Abstract
A solid-state imaging device is capable of suppressing as much as possible an increase in power consumption of a low-frequency noise removing process. A pixel unit includes pixels outputting pixel signals corresponding to an amount of incident light and correction pixels outputting correction pixel signals corresponding to a correction reference voltage. An AD conversion circuit includes a delay circuit, to which a plurality of delay elements are connected, and outputs a digital signal corresponding to the number of delay elements through which a pulse signal passes when the pulse signal passes through the number of delay elements corresponding to a level of the pixel signal or the correction pixel signal.
