Abstract
The solid state image sensor of this invention includes multiple units, each of which includes first and second photosensitive cellsand a dispersive elementfacing the first cell. The elementpasses a part of incoming light with a first color component to the second cell. The first cellreceives a smaller quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The second cellreceives a greater quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The quantity of that part of the incoming light with the first color component is calculated based on the difference between photoelectrically converted signals supplied from the first and second cellsandand information representing the ratio of the quantity of the light with the first color component received by the second cell to that of the part of the incoming light with the first color component.
