PROBLEM TO BE SOLVED: To provide a game machine capable of detecting a fraudulent act for playing a game by allowing use of a regular game medium to be misunderstood.SOLUTION: An extraction part 564 extracts an area in which a game medium is reflected from a captured image 562B in that the game medium is reflected, and an area division part 565 divides an area in that a branch medium is reflected into a plurality of divided areas, based on entropy of brightness histogram. A feature amount acquisition part 566 acquires a feature amount based on the size or the like of the divided areas, and a determination part 567 compares the acquired feature amount with a standard feature amount generated regarding a regular game medium to determine whether or not the game medium included in the captured image 562B is regular.SELECTED DRAWING: Figure 78 |
