Abstract
An imaging device includes a pixel that outputs a signal based on charges generated by photoelectric conversion, a comparator that compares a pixel signal output from the pixel with a reference signal and outputs a signal in accordance with a comparison result, a buffer circuit that buffers a signal output from the comparator, a switch provided at least one of a part between the buffer circuit and a first node supplied with a first power source voltage and a part between the buffer circuit and a second node supplied with a second power source voltage, and a control circuit that controls the switch to a non-conductive state in a period in which the comparator performs a comparison operation to compare the pixel signal with the reference signal.
