<P>PROBLEM TO BE SOLVED: To provide an image processor for performing correct movement estimation without increasing a range for measuring a cross-correlation value. <P>SOLUTION: This image processor is constituted of a cross-correlation calculation part 12, a self-correlation calculation part 14, a solution candidate listing part 16, a correction value calculation part 18, and a minimum retrieval part 20, performs block matching in an object image to obtain a self-correlation line, performs block matching of the object image and a reference image to obtain a cross-correlation value, and performs fitting of the self-correlation line to solution candidate positions in the cross-correlation values to obtain a true solution. <P>COPYRIGHT: (C)2009,JPO&INPIT |
