摘要： A solid-state imaging device includes a plurality of pixels arranged two-dimensionally. Each pixel includes a photoelectric converter (2) for converting incident light to a charge, and a gray filter (6a, 6b, 6c) having a visible light transmittance that is different depending on the photoelectric converter (2).
