Abstract:
A solid-state imaging device including: pixel section having two-dimensionally arranged pixels, each pixel containing photoelectric conversion device, charge retaining section, amplification section, and reset section controlled by reset control signal applied on control terminal, pixel section having vertical signal line and constant current supply; CDS circuit for outputting pixel signal corresponding to light signal by computing difference between first signal outputted from the pixel immediately after applying first potential to control terminal and second signal outputted from pixel corresponding to signal charges; and reset section control section taking potential of reset control signal at the time of cutting off connection between the one end and the other end of reset section as second potential, for applying third potential being intermediate potential between first potential and second potential to control terminal between a timing of outputting the first signal and a timing of outputting the second signal.
