Abstract
A road surface reflection detecting apparatus includes a road recognition unit for recognizing a road in a picture taken by a camera of a road existing in front of a vehicle. A road surface reflection detection unit extracts a picture from the road recognized by the road recognition unit and determines the degree of reflection of light from the surface of the road based on the picture extracted from the road. The picture includes the reflection of light beam radiated from vehicle headlights. If the reflection is determined to be high, the direction or intensity of the light beam from the vehicle headlights is regulated.
