<P>PROBLEM TO BE SOLVED: To conduct near-infrared light irradiation without imposing load on a person's eyes. <P>SOLUTION: The irradiation direction, irradiation timing and irradiation intensity of near-infrared light with a light projector 2 are controlled, based on imaging timing and exposure time which an imaging device 21 provides; the presence or absence of a pedestrian, advancing direction of the pedestrian, the distance to the pedestrian, and direction which the pedestrian is facing which are all provided by an image-processing device 22; the vehicle speed which a vehicle-speed sensor 41 has measured; position information which a navigation device 42 provides; the intensity of illumination which an illumination-intensity sensor 44 has measured; a result of detection made by a raindrop sensor 44; operating conditions of a wiper 45 and fog lamp 46; and weather information which a VICS(R) receiving device 47 provides. <P>COPYRIGHT: (C)2007,JPO&INPIT |
