Abstract
A method of correcting lag in an imaging pixel includes receiving a current frame pixel value and determining a current filter coefficient using the current frame pixel value. A pixel output is determined from a product of the current frame pixel value and current frame filter coefficient. The product of a first prior frame pixel value and corresponding first prior frame filter coefficient is added to the pixel output to generate a corrected pixel output to more closely indicates incident illumination on the imaging pixel during an integration period from which the current frame pixel value was obtained.
