In order to perform image registration of first and second images using block matching wherein the first image is divided into a plurality of blocks, the plurality of blocks are classified into a plurality of block groups, using block matching results, such that the blocks classified into the same block group are considered to produce similar position correcting parameters. A plurality of position correcting parameters is determined with each of the plurality of block groups specified above. Thereafter, most appropriate position correcting parameters are determined, among the position correction parameters determined by referring to said first and second images.
