Abstract
The present disclosure provides an imaging device capable of outputting a signal other than an event detection signal, such as a pixel signal at a gradation level. The imaging device has a stacked chip structure formed by stacking at least two semiconductor chips including a first-layer semiconductor chip and a second-layer semiconductor chip. The first-layer semiconductor chip has a pixel array unit in which an event pixel that outputs an event detection signal, and a distance measurement pixel are mixed. The second-layer semiconductor chip is provided with an analog front-end unit for an event pixel that processes the event detection signal and with an analog front-end unit for a distance measurement pixel that processes the signal from the light-receiving element, corresponding to each of the event pixel and the distance measurement pixel.
