<P>PROBLEM TO BE SOLVED: To provide a vehicular night-vision device capable of preventing halation of a camera due to irradiation of infrared light from an oncoming vehicle without precise controlling. <P>SOLUTION: By controlling of the controller 9, either one of a plurality of infrared band-pass filters 50A to 50C respectively passing wavelength bands that do not overlap each other arranged on a disc 50 of a selecting-type filter 5 is positioned on an optical axis of a lamp light source 4. Therefore, the wavelength band of the infrared light irradiated from an irradiating portion 2 is selected. The wavelength band of reflected light shot by an infrared camera 7 of a shooting portion 3 is also selected by a selecting-type filter 6 in the same way. The controller 9 controls the selecting filters 5, 6 to make the wavelength bands which are selected by the selecting-type filters 5, 6 same. Furthermore, when the infrared light having the same wavelength band is irradiated from a night-vision device 1A of the oncoming vehicle, the controller 9 controls to select the wavelength band that is different from the night-view device 1A of the oncoming vehicle. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
