Abstract:
A pixel driving portion 102 can carry out first read drive with which a transfer element is turned OFF in accordance with a drive signal TG to output a signal at an output node, and second read drive with which the transfer element is turned ON in accordance with the drive signal TG to transfer signal charges to the output node, thereby outputting a signal at the output node. A pixel signal reading portion 103, 104 outputs a signal corresponding to a difference between the signal read out in accordance with the second read drive and the signal read out in accordance with the first read drive.
