Abstract

As to N images captured at different focus positions, which are arrayed in order of focus positions, N/2 images are set as feature point extraction images so that at least one of two adjacent images becomes a feature point extraction image; corresponding points corresponding to a feature point, extracted from the feature point extraction image, are searched for from the other images; a correction parameter, with which corresponding positions of the N images are matched, is calculated from a positional relation of the feature point and the corresponding points; and, with an image whose view angle is the smallest among the N images as a reference, the other images are corrected.
