Abstract
An image collation device capable of obtaining a high collating precision with a reduced amount of searches is constituted as follows. The image collation device includes an input unit which receives data representing an image A and data representing an image B, and a processing unit which determines whether or not a possibility that a center region of the image A which is a portion thereof matches with any portion of the image B is below a threshold value T(2) and determines whether or not the image A matches with the image B when it is determined the possibility that the center region matches with the any portion of the image B is equal to or more than the threshold value T(2).
