Abstract
A solid-state imaging device that is configurable into a small size appropriate for expanding dynamic range includes: a photodiode which is a photoelectric conversion unit that generates charge by incident light; a MOS transistor which is connected to the photodiode and transfers the charge; a floating diffusion region which is a first accumulation unit which accumulates the charge via the MOS transistor; a MOS transistor which is a second transfer unit connected to the floating diffusion region and connected in series to the MOS transistor; and a MOS transistor which is an output unit which outputs, via the MOS transistor, a signal voltage in accordance with an amount of the charge.
