On-board device // 2640683
FIELD: physics.SUBSTANCE: on-board device comprises an accumulation detection module, a selection module, and a deletion determination module. The accumulation detection module detects the accumulation that settles on the photographic lens from the photographic image output from the on-board camera. The selection module selects an accumulation deletion module using the first method. The deletion determination module performs the determination based on the photographic image as to whether or not the photographic lens is removed from the photographic lens by a deletion operation performed by the accumulation removal unit using the first method. If the removal definition module specifies that the accumulation is not removed from the photographic lens, the selection module selects the accumulation deletion module, applying the second method that is different from the accumulation deletion module using the first method, based on the number of times when the delete operation is performed by activating the accumulation deletion module, applying the first method.EFFECT: optimum washing of the photographic lens of the on-board camera.6 cl, 15 dwg
