Title: Operation method of photosensitive device
Inventor: HOSIER PAUL A
IPC: H04N5/378
Filed: 2002-03-15
Abstract: PROBLEM TO BE SOLVED: To conquer noise by sampling the actual value of charges on a photodiode during operation of a device and correcting subsequent video signals using that sample value. SOLUTION: In a photosensitive device having a photodiode 10, a 'fat zero' bias for preventing the nonlinear part of a response of the photodiode from being used is injected into a photodiode. For each cycle of operation, first fat zero charges are placed in the photodiode before sampling is performed. Subsequently, second fat zero charges are placed in the photodiode immediately before an optical signal from an image under recording is stored. The optical signal + second fat zero are transferred from the photodiode and the sample signal is subtracted therefrom to leave only the optical signal. This system removes both fixed pattern noise and a significant quantity of thermal noise in the photosensitive device.
