Abstract: The value of a stereo vision parameter for an immediately preceding frame is subtracted from the value of the stereo vision parameter for a current frame to obtain a differential value d. If d<?? (lower limit value), the differential value d is set to ??, and if d>? (upper limit value), the differential value d is set to ?. If the differential value d is within the range of ?? to ?, it is left as it is without being changed. The thus set differential value d is added to the value of the stereo vision parameter for the immediately preceding frame, and the resulting value is set as the stereo vision parameter for the current frame. By thus setting the stereo vision parameter, a limit is imposed upon abrupt change of the stereo vision parameter for the current frame.
