Night vision imaging apparatus, infrared irradiation apparatus, and night vision imaging system

摘要

An imaging device (31) includes pixels (32, 33, 34) configured to sequentially output image signals for an infrared radiation (14a) having a first wavelength, an infrared radiation (14b) having a second wavelength and an infrared radiation (14c) having a third wavelength. A first pixel (32) has the sensitivity to a first color of a primary color and outputting a first signal in response to reception of the infrared radiation (14a) having the shortest wavelength of the first wavelength, the second wavelength and the third wavelength. A second pixel (34) has the sensitivity to a second color of the primary color and outputting a second signal in response to the reception of the infrared radiation (14a) having the shortest wavelength. A discriminating circuit (39) is configured to compare the first signal and the second signal with each other to discriminate a reception timing of an infrared radiation (14a) having a selected wavelength in response to a relative sensitivity ratio.
