PhotoVoltaic Image Sensor

Abstract

An image sensor is an image sensor including a plurality of pixels. Each of the pixels includes a photodiode configured to generate charges based on a light incident amount, a reset transistor configured to reset the photodiode by supplying a reset voltage to the photodiode, a first capacitor configured to hold an output voltage of the photodiode immediately after the reset, and a second capacitor configured to hold the output voltage of the photodiode after a predetermined exposure period. An image signal is obtained from the voltage held by the first capacitor and the voltage held by the second capacitor.
