Abstract
An operation control map of a white line detection apparatus, including a white line detection portion that detects a white line on a road based on a captured image of the road surface, that references the operation control map to determine whether to allow operation of the white line detection portion. The operation control map includes a region in which operation of the white line detection is allowed, and a region in which operation is not allowed, based on the gain of a road surface image signal and the temperature of a road surface imaging portion. The allowed region is set if the reduced accuracy of white line detection, due to the thermal noise generated in the solid-state imaging sensor, falls within an acceptable range, and the disallowed region is set if the reduced accuracy of white line detection falls outside of the acceptable range.
