Abstract:

Provided are an information processing device, an information processing method, a program, and an information storage medium, for which, in comparison with the prior art, the precision in determining whether an object is in contact with a photographic subject is improved. A frame image acquisition unit (32) acquires multiple frame images which include a photographic subject region in which the image of a photographic subject appears, and each of which has been photographed at a different time. For each frame image a photographic subject sub-region identification unit (38) identifies multiple photographic subject sub-regions, each of which is a portion of the respective photographic subject region and has a different position than that of the other sub-regions in the photographic subject region. On the basis of an image characteristic amount for the image occupying the corresponding photographic subject sub-region in each frame image, a sub-region characteristic amount identification unit (40) identifies a sub-region characteristic amount indicating the variation in the image characteristic amount for the image occupying the photographic subject sub-region. On the basis of the relationships between the sub-region characteristic amounts associated with each of the multiple photographic subject sub-regions, a contact determination unit (42) determines whether an object is in contact with the photographic subject.
