Patent ID: 7851837

Claim:
A solid-state imaging apparatus comprising pixels that are arranged in a two-dimensional array, each of said pixels including a light-collector and a light-receiver, wherein said light-collector includes: a substrate onto which incident light is incident; above said substrate, a plurality of light-transmitting films formed in a region onto which the incident light is incident; and said plurality of light-transmitting films forming a plurality of zones each of which has a width equal to or shorter than a wavelength of the incident light, and forming an effective refractive index distribution, wherein, for each of said pixels located in a center of an imaging area, a central axis of said light-receiver matches a central axis of said light collector, the imaging area being a plane on which said pixels are formed, wherein, for each of said pixels located in a periphery of the imaging area, the central axis of said light-collector is displaced from the central axis of said light-receiver toward the center of the imaging area, wherein each of said plurality of light-transmitting films included in one of said pixels located in the center of the imaging area corresponds to a relative one of said plurality of light-transmitting films which is in a same relative position in one of said pixels located in the periphery of the imaging area, wherein each of said plurality of light-transmitting films included in the one of said pixels located in the center of the imaging area has a line width different than a line width of the corresponding relative one of said plurality of light-transmitting films included in the one of said pixels located in the periphery of the imaging area, and wherein a sum of the line widths of said light-transmitting films included in the one of said pixels located in the center of the imaging area differs from a sum of the line widths of said light-transmitting films included in the one of said pixels located in the periphery of the imaging area.
