Abstract:
1. An image pickup device comprising: an image pickup unit including an n number of photodetectors and an n number of lenses (where n>=2), the lenses being provided in a one-to-one correspondence with the photodetectors, the lenses being provided so that light is incident upon only the respective photodetectors, the image pickup unit outputting signals corresponding to the respective photodetectors; a sensitivity coefficient storage section that stores information for determining sensitivity coefficients of the photodetectors; and an image reproducing section that reproduces an image using the signals that are output by the image pickup unit and the sensitivity coefficients that are determined on the basis of the information stored in the sensitivity coefficient storage section, wherein the image reproducing section includes: part for obtaining the signals that are output by the image pickup unit; part for setting a plurality of imaginary light spots in an image pickup area so that a number m of imaginary light spots≦the number n of photodetectors; part for determining the sensitivity coefficient corresponding to each imaginary light spot for each photodetector on the basis of the information stored in the sensitivity coefficient storage section; part for determining u where a light beam of an imaginary light spot i is u part for forming and outputting the image using the determined u
