Abstract
According to one embodiment, a solid-state imaging device including a plurality of pixels two-dimensionally arranged at a preset pitch in a semiconductor substrate is provided. Each of the pixels is configured to include first and second photodiodes that photoelectrically convert incident light and store signal charges obtained by conversion, a first micro-lens that focuses light on the first photodiode, and a second micro-lens that focuses light on the second photodiode. The saturation charge amount of the second photodiode is larger than that of the first photodiode. Further, the aperture of the second micro-lens is smaller than that of the first micro-lens.
