Abstract
Provided is an imaging device with low noise and a high dynamic range. An imaging device includes: a conversion unit that converts an incident electromagnetic wave into a charge; a first capacitor that accumulates the charge when a voltage corresponding to the charge is equal to or lower than a predetermined threshold; a second capacitor that accumulates the charge when the voltage exceeds the threshold; a voltage conversion circuit that converts the charges accumulated in the first capacitor and the second capacitor into voltages; a first storage unit that stores a voltage corresponding to the accumulated charge in the first capacitor after a lapse of a first period since the first capacitor has started accumulating the charge; and a second storage unit that stores a voltage corresponding to the accumulated charges in the first capacitor and the second capacitor after a lapse of a second period longer than the first period since the first capacitor has started accumulating the charge.
