Abstract
In a solid-state imaging element in which AD conversion using a reference signal is performed, power consumption of a circuit that generates the reference signal is reduced. A pixel section outputs a pixel signal based on the light amount of incident light. A reference signal supply section generates a first reference signal and a second reference signal. A comparison section includes a first differential pair transistor to which the pixel signal and a signal based on the first reference signal are inputted and a second differential pair transistor to which the second reference signal is inputted. A counter section performs counting on the basis of a signal from the comparison section.
