Abstract
A reading part, in a first reset period PR, holds reset transistors in all pixels in a conductive state and executes a first conversion gain reset readout processing HCGRRD, stores an AD conversion code with respect to a first readout reset, signal HCGVRST in a memory part, then, in a transfer period PT, holds the transfer transistors in all pixels in a conductive state to transfer the accumulated charges in photodiodes PDto FDto thereby execute a global shutter operation accumulating overflowed charges in storage capacitors CS. The reading part, when reading each row, executes a first conversion gain signal readout processing, a second conversion gain signal readout processing, and a second conversion gain reset readout processing in order. Due to this, it becomes possible to realize digital pixels provided with a global shutter function at a small pixel pitch.
