Abstract
An imaging device according to one embodiment of the present disclosure includes one or more light receiving pixels that generate electric charges according to an amount of received light through photoelectric conversion; one or more analog-to-digital conversion circuits that are provided for each of the light receiving pixels and that convert an analog signal read from each of the one or more light receiving pixels into a digital signal; and a plurality of pixel units each including the one or more light receiving pixels and the one or more analog-to-digital conversion circuits. The plurality of pixel units is disposed to allow the one or more light receiving pixels to be adjacent to each other in two pixel units that are adjacent to each other in a first direction.
