<P>PROBLEM TO BE SOLVED: To provide a technology for screening light with a luminescent color deleterious to a normal operation by a driver without screening light in a required range of wavelengths by an inexpensive constitution. <P>SOLUTION: A projector 3 in an image pickup device 100 keeps a plurality of LEDs on a circuit board 3d regularly in an array shape. In concrete, a red reduction LED 3b and near-infrared LED 3a of the arranged LEDs are disposed on the circuit board 3d. The projector 3 is mounted in proximity to a dashboard in an instrument panel as well as a camera 2, arranged close to the camera 2, and is controlled by a control circuit not illustrated so as to be turned on in conjunction with a shutter of the camera 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
