Abstract
The arrangement of a converging light device array wherein each converging light device increasing a quantity of incident light entering every one or more photoelectric conversion pixel is arranged in front of a photoelectric conversion surface of a solid state imaging device photoelectrically converting an optical image based on an objective optical system substantially ensures that an aperture area of the photoelectric conversion pixel enlarges and the sensitivity improves.
