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