PROBLEM TO BE SOLVED: To readily identify a player before and after leaving his or her seat. SOLUTION: A CCD camera is installed at a call lamp provided at each game machine to photograph the player from the front. The captured image (a) of the player before leaving his or her seat is temporarily stored in a memory. This stored image is compared with an image captured again after leaving his or her seat. In the comparison process, the captured images before and after leaving his or her seat are divided into a plurality of blocks of data as shown by broken lines in figure. Data corresponding to a block B1 in the image (a) is stored in an image storage memory, and the stored data is compared with data corresponding to a block B1' in the image (b). The whole of photographed images before and after leaving his or her seat is successively subjected to the comparison process to determine the identity. When the ratio of the number of blocks having identity to the total number of blocks is a prescribed percentage or more, it is determined that the player before and after leaving his or her seat has identity.
