ABSTRACT:
An image pickup device includes an image pickup unit including an n number of photodetectors and an n number of lenses, and outputting signals corresponding to the respective photodetectors, the lenses being provided in a one-to-one correspondence with the photodetectors and being provided so that light is incident upon only 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. In a model in which light from imaginary light spots is received by the respective photodetectors, using the output signals and the sensitivity coefficients corresponding to the respective photodetectors, the image reproducing section estimates light beams of the respective imaginary light spots, and using brightness values corresponding thereto as brightness values of respective pixels of an image corresponding to an image pickup area, the image reproducing section reproduces an image.
