Patent ID: 7863633

Claim:
A solid-state imaging device comprising: photodiodes which are two-dimensionally arranged; light condensers each of which condenses light and is positioned to correspond to two of said photodiodes which are adjacent to each other; and light separators each of which is operable to separate the light entering through said light condensers into first light having a wavelength within a predetermined range, and second light having a wavelength out of the predetermined range, each light separator positioned to correspond to one of said light condensers, wherein each of said light separators includes: a light selector operable to selectively allow transmission of one of the first light and the second light and reflect the other one of the first light and the second light, and to allow the transmitted light to enter one of the corresponding two of said photodiodes; and a light reflector operable to reflect the light, reflected by said light selector, towards the other one of the corresponding two of said photodiodes, wherein said light separators include first type light separators and second type light separators, wherein the first light separated by said first type light separators is first primary color light indicating a first primary color, among red, green and blue, and the second light separated by said first type light separators is a first complementary color light indicating a color which is complementary to the first primary color, and wherein the first light separated by said second type light separators is second primary color light indicating a second primary color which is different from the first primary color, and the second light separated by said second type light separators is a second complementary color light indicating a color which is complementary to the second primary color.
