Abstract

An automatic vehicle head lamp dimming system which includes an optical system and an imaging processing system. The optical system is configured to discriminate between head lamps and tail lamps and focus the light rays from the head lamps and tail lamps on different portions of a pixel sensor array. The optical system as well as the image processing system provides for relatively increased discrimination of head lamps and tail lamps of other vehicles and also enables the high beam head lamps of the control vehicle to be controlled as a function of the distance as well a s horizontal angular position of other vehicles relative to the controlled vehicle.</SDOA B>
