Abstract

A vehicle light source detection device in a light beam control system detects a position of a light source appeared and detected in captured image data. The device calculates a gradient of a road on which the own vehicle is running. The vehicle light source detection device estimates a vanishing point in the captured image data on the basis of the detected gradient of the road. The device further increases a reliability value of the detected light source when the point of the detected light source more approaches the vanishing point. When the reliability value of the detected light source is not less than a predetermined reference value, the device determines that the detected light source is a head lamp of an oncoming vehicle, and adjusts an irradiation range of the light beam of the head lamps of the own vehicle to avoid the oncoming vehicle.
