<P>PROBLEM TO BE SOLVED: To prevent deterioration of image quality even when a subject is imaged in any of plural photographic systems. <P>SOLUTION: When a control part 5 picks up images of subjects in plural photographic systems with different pixel pitches in one direction of a pixel corresponding to a light receiving part used for imaging with an imaging element 15 via an angle variable part 23, using an optical element 12 having an optical anisotropy and capable of changing a width for isolating a photographic light L1 into two light rays in one direction according to an arrangement angle, the optical element 12 is arranged at the arrangement angle corresponding to the photographic system. Thereby, when an image of artificial regular patterns is picked up as a subject by plural photographic systems, even if a pixel pitch in one direction of the pixel and a Nyquist frequency in space-sampling a photography image with the imaging element 15 are different, a high frequency component of a space frequency of not less than the Nyquist frequency is removed from the photography image to reduce folding distortion, and thereby, deterioration of image quality can be prevented even if the image of the subject is picked up by any of plural photography systems. <P>COPYRIGHT: (C)2012,JPO&INPIT |
