Abstract
An optical scanner includes a CCD and a light monitor window ('LMW') and a black region adjacent the LMW. The LMW is imaged to provide feedback signals for Red, Green and Blue channels of the CCD. The black region is imaged to remove flare from the feedback signals. The flare-corrected feedback signals may be supplied to gain compensation controls.
