Patent ID: 7586530

Claim:
A solid-state imaging device comprising: pixels arranged in a two-dimensional array, each of said pixels including a light receiving element and an optical element formed closer to a light receiving side of each of said pixels than said light receiving element, said optical element of each of said pixels having a surface made of metal, an aperture, convex parts arranged cyclically, a cyclical pitch between each pair of adjacent convex parts, and a pattern of said convex parts, wherein the cyclical pitch and the pattern of said convex parts for said optical element of each of said pixels is different from the cyclical pitch and the pattern of said convex parts for said optical element of each other of said pixels, and the cyclical pitch between each pair of adjacent convex parts in said optical element and a width of each convex part in said optical element is greater than 0 and equal to or less than 1 wavelength of light to be condensed, and wherein a first pixel of said pixels is disposed in a peripheral part of the two-dimensional array and a second pixel of said pixels is disposed in a center part of the two-dimensional array, and the cyclical pitch of said optical element of said first pixel is greater than the cyclical pitch of said optical element of said second pixel.
