An image processing device includes a first camera that captures the periphery of a vehicle, specific region extracting units that extract regions, each of which is closer to the edge of an image than to the center of the image, as specific regions, and a movement amount calculating unit that calculates the amount of movement of the vehicle on the basis of image information in a plurality of specific regions. Therefore, it is possible to process only the first specific region and the second specific region of the captured image and thus effectively perform image processing.
