Claim Text:
1. A solid state image sensor comprising: a light receiving unit where a plurality of photoelectric conversion elements storing charges according to a received light amount are arrayed in a lattice shape; a reading unit configured to read an imaging signal based on the charges stored by the light receiving unit; and a color filter including: red filters where each transmits light of a red wavelength band; green filters where each transmits light of a green wavelength band; and blue filters where each transmits light of a blue wavelength band, each of the red, green, and blue filters being disposed at a position corresponding to any one of the plurality of photoelectric conversion elements on a light receiving plane of the light receiving unit, wherein the color filter includes filter units where each includes the red, green, and blue filters arrayed in four rows and four columns, and the filter units are arrayed in a lattice shape, wherein the filter unit is set so that a total number of the green filters is six or more and eight or less, a total number of the blue filters is six or more and eight or less, a total number of the red filters is two or more and four or less, and a total number of the red, green, and blue filters is sixteen, the filter unit is partitioned into read units, each read unit includes two filters where each transmits light of the same wavelength band, and the two filters are adjacent to each other in one direction, and wherein the reading unit is configured to collectively read charges stored by two photoelectric conversion elements corresponding to the read unit.
