Abstract:
A power supply voltage containing a noise component is supplied to each pixel at the time of sampling of a reset level of a signal read out from each pixel, and a power supply voltage in which the noise component is suppressed is supplied to each pixel at the time of sampling of a read level of the signal read out from each pixel.
