Headlight control apparatus for automobile

Abstract

The present invention provides a headlight control apparatus which suppresses a feeling of strangeness given to a driver of an own vehicle by hunting due to reflector light while preventing a preceding vehicle (502) and an on-coming vehicle (501) from being dazzled, based on a video image obtained by a camera (101). The headlight (104) is controlled by detecting the position of a light spot in the image captured by the camera (101) to perform irradiation with a pattern which reduces the light quantity of a certain area above the detected light spot. Thereby, even if hunting occurs due to the reflector light, the irradiation light quantity of an entire irradiation area of the headlight does not vary, but only the irradiation light quantity for a partial area above a reflector varies, and therefore, the feeling of strangeness given to the driver can be suppressed.
