Abstract
In a solid-state imaging element that performs AD conversion for each pixel, image quality degradation when resolution is lowered is suppressed without wastefully consuming power. The solid-state imaging element includes a plurality of pixels. Each of the plurality of pixels is provided with a comparison unit, an addition circuit, and a data storage unit. The comparison unit generates a difference signal obtained by amplifying a difference between an analog pixel signal to which a predetermined coordinate is assigned and a predetermined reference signal. The addition circuit generates an addition signal by performing analog addition of the difference signal and a difference signal regarding another coordinate adjacent to the predetermined coordinate. The data storage unit holds a digital signal indicating a time when an output signal of the comparison unit corresponding to the addition signal is inverted.
