PROBLEM TO BE SOLVED: To provide an image processor equipped with a distortion correction processing part for effectively using original data to perform a distortion correction processing, and for efficiently and effectively outputting a corrected image to an image output range, and being adaptive even to bobbin-shaped distortion, barrel-shaped distortion, and soldier's helmet-shaped distortion. SOLUTION: The image processor having a distortion correction processing part 8 includes a distortion correction range calculating part 12 for calculating an input image range necessary for the distortion correction processing part 8 to perform distortion correction processing. Thereby, a corrected image(output image) acquired by the distortion correction can be outputted to an image output range neither excessively or insufficiently. Thus, distortion correction processing to effectively use input(photographic) image data being original data can be performed, and effective distortion correction processing can be performed even to bobbin-shaped distortion, barrel-shaped distortion or soldier's helmet-shaped distortion.
