Abstract
According to an aspect of the present invention, there is provided an imaging device including: a plurality of pixels, each pixel including a photoelectric conversion unit that photoelectrically converts received light, a read node in which a signal charge generated in the photoelectric conversion unit is accumulated, and a first readout circuit that performs analog-to-digital conversion to convert a signal based on the signal charge accumulated in the read node into a digital signal; and a second readout circuit that reads a signal based on the signal charge, the signal having a smaller amplitude than a resolution of the analog-to-digital conversion of the first readout circuit.
