Abstract
An image processing apparatus is provided with: an image taking device (19a, 19b) for taking an image on a side of a movable body and outputting an image signal corresponding to the taken image; a movement vector detecting device (18, 24) for detecting a movement vector for each area of the image taken by the image taking device, on the basis of the image signal while the movable body is moving; and a distance calculating device (18, 25) for judging a spatial changing rate of a magnitude of the detected movement vector and calculating the distance to a road edge on the basis of the spatial changing rate.
