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 464 extracts an area in that a game medium is reflected from a captured image 462B in that the game medium is reflected, a location part 465 locates a characteristic local area in the extracted area, and a fitting part 466 fits an ellipse to the local area and generates ellipse information regarding the ellipse as a feature amount. A determination part 467 compares a feature amount generated by the fitting part 466 with a standard feature amount generated regarding a regular game medium to determine whether or not the game medium included in the captured image 462B is regular.SELECTED DRAWING: Figure 59 |
