Abstract
A pixel of an image sensor includes a photodiode, a reset transistor, a peak hold transistor, and a first capacitor and a second capacitor. The pixels include, a first mode in which the noise and image output voltages of the photodiode are held in the first and second capacitors, respectively, and a second mode in which the output voltage of the photodiode in a state where the reset transistor is turned on to reset the photodiode is held in the first capacitor or the second capacitor. In the first mode, an image signal corresponding to the light incident amount of the photodiode and a noise signal when the light incident amount is relatively low are obtained. In the second mode, a noise signal when the light incident amount of the photodiode is relatively high is obtained.
