SOLID-STATE IMAGING DEVICE AND SIGNAL PROCESSING SYSTEM

摘要

A solid-state imaging device includes: a pixel portion configured to convert light into an electric signal; a substrate where the pixel portion is formed; an A/D conversion unit configured to convert a signal read out from the pixel portion into a digital signal; and an optical communication unit configured to convert a signal digitized by the A/D conversion unit into an optical signal, and output the optical signal, with the single optical communication unit or a plurality of the optical communication units being disposed grouped in the vicinity portion of the substrate around the pixel portion.
