Abstract:
1. An image processing apparatus for correcting the positional offset between an input image and a reference image, comprising: storage means for storing information about the reference image, including a reference position; area information specifying means for obtaining information about a plurality of areas included in the input image, the information including left end coordinates and upper end coordinates of the plurality of areas; target position setting means for obtaining a leftmost end coordinate from among the left end coordinates of the plurality of areas included in the information obtained by said area information specifying means, obtaining an uppermost end coordinate from among the upper end coordinates of the plurality of areas, and setting the obtained leftmost end coordinate and the uppermost end coordinate as a target position; calculating means for specifying information about the reference image in accordance with the input image from said storage means, and calculating the positional offset between the reference position included in the specified information and the target position set by said target position setting means; and correcting means for correcting positions of a plurality of areas included in the input image by using the positional offset calculated by said calculating means.
