A method of compensating for image intensity variation in a scanline of a scanned image caused by variation in sensor integration time in a non-shuttered CCD image sensor comprising the steps of (a) determining for the scanline a multiplicative compensation factor, Kc (b) multiplying the sensed intensity of light received by sensor elements present in the CCD image sensor for the scanline by Kc to produce a compensated intensity value for the scanline and (c) employing the compensated intensity value in an image processing pipeline to produce the scanned image.
