Abstract: A system and method that compensates for noise in image information. The method comprises receiving test information for a plurality of pixels, determining a base compensating value based upon the test information, determining a plurality of differential compensating values, each differential compensating value based upon a difference between the test information for each of the corresponding pixels and the base compensating value, and storing the base compensating value and the plurality of differential compensating values.

Abstract: A scanner performs an initial calibration for lamp intensity before scanning, and a final calibration for lamp intensity after scanning. At least some compensation is performed after scanning is completed, using calibration values computed by interpolating between the initial calibration values and the final calibration values. As a result, the overall time is reduced substantially, because scanning can start without waiting for the lamp to stabilize. Linear interpolation may be used, or an additional calibration strip along the side of the image being scanned may provide calibration data for non-linear interpolation.
