To provide a photographic device which can be realized by an optical configuration using generally widely used imaging devices and allows the number of bands necessary for spectrometry of a subject to be picked up by one-time imaging.
The photographic device has; a plurality of imaging devices 103, 104, and 105 of the same kind, each of which has three kinds of RGB light receiving cells for outputting color signals corresponding to the intensity of received light; and a color separation optical system 102 which has dichroic mirrors 204 and 205 for separating composite light L from a subject, which includes wavelengths of RGB bands which the imaging devices are sensitive to, into a plurality of light beams by wavelengths per sensitivity band of RGB light receiving cells and separates each separated light beam into first to third optical paths 231 to 233 and causes respective light beams to impinge on corresponding imaging devices. Each imaging device outputs spectral information based on light of wavelengths different by sensitivity bands on the basis of incident light including light of different wavelengths, which is divided into a plurality of light beams per sensitivity band of RGB.
