VEHICLE PERIPHERY MONITORING APPARATUS
First Claim
1. A vehicle periphery monitoring apparatus comprising:
- a detection unit detecting a brightness change of a pixel along a plurality of detection lines, the plurality of detection lines extending along a right-left axis in an image captured by an in-vehicle camera as an image of a vehicle periphery; and
a moving object determination unit determining a presence of the moving object based on the brightness change of the pixel detected by the detection unit and a parameter for evaluating the brightness change to determine whether the brightness change of the pixel along the detection lines is caused by the moving object, whereinthe moving object determination unit changes a determination condition for determining whether the moving object is present based upon a number of the detection lines along which the brightness change is detected by the detection unit, such that as the number of detection lines that have the brightness change decreases, the harder it is to satisfy the determination condition for determining that the moving object is present.

Abstract
A vehicle periphery monitoring apparatus detects the presence of a moving object along a vehicle periphery. The apparatus sets multiple detection lines along a horizontal axis of an image captured by a camera, and detects a brightness change of a pixel along the detection lines. With reference to the brightness change detected along the detection line and a parameter for determining whether such brightness change is caused by the moving object, the apparatus determines the presence of the moving object. In addition, the apparatus changes a determination condition for determining the moving object such that as the number of detection lines along which the brightness change is detected decreases, the harder it is to satisfy the determination condition for determining that the moving object is present.
