摘要： 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.

摘要： To control an excess bias to an appropriate value in a light detection device.
A solid-state image sensor includes a photodiode, a resistor, and a control circuit. In this solid-state image sensor, the photodiode photoelectrically converts incident light and outputs a photocurrent. Furthermore, in the solid-state image sensor, the resistor is connected to a cathode of the photodiode. Furthermore, in the solid-state image sensor, the control circuit supplies a lower potential to an anode of the photodiode as a potential of the cathode of when the photocurrent flows through the resistor is higher.
