Claim Text:
1. An on-vehicle image processor comprising: an imager mounted on a vehicle, which observes surroundings of the vehicle and captures an image including at least a road surface; a candidate white-line area detector which a parking-frame similitude calculator which calculates a parking-frame similitude according to a brightness distribution of surroundings of the first pixels of the candidate white-line area and a brightness distribution of surroundings of the second pixels, the parking-frame similitude being a similitude when each of the candidate white-line areas is assumed to form a parking frame; and a parking frame detector which detects a parking frame according to the position of the candidate white-line area, the parking-frame similitude, and an expected size of a parking frame in the image, wherein the parking-frame similitude calculator decreases the parking-frame similitude of the candidate white-line area when the brightness distributions of the surroundings of the first pixels and the second pixels of the candidate white-line area satisfy a certain condition.
