The arrangements of feature points are computed based on feature points acquired from checking target images. The feature amount having invariants as elements regarding a geometrical transformation is generated for each of the checking target images based on a computed result. And when checking whether or not the feature point arrangements of the checking target images are the same feature point arrangements by using the feature point amounts of the checking target images, at least each of the feature point arrangements that are bases for generating the feature amounts is stored, and a parameter regarding the geometrical transformation is computed based on the feature point arrangements of the checking target images. By utilizing the computed parameter regarding the geometrical transformation, whether or not the feature point arrangements of the checking target images are the same feature point arrangements is checked. |
