System and method for correcting erroneous image signals from defective photosensitive pixels during analog-to-digital conversion

摘要

A system and a method for correcting erroneous image signals from defective photosensitive pixels utilizes an analog-to-digital converter (ADC) architecture that corrects the erroneous image signals as image signals are being converted from analog signals to digital signals. The erroneous image signals are corrected by limiting the deviation of a given analog image signal from a previously processed image signal.
