description A light distribution control device (6) controls, using an image (IMG) based on an imaging device (4) for imaging an area in front of a vehicle, a variable light distribution lamp (2) capable of irradiating the area in front with a variable intensity distribution visible light beam (L1). The light distribution control device (6) defines a light irradiating the area in front corresponding to a predetermined high-brightness pixel (202-206) included in the image (IMG) to be a subject light, adjusts an illuminance of the subject light so that a brightness value presented by the high-brightness pixel (202-206) gradually approaches a predetermined target low brightness, and, during adjustment, varies the illuminance by a smaller amount of change when increasing the illuminance than when decreasing the illuminance.
