ABSTRACT:
Systems, methods and apparatus are provided through which in some embodiments field-effect-transistor (FET) leakage is estimated recursively from a pixel value obtained when the FET is off. The corrected pixel value is then obtained by subtracting the FET leakage estimate from the pixel value read when the FET is on. A weighing factor is introduced for the FET leakage estimation to achieve the balance between image noise and correction resolution.
