Abstract
Column signal processing units are provided in correspondence with respective columns of a pixel array. The column signal processing unit includes a sample-and-hold unit configured to hold an analog signal output from a pixel, a buffer unit configured to buffer the signal held in the sample-and-hold unit, and an AD conversion unit. The AD conversion unit converts the signal held by the sample-and-hold unit and buffered by the buffer unit into a digital signal.
