<P>PROBLEM TO BE SOLVED: To provide a light source identification apparatus and a light source identification method which can discriminate between artificial light and natural light. <P>SOLUTION: The light source identification apparatus 1 is equipped with a plurality of light detecting parts 10 which measure the light intensity of a specific wavelength band, and a determination part 30 which compares measured values of a plurality of light detecting parts 10 and discriminates between the natural light and the artificial light. The plurality of light detecting parts 10 has at least a first light detecting part 11 which has the first wavelength restriction filter 21 to restrict the wavelength of the visible light to penetrate, and a second light detecting part 12 which has the second wavelength restriction filter 22 to permeate the visible light of longer wavelength than that of the first wavelength restriction filter 21, wherein the first wavelength restriction filter 21 is an optical filter which penetrates the visible light of the wavelength band of 480-520 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
