PROBLEM TO BE SOLVED: To provide an image processor capable of performing alignment of a plurality of photographic images with high accuracy regardless of a light emission characteristic of an object that is a reference of the alignment, and a photographic condition of the object. SOLUTION: An area pixel data integration part 130 relatively shifts an arithmetic area outputted from an arithmetic area setting part 102 to a filter image 101, and sequentially calculates area integration data wherein all luminance values of the arithmetic area are added up in each shift position. A shift amount calculation part 104 finds a maximum value from the area integration data of each the shift position, and calculates the shift position corresponding to the maximum value as a shift amount for the alignment. A position correction part 105 shifts the filter image 101 on the basis of the calculated shift amount, and outputs it as an output image 106. COPYRIGHT: (C)2006,JPO&NCIPI
