摘要：
An imaging device including a semiconductor substrate; a first photoelectric converter that is located in the semiconductor substrate and that generates a first signal charge by photoelectric conversion; a first node to which the first signal charge is input; a capacitor having a first terminal coupled to the first node; and a second photoelectric converter that is located in the semiconductor substrate and that generates a second signal charge by photoelectric conversion. The area of the second photoelectric converter is greater than the area of the first photoelectric converter in a plan view, and the number of saturation charges of a first imaging cell including the first photoelectric converter and the capacitor is greater than the number of saturation charges of a second imaging cell including the second photoelectric converter.
