Imaging device and electronic apparatus

An electronic apparatus comprising:

• an imaging device that outputs a photoelectrically converted digital signal for each pixel;
• and
• a signal processor that performs signal processing on the digital signal, wherein the 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 pixels, the plurality of the analog-to-digital converters, and the plurality of the floating diffusions are arranged;
• and
• a signal transmitter that transmits and receives signals between the plurality of areas, wherein
• among the plurality of areas, an area in which the plurality of photoelectric converters are arranged is provided separately from an area in which the analog-to-digital converter is arranged, and
• the signal transmitter transmits and receives a charge of the floating diffusion between the area in which the photoelectric converter is arranged and the area in which the analog-to-digital converter is arranged.
