Abstract

A solid-state imaging device includes a pixel signal-processing unit which includes a plurality of pixels arranged in a two-dimensional matrix, wherein the pixel signal-processing unit outputs an total pixel signal while outputting a reduced pixel signal; a difference calculation unit which outputs a digital value obtained by calculating a difference between a digital value indicating a magnitude of the total pixel signal and a digital value indicating a magnitude of the reduced pixel signal; and a bit number reduction unit which reduces the number of bits of either the digital value obtained by calculating the difference, or the digital value indicating the magnitude of the total pixel signal, and outputs a digital value whose number of bits is reduced, wherein the solid-state imaging device outputs the digital value corresponding to the total pixel signal and the digital value indicating the magnitude of the reduced pixel signal.
