Abstract
A solid-state imaging device according to the present invention includes a pixel cell having a photodiode, a charge detection unit, an amplification transistor, a transfer transistor which transfers a signal charge to the charge detection unit in accordance with a transfer control signal, and a reset transistor which resets the charge detection unit in accordance with a reset control signal; a signal processing circuit which receives a pixel reset potential of the charge detection unit, and a pixel signal potential corresponding to the signal charge transferred to the charge detection unit; a charge pump circuit which steps up or steps down a potential of at least one of the transfer control signal and the reset control signal in accordance with a driving clock signal; and a control logic circuit which causes the driving clock signal to be stopped during a pixel reading time period.
