CONTROLLER FOR LIGHTING CONTROL, VEHICLE LAMP SYSTEM

To make it possible to grasp the road surface condition more reliably when the road surface on which the irradiation pattern (101) is formed is captured by a camera (11). A controller (10) for lighting control installed in a vehicle (100) that is equipped with a camera (11) that captures the surroundings of the vehicle, a monitor (16) that displays images captured by the camera (11), and an irradiation unit (12) capable of irradiating light on a road surface within a range that can be captured by the camera (11), and in which the controller (10) performs operation control of the irradiation unit (12), where the controller (10) performs operation control of the irradiation unit (12) so that it prevents the irradiation unit from performing light irradiation during each intermittently occurring capturing period (ts) of the camera (11), and causes the irradiation unit (12) to irradiate light during a non-capturing period (tm) between the capturing periods.
