Abstract:
1. An imaging device comprising: a plurality of lens units each including at least one lens; a plurality of imaging areas corresponding one-to-one with the plurality of lens units, and each having a light receiving surface substantially perpendicular to an optical axis direction of the corresponding lens unit; an imaging signal input unit that receives as input a plurality of imaging signals each output from a different one of the plurality of imaging areas; an intensity correction coefficient saving unit that saves an intensity correction coefficient, which is information concerning intensity unevenness in the imaging areas that corresponds to a bias of light intensity distribution depending on a position within each of the imaging areas; an intensity correcting unit that corrects an intensity of each of the plurality of imaging signals using the intensity correction coefficient such that the degree of correction changes depending on the position in the imaging area, so as to reduce an effect of intensity unevenness in the imaging areas that corresponds to the bias of light distribution depending on the position within each of the imaging areas; and a parallax calculating unit that derives a parallax, representing shift amounts in relative positions of images of the same object formed respectively on the plurality of the imaging areas by the plurality of lens units, based on the imaging signals whose intensity has been corrected by the intensity correcting unit.
