Abstract:
1. A night vision apparatus for taking an image of a subject by using reflected light of infrared light emitted, the night vision apparatus comprising: an image segmenting unit configured to segment said image into a plurality of regions based on a luminance value of a lighting image taken when the infrared light is emitted and a luminance value of a non-lighting image taken when the infrared light is not emitted; and a luminance value correcting unit configured to correct luminance values of the regions based on characteristics of the regions segmented by the image segmenting unit, wherein the image segmenting unit is further configured to segment a first region in said image whose luminance value of the non-lighting image is smaller than a first threshold, and whose luminance value of the lighting image is larger than a second threshold as a high-reflection region, and the luminance value correcting unit is further configured to correct the luminance values of the first region based on the luminance values of the corresponding region of the non-lighting image.
