[0003] The present invention relates to a game monitoring system for monitoring a game. Background Art

[0004] In the past, in the games played in casinos, the games played by players were monitored to detect cheating, conduct customer ratings, etc. The games, the bets played by players, the calculation of the bets, etc. are all performed electronically, so that the results of the games, the bets played by players, the wins and losses of players, and the amounts thereof can be grasped as electronic information. As an example of a document related to the prior art, International Publication No. 2022 / 085706 is cited. Summary of the invention

[0005] In real table games using physical game tables, game cards, and game coins, there is also a desire to monitor the game and to know the amount placed by the player, the amount won, the amount lost, etc. For this reason, in the conventional game monitoring system, RFID is embedded in the game coins, and the RFID is read in the placement area or the game coin tray of the game table to monitor the movement of the game coins on the game table, or the player is asked to show a membership card to identify the player.

[0006] An object of the present invention is to provide a game monitoring system for monitoring a game in a real table game.

[0007] The game monitoring system of the first mode has the following structure, which includes: a game coin ID determination mechanism, which determines the game coin ID of the game coin when the game coin with the game coin ID is located in a specified area on the game table; a shooting mechanism, which shoots the players playing the game on the game table and the game coins on the game table and generates an image; a player detection mechanism, which detects the player from the image; a game coin detection mechanism, which detects the game coin from the image; a first associating mechanism, which associates the first game coin detected by the game coin detection mechanism with the player detected by the player detection mechanism as the player who places the first game coin; a second associating mechanism, which associates the game coin ID of the first game coin determined by the game coin ID determination mechanism with the player associated with the first game coin through the first associating mechanism; and a recording mechanism, which records the combination of the game coin ID of the first game coin and the image of the player associated with the game coin ID of the first game coin through the second associating mechanism.

[0008] According to this configuration, for a coin located in a predetermined area on a gaming table, the coin ID is associated with the player who placed the coin and recorded, and therefore, the game can be monitored during a real table game.

[0009] The game monitoring system of the second mode has the following structure based on the game monitoring system of the first mode, and the structure also includes: a storage mechanism, which stores the game coin ID of the game coin in association with its owner; and a comparison mechanism, which compares the owner associated with the game coin ID of the first game coin in the storage mechanism and the player associated with the game coin ID of the first game coin through the second association mechanism, and outputs a signal indicating inconsistency when the owner associated with the game coin ID of the first game coin in the storage mechanism and the player associated with the game coin ID of the first game coin through the second association mechanism are inconsistent.

[0010] According to this configuration, when the person stored as the owner of a coin placed in a predetermined area of ​​the gaming table and the person identified as the player who placed the coin based on the image are not the same, this fact can be notified.

[0011] The game monitoring system of the third mode has the following structure based on the game monitoring system of the second mode: the player is attached with a player ID, and the game monitoring system also has a player ID determination mechanism, which determines the player ID of the player detected by the player detection mechanism, and the storage mechanism stores the game coin ID of the game coin in association with the player ID of the player who is the owner of the game coin, and the comparison mechanism compares the player ID of the owner associated with the game coin ID of the first game coin in the storage mechanism and the player ID determined by the player ID determination mechanism for the player associated with the game coin ID of the first game coin through the second association mechanism, and when the player ID of the owner associated with the game coin ID of the first game coin in the storage mechanism and the player ID of the player associated with the game coin ID of the first game coin through the second association mechanism are inconsistent, a signal indicating inconsistency is output.

[0012] According to this configuration, when the ID of the person stored as the owner of a coin placed in a predetermined area of ​​the gaming table does not match the ID of the person identified as the player who placed the coin based on the image, this fact can be notified.

[0013] The game monitoring system of the fourth mode has the following structure based on the game monitoring system of the second mode: the storage mechanism stores the game coin ID of the game coin in association with the facial information of the owner of the game coin, and the comparison mechanism compares the facial information associated with the game coin ID of the first game coin in the storage mechanism and the facial information extracted from the image for the player associated with the first game coin through the second association mechanism, and when the facial information associated with the game coin ID of the first game coin in the storage mechanism and the facial information extracted from the image for the player associated with the first game coin through the second association mechanism are inconsistent, a signal indicating inconsistency is output.

[0014] According to this structure, for a game coin placed in a specified area of ​​the game table, if the facial information of the person stored as the owner of the game coin and the facial information of the person determined as the player who placed the game coin based on the image are inconsistent, this situation can be reported.

[0015] The game monitoring system of the fifth mode has the following structure based on the game monitoring system of the second mode, and the structure also includes a control mechanism, which is configured to rewrite the owner associated with the game coin ID of the first game coin in the storage mechanism to the player associated with the game coin ID of the first game coin through the second association mechanism when the comparison mechanism determines that the owner associated with the game coin ID of the first game coin in the storage mechanism and the player associated with the game coin ID of the first game coin through the second association mechanism are inconsistent.

[0016] According to this configuration, the owner stored in association with the coin ID of the coin can be rewritten to the correct owner.

[0017] The sixth mode of the game monitoring system is based on the second mode of the game monitoring system and has the following structure, which also includes: an updating mechanism that rewrites the owner associated with the game coin ID of the payment game coin paid by the dealer in the storage mechanism to the player associated with the payment game coin through the second association mechanism.

[0018] According to this configuration, the owner stored in association with the coin ID of the coin paid out by the dealer can be rewritten to the player who receives the payment of the coin.

[0019] The game monitoring system of the seventh mode has the following structure based on the game monitoring system of the second mode, which also has an updating mechanism, which rewrites the owner associated with the game coin ID of the payment game coin paid by the dealer in the storage mechanism to the player associated with the first game coin moved out of the specified area together with the payment game coin through the second association mechanism.

[0020] According to this configuration, the owner stored in association with the coin ID of the coin paid out by the dealer can be rewritten to the player who placed the coin and to whom the coin is to be paid out.

[0021] The eighth mode of the game monitoring system is based on the game monitoring system of any one of the first to seventh modes and has the following structure: the game coin has an RFID tag storing the game coin ID, and the game coin ID determination mechanism determines the game coin ID of the game coin by reading the game coin ID from the RFID tag.

[0022] According to this structure, the token ID can be identified by RFID.

[0023] The game monitoring system of the ninth mode has the following structure based on the game monitoring system of any one of the first to eighth modes: the game coin has a game coin ID mark on the side, and the game coin ID determination mechanism determines the game coin ID of the game coin by detecting the game coin from an image displaying the game coin and interpreting the game coin ID on the side of the detected game coin.

[0024] According to this structure, the token ID can be identified by the marking on the side.

[0025] The game monitoring system of the tenth mode has the following structure based on the game monitoring system of the first mode: the player detection mechanism detects the player's hand, and the first association mechanism associates the two based on the positional relationship between the player's hand detected by the player detection mechanism and the game coin detected by the game coin detection mechanism.

[0026] According to this configuration, the coin ID of the coin can be associated with the player based on the positional relationship between the hand and the coin.

[0027] The game monitoring system of the eleventh mode has the following structure based on the game monitoring system of the first mode: the game coin ID determination mechanism detects the game coin from the second image generated by the shooting mechanism and determines the game coin ID of the detected game coin, the game coin detection mechanism detects the game coin from a first image different from the second image generated by the shooting mechanism, and the second associating mechanism determines the game coin located at the same position as the first game coin based on the relationship between the position of the game coin detected by the game coin ID determination mechanism in the second image and the position of the game coin detected by the game coin detection mechanism in the first image.

[0028] According to this configuration, it is possible to identify the medals located at the same position in the two images as the same medal.

[0029] The game monitoring system of the twelfth mode has the following structure based on the game monitoring system of the eleventh mode, wherein the shooting mechanism comprises: a first camera for generating the first image, and a second camera different from the first camera for generating the second image, and the second associating mechanism determines the game coins located at the same position as the first game coins by converting the positions of the game coins detected by the game coin ID determination mechanism in the second image and the positions of the game coins detected by the game coin detection mechanism in the first image into a common coordinate space.

[0030] According to this configuration, by mapping the token in one of the two images with the other image, tokens located at the same position can be identified as the same token.

[0031] The game monitoring system of the thirteenth embodiment has the following structure based on the game monitoring system of the first embodiment: the game coin ID determination mechanism determines the position of the game coin whose game coin ID has been determined on the game table, the game coin detection mechanism determines the position of the game coin detected from the image on the game table, and the second associating mechanism determines the game coin located at the same position as the first game coin based on the position determined by the game coin ID determination mechanism and the position determined by the game coin detection mechanism.

[0032] According to this configuration, based on the positions of the coins on the gaming table in the two images, coins located at the same position can be identified as the same coin.

[0033] The game monitoring system of the fourteenth embodiment has the following structure based on the game monitoring system of the first embodiment: the game coin ID determination mechanism determines the moment when the game coin whose game coin ID has been determined is placed on the game table, the game coin detection mechanism determines the moment when the game coin detected from the image is placed on the game table, and the second associating mechanism determines the game coin placed on the game table at the same moment as the first game coin based on the moment determined by the game coin ID determination mechanism and the moment determined by the game coin detection mechanism.

[0034] According to this configuration, it is possible to determine, based on the time when the coin is placed on the game table, that the coin identified by the coin ID identification unit and the coin identified by the coin detection unit are the same coin. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Hereinafter, the modes for implementing the invention are described, but the embodiments described below are merely examples, and the present invention is not limited to the embodiments described below. In addition, the elements of the plurality of embodiments can be arbitrarily combined.

[0041] Figure 1 2 is a diagram showing a game table to which a game monitoring system according to an embodiment of the present invention is applied. Figure 1 As shown, the game monitoring system 100 of this embodiment can be applied to a game table 110 in a casino or the like.

[0042] The game table 110 has a substantially oval tabletop 111. The dealer is located on one side of the tabletop 111, and a player position is provided on the opposite side thereof, where multiple players can be located. Each player position is provided with a placement area 112 for each player position. In this embodiment, the game table 110 is a game table for a certain card game. The placement area 112 includes placement object areas for player, banker, tie, player pair, and banker pair as placement objects.

[0043] The game table 110 is provided with a first camera 11 and a second camera 12. The viewing angle and direction of the first camera 11 are set so as to be able to photograph the placement area 112, the game coins (placed game coins) placed in the placement area 112, and the players playing games on the game table 110. The viewing angle and direction of the second camera 12 are set so as to be able to photograph the placement area 112 and the game coins (placed game coins) placed in the placement area 112, and to display the game coins larger than the first camera 11. The first camera 11 and the second camera 12 are mounted on rods 113 and 114 provided on the game table 110. It should be noted that in order to share the shooting range, multiple first cameras 11 and multiple second cameras 12 can be provided.

[0044] Figure 2 is a side view of a gaming coin according to an embodiment of the present invention. Figure 3 2 is a top view of a game coin according to an embodiment of the present invention. Figure 2 As shown, a center line 51 is provided in the center of the thickness direction in the side of the game coin 50. The color of the center line 51 indicates the type (value) of the game coin 50. Thus, by observing the side of the game coin 50, the value of the game coin 50 can be known by the color of the center line 51.

[0045] The center line 51 is marked with a game coin ID for determining the game coin 50 as code information. In the game coin 50 of this embodiment, the code information representing the game coin ID is represented by the presence or absence of multiple dots arranged in two rows above and below. That is, binary information is represented by the presence or absence of dots in each column above and below, and 5 bytes of information are represented by a dot matrix of 20 columns. It should be noted that multiple dots representing the game coin ID can be printed on the side of the game coin 50 using ink that cannot be visually confirmed under natural light but can be visualized by irradiating infrared or ultraviolet rays.

[0046] like Figure 3 As shown, the surface and back of the game coin 50 are marked with numbers representing its value. Of course, the color of the center line of this number and the side is corresponding.

[0047] Figure 4 1 is a block diagram showing the structure of a game monitoring system according to an embodiment of the present invention. The game monitoring system 100 includes an information processing device 20 and a database 40 in addition to the first camera 11 and the second camera 12 described above. The first camera 11 and the second camera 12 are respectively connected to the information processing device 20 so as to be communicable. In addition, the information processing device 20 is connected to the database 40 so as to be communicable.

[0048] The information processing device 20 may be provided at each game table 110, or the first camera 11 and the second camera 12 respectively provided at a plurality of game tables 110 may be connected to one information processing device 20. In addition, the database 40 may be respectively provided at a plurality of game tables 110, or one database 40 may be provided for a plurality of game tables 110. In addition, the database 40 may be provided on the cloud.

[0049] The first camera 11 and the second camera 12 respectively shoot and generate images when the player places the game coin 50 in the placement area 112 of the game table 110 or even when the game coin 50 is placed in the placement area 112 and the game starts (that is, from then on, the game coin 50 is not allowed to be moved).

[0050] The information processing device 20 is a computer composed of a memory used as a temporary storage area, a processor that performs calculations corresponding to input signals according to the information processing program of this embodiment, and a storage device that stores various data. The database 40 includes a storage device and a processing device, and the processing device performs processing such as searching and updating the information stored in the storage device.

[0051] The information processing device 20 has the following functions by executing the information processing program of this embodiment: Figure 4Specifically, the information processing device 20 includes a coin detection unit 21, a coin ID determination unit 22, a player detection unit 23, a player ID determination unit 24, a first association unit 25, a second association unit 26, a comparison unit 27, a recording unit 28, a rewrite control unit 29, and an update unit 30.

[0052] The game coin detection unit 21 obtains an image captured by the first camera 11 (hereinafter referred to as the "first image"), and detects a game coin group area including a game coin group from the first image. When the game coins 50 placed in the placement area 112 of the game table 110 are stacked in the placement area 112, the game coin detection unit 21 detects the area including the pile of placed game coins as the game coin group area (game coin pile area). Specifically, the game coin detection unit 21 detects a rectangular frame including a game coin group as the game coin group area.

[0053] The game coin detection unit 21 detects the game coin area corresponding to each game coin from the detected game coin group area. At this time, the game coin detection unit 21 can detect each game coin area using the center line 51 of the side of the game coin 50. That is, the game coin detection unit 21 can determine the position and size of the game coin area according to the position and length of the center line 51.

[0054] The game coin ID determination unit 22 obtains an image (hereinafter referred to as the "second image") captured by the second camera 12. In addition, the game coin ID determination unit 22 detects the game coin group area and the game coin area from the second image in the same manner as the game coin detection unit 21. The game coin ID determination unit 22 performs code recognition on the detected game coin area and interprets the code information of each game coin 50. Thus, the game coin ID determination unit 22 determines the game coin ID of each game coin area, and thus determines all the game coin IDs included in each game coin group area. At this time, the game coin ID determination unit 22 can detect the center line 51 of the game coin 50, and then perform code recognition in the area of ​​the detected center line 51.

[0055] As an alternative, the game coin ID determination unit 22 may be an RFID system that determines the game coin ID of the game coin placed in the placement area 112 through RFID. In this case, the game coin is built with an RFID tag storing the game coin ID of the game coin. The RFID system includes an antenna and a reader. The antenna is buried under the table 111 at a position corresponding to each placement area 112. The reader is connected to the antenna and obtains the game coin ID from the signal read by the antenna.

[0056] The game coin detection unit 21 determines the position of the detected game coin group area and determines the moment when the game coin group area is detected. On this basis or as a substitute, the game coin ID determination unit 22 determines the position of the game coin 50 whose game coin ID has been determined on the game table. In addition, the game coin ID determination unit 22 determines the moment when the game coin 50 whose game coin ID has been determined is placed on the game table.

[0057] The player detection unit 23 detects a player from the first image captured by the first camera 11. At this time, the player detection unit 23 detects the entire player including the face, upper body, wrist, and hand from the first image as the player, and extracts a skeleton model composed of the player's facial region, and key points of the upper body, wrist, and hand. The player detection unit 23 recognizes the facial region and skeleton model of the same player, and even a plurality of key points constituting the skeleton model, as belonging to one player.

[0058] The player ID determination unit 24 determines the player ID by performing facial recognition on the facial area of ​​the first image detected by the player detection unit 23. The player determined by the player ID determination unit 24 is registered in advance with an image of his face and is assigned a player ID. The player ID determination unit 24 determines which registered player the face in the facial area belongs to by using facial recognition technology. It should be noted that, if the result of facial recognition is that it is not determined which registered player is, the player ID determination unit 24 determines that the player in the facial area, that is, the player displayed in the player area, is an unregistered player.

[0059] The player may be registered by his player ID or by his facial information. In the case where the player is registered by the player ID, the player ID determination unit 24 determines the player ID of the player whose facial area is detected from the first image. In the case where the player is registered by facial information, the player ID determination unit 24 determines the facial information of the player whose facial image is detected from the first image. The facial information may be the facial image of the player or may be a feature amount extracted from the facial image of the player.

[0060] The first associating unit 25 associates the first game coin detected by the game coin detecting unit 21 with the player detected by the player detecting unit 23 as the player who places the first game coin. Specifically, the first associating unit 25 associates the hand of the player detected by the player detecting unit 23 with the game coin 50 detected by the game coin detecting unit 21 based on the positional relationship between the hand of the player detected by the player detecting unit 23 and the game coin 50 detected by the game coin detecting unit 21.

[0061] Figure 51 is a diagram of an example of association of the first association unit of an embodiment of the present invention. In this embodiment, from the same image such as the first image 90 captured by the first camera 11, the coin detection unit 21 detects the coin group areas c1 and c2, and the player detection unit 23 detects the players P1 and P2. The first association unit 25 determines the combination of the hands and the coin group areas based on the distance between the hands p11 and p21 of the players P1 and P2 detected by the player detection unit 23 and the coin group areas c1 and c2, and further determines the combination of the player and the coin group areas.

[0062] exist Figure 5 In the example, since the distance between the reference point cp1 of the game coin group area c1 and the hand p11 of the player P1 is less than the specified threshold, the first association unit 25 associates the game coin group area c1 with the player P1. In addition, since the distance between the reference point cp2 of the game coin group area c2 and the hand p21 of the player P2 is less than the specified threshold, the first association unit 25 associates the game coin group area c2 with the player P2. It should be noted that the reference point can be the center of the lower side of the rectangular frame constituting the game coin group area.

[0063] As described above, since the player detection unit 23 identifies the facial areas f1, f2 and the skeleton models sm1, sm2 including multiple key points of the same player as belonging to the same player, the first association unit 25 can associate the game coin group area with the facial area, the skeleton model and even each key point.

[0064] The second associating unit 26 associates the game coin ID of the game coin 50 determined by the game coin ID determining unit 22 with the player associated with the game coin 50 by the first associating unit 25. Specifically, the second associating unit 26 first determines that the game coin 50 detected by the game coin detection unit 21 and the game coin 50 whose game coin ID is detected and determined by the game coin ID determining unit 22 are the same game coin. To this end, the second associating unit 26 determines the game coin 50 located at the same position as the same game coin 50 based on the relationship between the position of the game coin 50 detected by the game coin ID determining unit 22 in the second image and the position of the game coin 50 detected by the game coin detection unit 21 in the first image.

[0065] More specifically, the second associating unit 26 converts the position of the game coin group area detected by the game coin detection unit 21 in the first image into the position in the second image, thereby determining the game coin group area located at the same position as the same game coin 50. Alternatively, as an alternative, the second associating unit 26 may convert the position of the game coin group area detected by the game coin ID determination unit 22 in the second image into the position in the first image, thereby determining the game coin group area located at the same position as the same game coin 50. Alternatively, the second associating unit 26 may convert the position of the game coin group area detected by the game coin detection unit 21 in the first image and the position of the game coin group area detected by the game coin ID determination unit 22 in the second image into a coordinate space common to both, thereby determining the game coin group area located at the same position as the same game coin 50.

[0066] In this way, the second association unit 26 determines the game coins 50 located at the same position as the same game coins 50 based on the position determined by the game coin detection unit 21 and the position determined by the game coin ID determination unit 22. However, instead, the second association unit 26 may determine the game coins 50 placed on the game table 110 at the same time as the same game coins 50 based on the time when the game coins are detected by the game coin detection unit 21 and the time when the game coins 50 are determined by the game coin ID determination unit 22.

[0067] The second associating unit 26 associates the coin ID of the coin determined by the coin ID determining unit 22 with the player associated with the coin through the first associating unit 25. Specifically, when the player is registered by the player ID, the second associating unit 26 associates the coin ID of the coin determined by the coin ID determining unit 22 with the player ID of the player associated with the coin through the first associating unit 25. Furthermore, when the player is registered by facial information, the second associating unit 26 associates the coin ID of the coin determined by the coin ID determining unit 22 with the facial information of the player associated with the coin through the first associating unit 25.

[0068] The recording unit 28 records a combination of the game coin ID of the game coin 50 and the image of the player associated with the game coin ID of the game coin 50 through the second association unit 26. At this time, as described later, the recording unit 28 can also record the game coin ID and the player ID of the player associated therewith, or can record the game coin ID and the facial information of the player associated therewith. As in the present embodiment, the recording unit 28 records only the image of the player in association with the game coin ID determined by the game coin ID determination unit 22, and does not record the player ID used to determine the player associated with the game coin ID, thereby not recording the player's personal information and protecting the player's privacy.

[0069] The game coin ID of the game coin 50 is stored in the database 40 in association with the owner of the game coin 50. Specifically, when the player is registered by the player ID, the database 40 stores the game coin ID of the game coin 50 in association with the player ID of the player who is the owner of the game coin 50. Alternatively, when the player is registered by facial information, the database 40 stores the game coin ID of the game coin 50 in association with the facial information of the player who is the owner of the game coin 50.

[0070] The comparison unit 27 compares the owner associated with the game coin ID of the game coin 50 in the database 40 and the player associated with the game coin ID of the game coin 50 through the second association unit 26. When the owner associated with the game coin ID of the game coin 50 in the database 40 and the player associated with the game coin ID of the game coin 50 through the second association unit 26 are inconsistent, the comparison unit 27 outputs a signal indicating inconsistency.

[0071] Specifically, when a player is registered by a player ID, the comparison unit 27 compares the player ID associated with the game coin ID of the game coin 50 in the database 40 with the player ID determined by the player ID determination unit 24 for the player associated with the game coin ID of the game coin 50 through the second association unit 26. In this case, when the player ID of the owner associated with the game coin ID of the game coin 50 in the database 40 and the player ID of the player associated with the game coin ID of the game coin 50 through the second association unit 26 are inconsistent, the comparison unit 27 outputs a signal indicating inconsistency.

[0072] In the case where the coin ID of the game coin 50 is associated with the facial information of the owner of the game coin 50 and is stored in the database 40, in addition to or instead of the above specific example, the comparison unit 27 compares the facial information associated with the coin ID of the game coin 50 in the database 40 with the facial information extracted from the image of the player associated with the game coin through the second association unit 26. In this case, when the facial information associated with the coin ID of the game coin 50 in the database 40 and the facial information extracted from the image of the player associated with the game coin 50 through the second association unit 26 are inconsistent, the comparison unit 27 outputs a signal indicating inconsistency.

[0073] When a player different from the original owner of a game coin 50 on the game table 110 operates the game coin 50, the above-mentioned function of the comparison unit 27 can output a signal indicating inconsistency, thereby issuing a warning of such inconsistency.

[0074] When the comparison unit 27 determines that the owner associated with the game coin ID of the game coin 50 in the database 40 and the player associated with the game coin ID of the game coin through the second association unit 26 are inconsistent, the rewrite control unit 29 rewrites the owner associated with the game coin ID of the game coin in the database 40 to the player associated with the game coin ID of the game coin through the second association unit 26.

[0075] In the case where the game coin 50 is incorrectly associated with a player, the situation can be corrected and associated with the correct player through the rewrite control unit 29. In addition, in the case of determining that the game coin ID is not associated with any player, the rewrite control unit 29 rewrites the player associated with the game coin ID through the second association unit 26 as the owner of the game coin ID.

[0076] When a player wins the game and receives payment of game coins 50 from the dealer, the owner of the game coins involved in the payment (hereinafter referred to as "payment game coins") should be changed from the dealer or the casino to the player who won the game. Therefore, the update unit 30 rewrites the owner associated with the game coin ID of the payment game coin paid by the dealer in the database 40 to the player associated with the payment game coin through the second association unit 26. To this end, the first camera 11 and the second camera 12 shoot when the game coin 50 is paid, the first association unit 25 associates the game coin group area of ​​the payment game coin with the player who wants to take the payment game coin, and the update unit 30 updates the database 40 according to the association.

[0077] Alternatively, the updating unit 30 rewrites the owner associated with the coin ID of the payout coin paid by the dealer in the database 40 to the player associated with the coin 50 moved from the placement area 112 together with the payout coin through the second associating unit 26. Thus, the coin ID of the payout coin 50 is stored in the database 40 in association with the player ID of the player who received the coin 50.

[0078] It should be noted that an RFID tag storing the game coin ID is built into the game coin 50. When the game coin ID determination unit 22 reads the game coin ID from the RFID tag of the game coin 50 in the placement area 112, the game coin ID can be determined by reading the RFID tag of the payment game coin in the payment placement area 112, and the player ID that should be associated with the game coin ID can be updated.

[0079] In addition, in the above-mentioned embodiment, the first camera that generates the first image by shooting and the second camera that generates the second image by shooting are different cameras, but these can also be one camera. In this case, both the first image and the second image can be generated by the one camera. And in this case, when shooting the first image and when shooting the second image, the shooting conditions (angle of view, resolution, shooting direction, etc.) can be changed.

[0080] As shown above, in the game monitoring system 100 of this embodiment, the first associating unit 25 associates the game coin 50 (game coin stack) on the game table 110 detected by the game coin detection unit 21 from the first image with the player detected by the player detection unit 23 from the first image, and the game coin ID determination unit 22 determines the game coin ID of the game coin 50 based on the second image, thereby, the second associating unit 26 associates the player with the game coin ID. In this way, it is possible to determine which player's game coin 50 on the game table 110 belongs to, and it is possible to perform game management such as cheating detection and customer rating.

[0081] It should be noted that, as described above, the method for determining the game coin ID of the game coin 50 on the game table 110 is not limited to the method using an image, and may also be a method using an RFID tag and an RFID reading system. Since the game coin can be associated with the player who operates the game coin through the above-mentioned embodiment, for example, even if the player places the game coin 50 in the placement area 112 other than the placement area set in front of his own player position, or for the game coin 50 placed by the later placer who is not seated at the player position, it is possible to determine which player has placed these game coins based on the image.

[0082] It should be noted that the information processing device 20 can also identify the position, type and number of game coins 50 placed on the game table 110 based on the first image or the second image, or by embedding an RFID tag that at least stores information about the type of the game coin 50 in the game coin 50, burying multiple antennas in the game table 110, and reading the RFID tags of the game coins 50, thereby identifying the position, type and number of the game coins 50 placed on the game table 110.
