Title: Charge multiplying solid-state electronic image sensing device, and method of controlling the same
Inventor: HAKAMATA KAZUO
IPC: H04N5/374
Filed: 2002-08-14
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuations of the multiplication factor in a charge multiplying CCD. SOLUTION: Signal charges accumulated in photodiodes 2A of a photoreceptor area 2 in a CCD 1 are multiplied by a charge multiplier 8 and then applied to a floating diffusion amplifier FDA 11, which has been set to a small conversion coefficient, or to floating gate amplifier FGA 12, which has been set to a large conversion coefficient. If the accumulated amount of signal charges is small, the charges are converted to a video signal by the FGA 12 having the large conversion coefficient. If the accumulated amount of signal charges is large, the charges are converted to a video signal by the FDA 11 having the small conversion coefficient. Thus, a video signal having a high level is obtained even if the amount of signal charges is small.  Since it is unnecessary to change driving pulses that are applied to the charge multiplier 8, the multiplication factor of the charge multiplier 8 does not fluctuate.
