Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for driving a solid-state image pickup element having (a) a plurality of pixel circuits, each including (i) an output node, (ii) a photoelectric conversion element configured to convert an optical signal into an electrical signal and accumulate the electrical signal, and (iii) a transfer element configured to be turned ON and OFF in accordance with a drive signal and transfer the electrical signal in the photoelectric conversion element in an O…
