WIPO Patent Application WO/2007/111317
Kind Code:
A1
Abstract:
Provided is a night vision device capable of increasing a spread of a field of view during night or in a bad weather and obtaining a highly sensitive image around the device and far from the device. The night view device includes: a headlight (2) formed by one or more than one light sources (2A to 2C) having a plurality of peaks in a wavelength spectrum of visible light region and emitting light from the visible light region to the infrared light region; an imaging camera (3) for receiving the light emitted from the headlight (2); and an optical band illumination filter (30) for cutting off only some peaks among the plurality of peaks. An image captured by the imaging camera (3) passes through the optical band illumination filter (30) and an output image is obtained.
