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). According to this construction, the plurality of pixels have different sensitivities to incident light. By combining pixel signals obtained from three pixels having different sensitivities, a wider dynamic range can be achieved.
