PROBLEM TO BE SOLVED: To provide an image processor of a small circuit scale and a low electric power consumption capable of correcting distortion and chromatic aberration. SOLUTION: This image processor for processing an electronic image data constituted of a plurality of components imaged by an optical system is provided with a distortion correcting processing part having a single distortion correction coefficient calculating part 22a for calculating a distortion correction coefficient for correcting a distortion aberration caused by the optical system in every component, based on a distance from the distortion center position, distortion correction circuits 7A1, 7B1, 7C1 for distortion-correcting the image data of the every component, using the distortion correction coefficient calculated by the distortion correction coefficient calculating part 22a, and a grant synchronization circuit 27 for conducting control to output a permission signal e_grant to the distortion correction coefficient calculating part 22a after distortion correcting processing start request signals trok from all the distortion correction circuits 7A1, 7B1, 7C1 are all present, and to start distortion correcting processing in all the distortion correction circuits 7A1, 7B1, 7C1.
