PROBLEM TO BE SOLVED: To suppress increase in a device size in a device correcting optical distortion in a first and second image frames having parallax differences as to an identical subject, and achieve increase in speed of optical distortion correction processing.SOLUTION: When the optical distortion correction processing of a correction target pixel in the first image frame cannot be executed by pixel data stored in a line memory 182 in a process of executing the optical distortion correction processing of the first image frame, a distortion correction unit 183 stores first coordinate information pertain to the correction target pixel in a coordinate storage memory 186. The distortion correction unit 183 controls a DMA controller 181 so as to store correction pixel data of a correction target pixel in the second image frame corresponding to the correction target pixel in the first image frame, in the line memory 182, on the basis of the first coordinate information stored in the coordinate storage memory 186 in a process of executing the optical distortion correction processing of the second image frame. |
