Abstract
An image sensor includes: a photodiode configured to be reset for each one frame period, to accumulate charges corresponding to incident light for one frame period, and to output an output voltage corresponding to the accumulated charges; and a holding capacitor configured to accumulate charges corresponding to an output signal of the photodiode. The output signal of the photodiode for one frame is integrated, the integrated output signal is accumulated in the holding capacitor, and a first signal is output. After the holding capacitor is refreshed, a voltage corresponding to the output voltage of the photodiode is held in the holding capacitor, and a second signal is output.
