Abstract
A relative direction relationship is acquired between first and second input area images of a particular person taken from different directions. The particular person is identified by comparing a feature of the first input area image with a feature of a first one of registered area images of the particular person or another person taken from at least three directions, comparing a feature of the second input area image with a feature of a second registered area image of the same person as the person of the first registered area image, and determining whether the person in the first and second input area images is the same person in the first and second registered area images. The first and second registered area images are selected such that the relation between the first and second registered area images is similar to the relation between the first and second input area images.
