Abstract
A method for dynamically compensating for a faulty pixel in a scan line of a scanner having an image sensor with a plurality of sensor pixels includes generating digitized scan data; processing the digitized scan data to compensate for any faulty pixels of the plurality of sensor pixels to form compensated scan data; processing the compensated scan data to apply offset and gain correction to the compensated scan data to form calibrated scan data; processing the calibrated scan data to adjust the calibrated scan data to compensate for human visual perception to form final scan data; and storing the final scan data in a scanner image memory.
