LIGHT DISTRIBUTION CONTROL APPARATUS

A light distribution control apparatus includes an imaging device capable of capturing an image of a front vehicle existing in front of an own vehicle, a headlight capable of irradiating a front region of the own vehicle, and a control unit capable of executing light distribution control for controlling light distribution of the headlight so that a predetermined first region including the front vehicle and a predetermined second region other than the first region are irradiated with different illuminances based on the captured image obtained by capturing an image of the front region of the own vehicle. The control unit sets an illuminance irradiated in the first region to be less than an illuminance irradiated in the second region, and sets an area of the first region based on a position in a lateral direction of the front vehicle in the captured image.
