Abstract
An imaging device includes a photoelectric conversion element which photoelectrically converts incident light and generates a charge, accumulates and amplifies the charge, and outputs a photocurrent, wherein a level of an output signal when a charge which is accumulated in the photoelectric conversion element is outputted over a saturated amount of accumulable charge includes a level of an output signal of a charge of a photocurrent of DC component which is generated in the photoelectric conversion element and outputted during a readout time when the charge which is accumulated in the photoelectric conversion element is outputted.
