Abstract

An image processing device comprises a region dividing unit which divides a captured image obtained by a camera unit into a plurality of regions, and an image compressing unit which compresses each of region images obtained by the division by the region dividing unit while changing the compression rate according to the distance from a predetermined point in the captured image to each of the region images and the distance from the camera unit to a target included in each of the regions. For example, the image compressing unit compresses the region image having a larger angle from the optical axis at a larger compression rate, thereby achieving compression in which the amount of data in low-quality regions is greatly reduced and the quality of high-quality regions is maintained.
