摘要:
A solid-state imaging device includes: a pixel section formed on a substrate and having an effective pixel area that converts incident light into an electric signal, and an optical black area placed around the effective pixel area; an optical communication section placed near a predetermined optical black area of the optical black area, and converts a signal read from the pixel section into an optical signal for output; a dark current level supplying section that generates an estimated dark current level varying with a pixel position from which a signal is read, on the basis of a dark current level acquired from the predetermined optical black area, and outputs the estimated dark current level in synchronization with a signal read timing from the effective pixel area; and a noise compensation section that subtracts the estimated dark current level from a signal read from the effective pixel area.
