Abstract

A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyzes the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.

First claim

What is claimed is:

1. A fraud detection system in a casino having a plurality of gaming tables, comprising:
a game recording apparatus which records a progress of a game played on the gaming table as an image;
an image analyzing apparatus which performs image analysis on the image of the recorded progress of the game;
a win/lose result determining apparatus which determines a win or lose result of each game on the gaming table; and
a control device which detects fraud practiced on the gaming table by using a result of the image analysis by the image analyzing apparatus and the win or lose result determined by the win/lose result determining apparatus,
wherein the control device recognizes a position, type, and number of the chips wagered by each player through the image analyzing apparatus and recognizes a total amount of chips in a chip tray of a dealer of the gaming table, performs addition/subtraction calculation of an increased/decreased amount of the chips in the game calculated from the position, type, and number of the chips wagered by all the players 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 in the chip tray before the settlement of each game and compares a correct total amount of the chips in the chip tray after end of the game and settlement and an actual total amount of the chips in the chip tray at the time of the end of the game obtained through the image analyzing apparatus to determine whether or not there is difference between the correct total amount and the actual total amount.

2. The fraud detection system according to claim 1 , wherein the control device recognizes the position, type, and number of the chips wagered by each player through the image analyzing apparatus, 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, and compares the correct total amount of the chips in the chip tray added with the increased amount of the chips in the chip tray 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 in the chip tray to determine whether or not there is difference between the correct total amount and the actual total amount.

3. The fraud detection system according to claim 2 , wherein, in the case where the control device compares the correct total amount of the chips in the chip tray added with the increased amount of the chips in the chip tray 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 in the chip tray 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 after the end of the game and the settlement and the actual total amount of the chips in the chip tray obtained through the image analyzing apparatus 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.

4. The fraud detection system according to claim 2 , wherein the chip tray is provided with a collection chip tray where the chips wagered by the lost player are collected and temporarily stored, and the image analyzing apparatus and the control device compare the correct amount of chips in the collection chip tray calculated from the position, type, and number of the chips wagered by the lost player and the actual total amount of the chips in the collection chip tray to determine whether or not there is difference between the correct total amount in the collection chip tray and the actual total amount.

5. The fraud detection system according to claim 1 , wherein acquisition of the actual total amount of the chips in the chip tray after the end of the game and the settlement through the image analyzing apparatus is performed any one of: 1) the time when redemption for the winning chips is ended; 2) the time when the cards used in the game are collected to be discarded into a discard area 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 representing win or lose is returned to an initial state.

6. The fraud detection system according to claim 1 , wherein, when the control device determines that there is difference that the recognized actual total amount of the chips in the chip tray of the dealer of the gaming table 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 is configured to be capable of allocating indexes or time points to the acquired images or reproducing the images specified with a collection scene or a redemption scene of the chips so that the record of the game where the difference occurs can be analyzed in the game recording apparatus.

7. The fraud detection system according to claim 1 , wherein the image analyzing apparatus or the control device has a 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, information on the type, number, and position of the wagered chips can be obtained.

8. The fraud detection system according to claim 1 , wherein the control device has a structure capable of:
1) recognizing the position, type and number 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 statistical data to extract a strange situation; and
2) 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 statistical data to extract a strange situation.

9. The fraud detection system according to claim 1 , wherein the control device performs comparison determination as to whether or not the recognized amount of chips in the chip tray of the dealer of the gaming table is increased or decreased according to the paid amount of the chips corresponding to the exchanged cash or the paid amount of the cash corresponding to the exchanged chips after the exchange of cash and chips.

10. The fraud detection system according to claim 9 , wherein the control device is further provided with database storing history of exchange of cash and the chips, and by referring to the database in unit of a predetermined time or a day, and the control device is capable of performing comparison determination as to whether or not the recognized amount of the chips in the chip tray of the dealer of the gaming table is increased or decreased according to the paid amount of the chips corresponding to the exchanged cash or the total amount of the paid amount of the cash corresponding to the exchanged chips.

11. The fraud detection system according to claim 1 , wherein the control device is capable of specifying a player of the play position extracted as the difference or the strange situation through the image analyzing apparatus.
