Abstract
[Problem] To reduce the number of signals transmitted and received between a plurality of stacked substrates and a plurality of layers. [Solution] An imaging device includes: a plurality of pixels each having a photoelectric converter; an analog-to-digital converter provided for each area pixel composed of two or more of the pixels in the plurality of pixels to convert a signal corresponding to a charge photoelectrically converted by the two or more pixels into a digital signal; a floating diffusion that outputs the charge photoelectrically converted by the photoelectric converter in the pixel; a plurality of stacked areas in which the plurality of photoelectric converters, the plurality of the analog-to-digital converters, and the plurality of the floating diffusions in the plurality of pixels are arranged; and a signal transmitter that transmits and receives signals between the plurality of areas. An area in which the plurality of photoelectric converters in the area pixel are arranged and an area in which the analog-to-digital converter is arranged transmit and receive a charge of the plurality of floating diffusions via the same signal transmitter.
