Abstract
The present disclosure provides an imaging device and an electronic apparatus that can be made smaller in size, are capable of high-speed reading, and do not cause degradation of a captured image. The imaging device includes: a pixel that outputs a photoelectric conversion signal corresponding to an incident light quantity; and a comparator that compares the photoelectric conversion signal with a reference signal. The comparator includes: a differential circuit that outputs a signal corresponding to a signal difference between the photoelectric conversion signal and the reference signal; and a differential control circuit that sets an operating point of the differential circuit within a signal reset period before an operation of comparing the photoelectric conversion signal with the reference signal is started.
