8. The system according to claim 1 , wherein the at least one processor is configured to perform image recognition using a learning function or an artificial intelligence function for the recognition of the positions, types, and numbers of the chips wagered even in a situation where a part of the chips placed on the gaming table is concealed due to a blind spot of the camera.
9. The system according to claim 1 , wherein the at least one processor is configured to:
based on the positions, types, and number of the chips wagered by the player or in connection with the player position and the determined outcome, calculate a collecting amount of chips corresponding to losing chips of the chips wagered by the player or in connection with the player position and a payment amount of chips corresponding to winning chips of the chips wagered by the player or in connection with the player position; and
determine whether an amount of the chips stored in a dealer chip tray of the gaming table, after settlement of the game, increases or decreases according to the calculated collected amount and the calculated payment amount.
10. The system according to claim 1 , wherein:
the at least one processor is configured to extract an unusual situation; and
the extraction one of:
is based on the obtained amounts of chips;
is based on an amount of the chips wagered by the player or in connection with the player position and the outcome of the game; and
is performed respectively for each of a plurality of playing positions based on a relationship between an amount of chips wagered when losing at the respective playing position and an amount of chips wagered when winning at the respective playing position.
11. The system according to claim 10 , wherein the at least one processor is configured to extract the unusual situation based on the obtained amounts of chips.
12. The system according to claim 10 , wherein the at least one processor is configured to extract the unusual situation based on the amount of the chips wagered by the player or in connection with the player position and the outcome of the game.
13. The system according to claim 10 , wherein the at least one processor is configured to perform the extraction respectively for each of the plurality of playing positions based on the relationship between the amount of chips wagered when losing at the respective playing position and the amount of chips wagered when winning at the respective playing position.
14. The system according to claim 10 , wherein the at least one processor is configured to identify a player for which the unusual situation is extracted.
15. The system according to claim 10 , wherein the at least one processor is configured to output a warning notifying of a presence of a player for which the unusual situation has been extracted.
16. The system according to claim 10 , wherein the at least one processor is configured to extract the unusual situation by comparing the outcome with statistical data.
17. The system according to claim 1 , wherein the at least one processor is configured to identify whether above a predefined threshold amount has been won by the player or in connection with the player position.
