Abstract
A vehicle detection apparatus detects oncoming vehicles, and the illumination angle of the headlight is changed downwardly when oncoming vehicles are detected. When detecting the oncoming vehicles, the vehicle detection apparatus detects brightness or area for the every light source in an acquired image repeatedly, and detects as a variable light source any light source of which brightness or area changes within a reference time beyond a predetermined variation reference value. Then, when a variable light source is detected, it is determined that vehicles exist in the acquired image.
