Abstract
A light distribution control device controls a high beam emitter capable of dividing a high beam irradiation area into a plurality of areas and includes processing circuitry configured to; detect whether or not an irradiation target to be irradiated with a high beam or a light shielding target to be shielded from the high beam is present in the high beam irradiation area; determine a light shielding region for shielding the light shielding target when the light shielding target is detected; calculate an optical axis adjustment amount for adjusting a direction of an optical axis of the high beam emitter in such a manner that the irradiation target is out of the light shielding region when the irradiation target is included in the light shielding region; and control the optical axis of the high beam emitter on a basis of the optical axis adjustment amount.
