adjusting, by the controller, a number of times that washer fluid is dispensed through a washer fluid nozzle and a number of times that an imaging device is inserted into a housing and then extended therefrom based on current driving state of a vehicle or a vehicle speed;
wherein the housing is rotatably coupled to a base unit;
wherein at least a portion of the camera module is inserted into the housing to move in a longitudinal direction of the housing and wherein a wiper is disposed within the housing to face the camera module;
wherein the controller configured to set a rotation angle of the housing based upon driving conditions of the vehicle, and to adjust extension of the camera module; and
wherein, when the housing is rotated, the camera module is configured to move synchronously with the housing horizontally in the longitudinal direction of the housing.
