An image collation apparatus has stored therein first image (1a) (registered fingerprint) beforehand. Regarding second image (1b) (fingerprint to be collated) that is input when collation is performed, the apparatus thereby determines the identicalness between this second image and the first image. At this time, the apparatus (3) defines with respect to the first image a plurality of regions each having a predetermined positional relationship with respect thereto. The apparatus (4) searches from the second image an image region having a maximum correlation with the image of each of the respective defined regions. The identicalness (5) between the first image and the second image is determined according to the difference between the positional relationship of each of the respective image regions defined on the first image and the positional relationship of the maximum correlation region that comprises been searched out on the second image. |
