Abstract
A night visional apparatus is provided that can assist in enlarging the field of view at night or in bad weather, and can obtain image with high sensitivity over a range from a vicinity of the apparatus to a distant area. The night vision apparatus includes a headlamp having one or two or more light sources, to emit light ranging from a visible light region to an infrared light region, a plurality of peaks exiting in a wavelength spectrum in the visible light region; an imaging camera that received light emitted from the illuminating device; and an optical band elimination filter that blocks only a part of peaks among the plurality of peaks. An output image is obtained based on an image captured by the imaging camera through the optical band elimination filter.
