Abstract
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.
