1. A merchandise specification system for specifying merchandise displayed on a display shelf, comprising:
- a keystone correction processing unit that performs a keystone correction process on photographed image information obtained by photographing the display shelf to generate front-facing image information; and
a merchandise identification information specification processing unit that specifies merchandise on a face in the front-facing image information, whereinthe keystone correction processing unitprojects vertexes used in the keystone correction process on first photographed image information onto second photographed image information, based on correspondence between the first photographed image information and the second photographed image information, andexecutes the keystone correction process on the second photographed image information based on the projected vertexes to generate front-facing image information, andthe merchandise identification information specification processing unitcompares image information of a face in second front-facing image information with image information of a face within a predetermined range of first front-facing image information corresponding to the face to specify merchandise identification information of merchandise on the face in the second front-facing image information.
