Abstract
Provided is an imaging device that includes a pixel array section including a plurality of dynamic vision sensor (DVS) pixels that outputs a luminance signal according to a light amount, and a detection circuit section that is disposed outside the pixel array section and outputs a detection signal indicating occurrence of an address event in a case where the luminance signal of each of the plurality of DVS pixels exceeds a predetermined threshold value. Furthermore, each of DVS pixel includes a photoelectric conversion element that outputs a signal corresponding to a light amount, a logarithmic conversion circuit that logarithmically converts the signal, a signal holding circuit that holds the luminance signal converted by the logarithmic conversion circuit, and a readout circuit that reads the luminance signal held in the signal holding circuit.
