Abstract:
1. An image capture device comprising: a solid-state image sensor; an optical system for producing an image on an imaging area of the solid-state image sensor; and a signal processing section for processing an electrical signal supplied from the solid-state image sensor, wherein the solid-state image sensor includes a photosensitive cell array, in which a number of photosensitive cells are arranged two-dimensionally on the imaging area, and a dispersive element array, in which a number of dispersive elements are arranged for some of the photosensitive cells that form the photosensitive cell array, and wherein the photosensitive cell array and the dispersive element array are formed of a number of units, and wherein each said unit includes first, second and third photosensitive cells, and at least one dispersive element, which is arranged so as to face at least one of the first and second photosensitive cells, and wherein in each said unit, each said dispersive element makes a part of its received light, which falls within a first wavelength range including at least a green wavelength range, incident on the photosensitive cell that faces the dispersive element, and also makes another part of its received light, which falls within a non-first wavelength range, incident on at least one photosensitive cell other than the photosensitive cell that faces the dispersive element, and wherein the first, second and third photosensitive cells respectively output first, second and third photoelectrically converted signals representing the intensities of the light received by them, and wherein the signal processing section outputs color information by making computations on the first, second and third photoelectrically converted signals.
