentially read by the card
reading unit 108, a result display lamp 13 which displays the
win or lose result determined by the control unit 109, a
distribution restricting device 30 which is provided to the
opening portion 106 and restricts entering and exiting of the
card 1 from the card containing portion 102, and a management
control unit 114 having functions equivalent to the control
47
CA 03032770 2019-02-01
device 14, and these components are integrated. The card
distribution device has a function where, in the case where
error or fraud of the dealer in the game is detected by the
control device 14, the further extraction of the card from the
card distribution device 3 is stopped after the time of the
detection or at a predetermined timing.
[0085]
Next, the distribution restricting device 30 which
restricts the entering and exiting of the cards 1 from the card
containing portion 102 will be described with reference to FIGS.
16 and 17. The distribution restricting device 30 is provided
to a card guide 107 of the card guiding portion 105 which guides
the card 1 extracted one by one from the opening portion 106
in the front side of the card containing portion 102 onto the
gaming table 4. The distribution restricting device 30 has a
structure where, when the card 1 passes through a slot 33 between
the card guiding portion 105 and the guide cover of the card
guide 107, a lock member 34 presses the card 1 to prevent the
entering and exiting of the card 1 in the slot 33. The lock
member 34 is moved by a driving unit 35 such as an electronic
solenoid or a piezoelectric device as illustrated by an arrow
m so as to take two states of a position (limiting position)
of pressing the card 1 and a pass enabling position of enabling
the card 1 to pass. The driving unit 35 is controlled by a
control unit 109 which is directly or indirectly connected to
the control device 14 in a wired or wireless manner to move the
lock member 34 to the two states of the position of pressing
48
CA 03032770 2019-02-01
the card 1 and the pass enabling position of enabling the card
1 to pass. The rule of the baccarat game is programed and stored
in advance in the control unit 109.
[0086]
Next, a modified example of the distribution restricting
device 30 will be described with reference to FIG. 18B. In the
modified example, the distribution restricting device 40 has
a structure where, when the card 1 passes through the slot 33
between the card guiding portion 105 and the card guide 107
(guide cover) , the lock member 36 projects into the slot 33 to
prevent the movement of the card 1. The lock member 36 is moved
by a driving unit 37 such as an electronic solenoid or a
piezoelectric device as illustrated by an arrow m so as to take
two states of a position (limiting position) of preventing the
movement of the card 1 and a pass enabling position of enabling
the card 1 to pass. The driving unit 37 is controlled by the
control unit 109 which is connected to the control device 14
to move the lock member 36 to the two states of the position
of preventing the movement of the card 1 and the pass enabling
position of enabling the card 1 to pass.
[0087]
Next, details of the code reading unit 108 which reads
a code 52 representing a digit (number, rank) of the card 1 from
the card 1 when the card 1 is manually extracted from the card
containing portion 102 will be described. FIG. 17 is a plan
diagram illustrating main components of the card distribution
device 3. In the figure, the code reading unit 108 is provided
49
CA 03032770 2019-02-01
to the card guiding portion 105 which guides the card 1 manually
extracted one by one from the opening portion 106 in the front
side of the card containing portion 102 onto the gaming table
4. The card guiding portion 105 is formed to have a slanted
surface, and the card guides 107 functioning as a sensor cover
are provided to two edges of the card guiding portion. In
addition, each of the two card guides 107 is formed detachable
by using a screw or the like (not shown). If the card guides
107 are detached, sensor groups 115 of the code reading unit
108 are exposed. The sensor group 115 is configured with four
sensors including two UV-ray sensitive sensors (UV sensors) 20
and 21 and object detection sensors 22 and 23.
[0088]
The object detection sensors 22 and 23 are optical-fiber
type sensors of detecting the existence of the card 1 and can
detect the movement of the card 1. One object detection sensor
22 is located at the upstream side of the card guiding portion
105 in the card 1 flowing direction, and the other object
detection sensor 23 is located at the downstream side. As
illustrated in the figure, the two object detection sensors 22
and 23 are provided at the respective upstream and downstream
sides to interpose the UV sensors 20 and 21. The UV sensors
20 and 21 have LEDs (UV LEDs) emitting a UV ray and sensors.
A mark M of the code 52 is printed on the card 1 by using UV
ray emitting ink which exhibits color if the ink is hit by the
UV ray. By irradiating the card 1 with the UV ray (black light) ,
reflected light of the mark M of the code 52 of the card 1 is
CA 03032770 2019-02-01
sensed by the sensor. The UV sensors 20 and 21 are connected
to the code reading unit 108 and the control unit 109 through
cables. In the code reading unit 108, a combination of the marks
M is determined and the number (rank) corresponding to each code
52 is determined from the output signal of the sensors, that
is, the UV sensors 20 and 21.
[0089]
In the code reading unit 108, starting and ending of the
UV sensors 20 and 21 are controlled by the control unit 109 based
on the detection signals of the object detection sensors 22 and
23. In addition, the control unit 109 determines based on the
detection signals of the object detection sensors 22 and 23
whether or not the card 1 passes through the card guiding portion
105 normally. As illustrated in FIG. 19, two rows and four
columns of the rectangular marks M representing the rank
(number) and suit (heart, spade, or the like) of the card are
arranged in the edge of the card 1. If the UV sensors 20 and
21 sense the mark M, the sensors output "on" signals. The code
reading unit 108 determines a relative relationship between the
two signals input from the two UV sensors 20 and 21. Therefore,
the code reading unit 108 specifies the code according to a
relative difference between the two marks M sensed by the two
UV sensors 20 and 21 to specify the number (rank) and type (suit)
of the corresponding card 1.
[0090]
The relationship between the code 52 and the outputs of
the "on" signals of the two UV sensors 20 and 21 is illustrated
51
CA 03032770 2019-02-01
in FIG. 19. Based on the result of comparison of the relative
change of the outputs of the "on" signals of the UV sensors 20
and 21, a predetermined combination of the marks M can be
specified. As a result, four combinations of the marks M of
the up and down two columns are obtained, and if the four
combinations are printed in four columns, 4 to the 4th power,
that is, 256 types of codes can be configured. By assigning
52 types of cards of the playing cards to 256 types of the codes,
details of the assignment is stored as a comparison table in
a memory or as a program, and the code reading unit 108 is
configured so that, by specifying each code 52, the number
(rank) and type (suit) of the card 1 is specified from a
pre-defined comparison table (not shown) . In addition, since
the 256 types of the codes are stored in the comparison table
in a manner that the codes are freely combined to be in
association with the 52 types of the cards, the combinations
may be complicated, and thus, the combinations of the 256 types
of the codes and the 52 types of the card can be changed according
to time and location. It is preferable that the code is printed
by using a paint which is visualized by being irradiated with
UV light and the code is printed at a position where the codes
do not overlap a type indicator or index 103 of the card.
[0091]
In addition, in the above-described embodiment, although
the image analyzing apparatus 12 or the control device 14 is
a device having an artificial intelligence utilizing type
structure or a deep learning structure, specifically, the image
52
CA 03032770 2019-02-01
analyzing apparatus 12 or the control device 14 may perform
image analysis or the above-described various controls by using
scale-invariant feature transform (SIFT) algorithm,
convolution neutral network (CNN) , deep learning, machine
learning, or the like. Such a technique is a technique of
performing image recognition on a captured image to recognize
an object included in the image. Particularly, in recent years,
object recognition at high accuracy is performed by using a deep
learning technique utilizing a multilayered neutral network.
In the deep learning technique, generally, layers covering
multiple stages are overlapped in intermediate layers between
an input layer and an output layer of the neutral network, so
that the object is recognized at high accuracy. In the deep
learning technique, particularly, a convolution neutral
network has drawn attention because the convolution neutral
network has higher performance than the object recognition
based on image feature amounts in the related art.
[0092]
In the convolution neutral network, recognition object
images attached with label are learned, and main objects
included in the recognition object image are recognized. In
the case where a plurality of the main objects exist in the
learned image, an area rectangle is specified, and the image
corresponding to the specified area is attached with a label
and the learning is performed. In addition, in the convolution
neutral network, the main objects in the image and the positions
of the objects can also be determined.
53
CA 03032770 2019-02-01
[0093]
As the convolution neutral network is described more in
detail, in the object recognition process, edge extraction
process and the like is performed on the recognition object
image, candidate areas are extracted based on localized
features, the candidate areas are input to the convolution
neutral network to extract feature vectors, classification is
performed, and the candidate area having the highest degree of
certainty among the classified candidate areas is acquired as
a result of the recognition. The degree of certainty is a
quantity representing how higher a degree of similarity between
a certain image area and a subject of the image learned together
with the label is than the degree of similarity of another class.
[0094]
In addition, devices having an artificial intelligence
utilizing type structure or a deep learning structure are
disclosed in US 9,361,577, US 2016-171336 A, US 2015-036920 A,
JP 2016-110232 A, and these disclosures are incorporated into
this specification by reference.
[0095]
Heretofore, although various embodiments of the
invention are described, the above-described embodiments can
be modified within the scope of the invention by the skilled
in the art, and if needed in a game to which the embodiment is
applied, the apparatus according to the embodiment may be
appropriately modified.

4 (an area where the player places the chips 9 in order for
betting), the card distribution device 3, and the chip tray 17.
The camera 2 is capable of obtaining an image by capturing the
bet chips.
[0140]
Furthermore, in the example of FIG. 20, one camera 2 is
disposed on each of the gaming tables 4, but a plurality of
cameras 2 of which at least one of the dispose positions, the
capturing directions, or the angular fields are different from
CA 03032770 2019-02-01
each other, may be disposed on each of the gaming tables 4 to
capture different ranges. For example, the camera 2 capturing
the betting area and the camera 2 capturing the chip tray 17
may be separately disposed, or the same betting area may be
captured by a plurality of cameras of which the disposition
heights are different from each other, and the capturing
directions are different from each other.
[0141]
A control device 14 is further disposed on each of the
gaming tables 4. The control device 14 is connected to the
camera 2 of the gaming table 4 (in a case where the number of
cameras 2 is plural, a plurality of cameras 2), the card
distribution device 3, and the RF antenna 173. The control
device 14 has a plurality of functions as an information

[0142]
First, the control device 14 has a function as an RF reader,
which specifies the type of all of the chips 9 contained in the
chip tray 17, on the basis of the electrical wave received by
the antenna 173, calculates the total amount of the chips 9
contained in the chip tray 17, and records the total amount.
In addition, the control device 14 has a function of receiving
the win or lose result of each of the games from the card
distribution device 3, and of recording the result. Further,
the control device 14 has a function as an image recognition
device, which acquires a captured image from the camera 2,
performs image recognition using a machine learning model, with
71
CA 03032770 2019-02-01
respect to the captured image, and recognizes betting contents,
that is, how much the player bets on the betting target, which
player bets, which betting target the player bets on, as with
the first embodiment and the second embodiment. The machine
learning model may be a neural network of a deep learning
structure. Specifically, the control device 14 specifies the
player and the betting target on the basis of the positions of
the chips 9 in the captured image, and specifies the betting
amount on the basis of the type and the number of chips 9 in
the captured image.
[0143]
Thus, the control device 14 recognizes the total amount
of the chips 9 contained in the chip tray 17 (hereinafter, also
referred to as a "dealer amount") by using the antenna 173,
recognizes the win or lose result of the game (hereinafter, also
referred to as a "game result") by using the card distribution
device 3, and recognizes the betting contents by using the image
from the camera 2, for each game, on each of the gaming tables
4. It is possible to calculate the sales and the profit of the
casino manager in each of the games, on the basis of such
information (the chip tray total amount, the game result, and
the betting contents).
[0144]
The game management system 100 includes a management
device 50 connected to the control device 14 of the plurality
of gaming tables 4. The management device 50 is configured of
a general-purpose computer. The management device 50 includes
72
CA 03032770 2019-02-01
an arithmetic device 51 and a recording apparatus 52. The
general-purpose processor executes a computer program of this
embodiment, and thus, the arithmetic device 51, for example,
is realized. The arithmetic device 51 includes a calculation
unit 511, a table creation unit 512, and an alarming unit 513.
[0145]
The calculation unit 511 acquires the information of the
dealer amount, the game result, and the betting contents for
each game, from the plurality of control devices 14, and
calculates the sales, the profit (the gross), and the profit
rate (a gross rate) for each gaming table 4. The table creation
unit 512 creates a table and a graph in which the sales and the
profits calculated by the calculation unit 511 are arranged in
time series for each table.
[0146]
Furthermore, the calculation unit 511 may calculate the
sales, the profit, and the profit rate for each position of the
player on each of the gaming tables 4, and the table creation
unit 512 may create the table and the graph in which the sales,
the profits, and the profit rates are arranged in time series
for each position of the player on each of the gaming tables
4. In addition, in a case where the game management system 100
includes a section recognizing the player, the sales according
to the betting of the player and the profit obtained from the
player may be calculated, and the table and the graph may be
created, for each player.
[0147]
73
CA 03032770 2019-02-01
The recording apparatus 52 records the sales, the profit,
and the profit rate calculated by the calculation unit 511, in
the form of the table and the graph created by the table creation
unit 512.
[0148]
Specifically, the calculation unit 511 calculates the
total amount (the sales) of the betting amount for each of the
plurality of gaming tables 4 and each game, obtains the degree
of collection or the redemption with respect to which betting
target, on the basis of the betting target, the betting amount,
and the game result, and calculates the profit of the casino
manager. In addition, the calculation unit 511 obtains a
difference in the dealer amount before and after the table game,
for each of the plurality of gaming tables 4 and each game, and
thus, calculates the profit of the casino manager. The profit
of the former is a so-called theoretical value, and the profit
of the latter is a so-called result value, and it is necessary
that the theoretical value and the result value are coincident
with each other. The calculation unit 511 determines whether
or not the theoretical value and the result value are coincident
with each other, and in a case where the theoretical value and
the result value are coincident with each other, the profit is
adopted, and in a case where the theoretical value and the result
value are not coincident with each other, a warning to that
effect may be generated.
[0149]
The calculation unit 511 further calculates the total
74
CA 03032770 2019-02-01
amount (the sales) of the betting amount for each of the
plurality of tables 4 and each game. In addition, the
calculation unit 511 calculates the profit rate (the gross rate)
(= Profit/Sales) on the basis of the sales and the profit (the
gross) of a predetermined period or a predetermined number of
games.
[0150]
The table creation unit 512 adds up the sales, the profit,
and the profit rate calculated by the calculation unit 511, and
creates various tables and graphs. FIG. 21 is an example of
a table indicating the sales (the total amount of the betting
amount) for each gaming table 4, created by the table creation
unit 512. As illustrated in FIG. 21, the table creation unit
512 creates a table indicating the number of bet chips 9 of each
type for each gaming table 4. The number of respective chips
9, for example, may be an added-up number for each predetermined
time such as a time period from 0 hours to 0 hours on the next
day. In a case where the casino facilities are not in 24-hour
operations, the number of respective chips 9 may be an added-up
number for each business hour for one day. Further, the number
of respective chips 9 may be an added-up result within a
predetermined time in the past, on the basis of a creation time.
The table further includes the total amount of chips (the sales)
in each of the gaming tables 4. According to the table, it is
possible to compare the sales in the same time zone for each
gaming table, and to know the total sales of the all of the casino
facilities in the time zone.
CA 03032770 2019-02-01
[0151]
FIG. 22 is an example of a table indicating the sales for
each game in each of the gaming tables 4, created by the table
creation unit 512. FIG. 22 is a table illustrating the sales
with respect to Table 1. As illustrated in FIG. 22, the table
creation unit 512 creates a table indicating the number of
various bet chips 9 for each game. The table creation unit 512
may create one table by separating the table for certain period
of time (for example, 24 hours or one business day) , or may create
a table for each predetermined number of games (for example,
80 games) . In addition, the table creation unit 512 may create
a table within a predetermined time in the past or for a
predetermined number of games, at a table creation time point.
[0152]
FIG. 23 is an example of a table indicating the total
amount of the betting amount (the sales) , the profit (the gross) ,
and the profit rate for each gaming table 4, created by the table
creation unit 512. As illustrated in FIG. 23, the table
creation unit 512 creates a table indicating the total amount
of the betting amount (the sales) (the total betting amount) ,
the profit (the gross) (the gross profit) , the profit rate (the
gross rate) (= Profit/Sales) (a profit ratio) for each gaming
table 4. The table creation unit 512 may create one table by
separating the table for a certain period of time (for example,
24 hours, one week, one month, or the like) , or may create a
table for each predetermined number of games (for example, 100
games, 1000 games, or the like) . In addition, the table
76
CA 03032770 2019-02-01
creation unit 512 may create a table within a predetermined time
in the past or for a predetermined number of games, at a table
creation time point.
[0153]
FIG. 24 is an example of a polygonal line graph
illustrating a transition of the profit in each of the gaming
tables 4, created by the table creation unit 512, and FIG. 25
is an example of a graph illustrating a transition of the profit
of all of the casino facilities. In case where the casino
facilities are operated from 8 a.m. to 6 a.m. on the next day,
the transition of the profit for one business day is illustrated
in the examples of FIG. 24 and FIG. 25. According to the graph
as illustrated in FIG. 24 or FIG. 25, the transition of the prof it
is easily understood, and thus, it is possible to perform
business analysis of the casino facilities. In addition, the
transition of the profit for each table is indicated as
illustrated in FIG. 24, and thus, a table having a peculiar
transition of the profit is easily found.
[0154]
FIG. 26 is an example of a bar graph illustrating a profit
rate for each gaming table 4, created by the table creation unit
512. According to the bar graph, the quantity of the profit
obtained in each of the gaming tables 4 becomes obvious.
[0155]
Furthermore, in the examples described above, the
calculation unit 511 and the table creation unit 512 calculate
the sales, the profit, and the profit rate for each gaming table
77
CA 03032770 2019-02-01
4, and create the table or the graph, but instead thereof or
in addition thereto, may calculate the sales, the profit, and
the profit rate for each pit in which the plurality of gaming
tables 4 are collected, and may create a table or a graph.
[0156]
The calculation unit 511 may calculate the sales, the
profit, and the profit rate whenever the information of the
dealer amount, the game result, and the betting contents is
acquired for each game, or may calculate the sales, the profit,
and the profit rate at a timing when the table creation unit
512 creates a table.
[0157]
The table creation unit 512 may create a table for each
period targeted by the table or the graph. For example, in a
case where the table creation unit 512 creates a graph
illustrating a transition of the sales for one day (for 24 hours)
on each of the gaming tables 4, the table may be automatically
created every 24 hours (as soon as the data is collected) .
Alternatively, the table creation unit 512 may create the table
or the graph at a manually indicated timing, regardless of the
period targeted by the table or the graph. Alternatively, the
table creation unit 512 may automatically create the table or
the graph at an interval shorter than the period targeted by
the table or the graph. For example, adding-up for 24 hours
in the past may be performed every 6 hours, and thus, the table
or the graph may be created.
[0158]
78
CA 03032770 2019-02-01
The alarming unit 513 determines that a peculiar
situation occurs on the basis of the sales, the profit, and the
profit rate calculated by the calculation unit 511, and the
adding-up of the table creation unit 512, and generates an alarm.
For example, the alarming unit 513 may compare the profit rate
calculated by the calculation unit 511 or the profit rate for
a predetermined period or for a predetermined number of games,
added up by the table creation unit 512, with a predetermined
first threshold value, and may generate an alarm when the prof it
rate is less than or equal to the first threshold value, or may
compare the profit rate calculated by the calculation unit 511
or the profit rate for a predetermined period or for a
predetermined number of games, added up by the table creation
unit 512, with a predetermined second threshold value, and may
generate an alarm when the profit rate is greater than or equal
to the second threshold value. In addition, the alarming unit
513 may compare the profit and the sales with a predetermined
threshold value, and thus, may generate an alarm.
[0159]
The alarming unit 513 may perform more complicated
analysis with respect to the sales or the profit, and may find
a peculiar situation. For example, the alarming unit 513 may
generate an alarm on the basis of the transition of the profit
rate in the table or graph created by the table creation unit
512. In this case, the peculiar situation may be determined
by using the machine learning model. The machine learning model
may be a model of outputting a probability of being peculiar
79
CA 03032770 2019-02-01
by using the transition of the profit rate obtained by the
adding-up of the table creation unit 512 as input, and in a case
where the probability is less than or equal to a predetermined
threshold value, the alarming unit 513 may determine that it
is the peculiar situation, and may generate an alarm.
[0160]
The alarm may be realized by a section of attaching a mark
to an element which is determined as being peculiar in the table
or the graph created by the table creation unit 512, and in
addition, in a case where such a peculiar situation occurs, the
alarm may be realized by generating and outputting an image,
a sound, a driving signal of an alarm device (a lamp, a buzzer,
or the like) , and the like. In the example of FIG. 23, the alarm
is realized by hatching Table 3 in which the profit rate is less
than 0%.
[0161]
As described above, according to the third embodiment,
in the game table 4, the bet contents are determined by the camera
2 and the control device 14 as the image recognition device,
the game result is determined by the card distribution device
3, and the dealer amount is determined by the antenna and the
RF reader and the information is intensively managed by the
management devices 50 and 60, and as a result, it is possible
to automatically determine the sales, the profit, the profit
rate, etc. of a casino operator.
[0162]
In the embodiment described above, the win or lose
CA 03032770 2019-02-01
determination device is realized by the card distribution
device 3, that is, the card distribution device 3 has a
configuration of performing win or lose determination, but the
win or lose determination may be performed by the control device
14. In this case, from the card distribution device 3, the
information read out from the distributed card (card reading
information) is transmitted to the control device 14, and the
control device 14 determines the win or lose result of the game
according to the game rule, on the basis of the card reading
information from the card distribution device 3, as the win or
lose determination device.
[0163]
In addition, in the embodiment described above, the
calculation unit 511 calculates the sales, the profit, and the
profit rate, and the table creation unit 512 creates the table
or the graph by adding up the calculated sales, profit, and
profit rate, but instead thereof, apart or all of the adding-up
may be performed by the calculation unit 511, and the table
creation unit 512 may create the table or the graph by using
the added-up result of the calculation unit 511.
