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.

Abstract: A vehicle periphery monitoring apparatus displays a detection line on a display unit, with side portions of the detection line positioned on far-off spots that are farther than a spot on which a center portion of the detection line is positioned. In addition, based on the distance of the respective spots on which the portions of the detection line are positioned, the apparatus includes a parameter table that defines different parameters for a short distance portion, a middle distance portion, and a long distance portion of the detection line. The apparatus detects a moving object based on an actual-detected brightness change of a pixel along the detection line and a predefined brightness change of a pixel along the detection line that is defined by the parameter of the parameter table.
