1. A table game management system used at a game table for playing games by betting chips and utilizing deep learning, the game table management system comprising:
a camera configured to obtain a single captured image of a chip stack placed in a plurality of betting areas arranged in a two-dimensional pattern in a shooting and angle-of-view directions so that a top and sides of the chip stack are captured by shooting a predetermined area including the plurality of betting areas of the game table from diagonally above, wherein:
in the single captured image, the chip stack include chips that receive different amounts of light or chips that are partially hidden due to blind spots,
the chips comprising the chip stack are identifiable as to type by at least color information or pattern of the sides, and
the camera is configured to capture a plurality of chip stacks at different distances from the camera in the single captured image; and
a control device configured to:
based on the single captured image, determine a position in the two-dimensional pattern of the chip stack wagered on the game table, the single captured image showing the top and sides of the chip stack obtained by capturing the chip stack, including the plurality of betting areas, from diagonally above the betting area of the game table with the camera,
determine the type and number of chips comprising the chip stack based on the color information or pattern of at least the sides of the chips in the single captured image, and
by extracting features and performing image recognition on the single captured image in which the color information or pattern appears, recognize targets including chips that receive different amounts of light or chips that are partially hidden due to blind spots in the single captured image, and
wherein the game table has a plurality of player positions arranged horizontally, and each player position has a plurality of betting areas laid out vertically, resulting in the plurality of betting areas being laid out on a two-dimensional plane.
