Claim One:
1. A method of processing signals from a first and a second image sensor that provide respective image signals recorded at respective areas of a scanned medium, where a portion of the respective areas is recorded also by the other of the respective image sensors, whereby image data from overlapping and non-overlapping areas are present in the respective signals; the method comprising: determining a first and a second level of intensity from image signals, at the overlapping area, from the first and the second image sensor respectively, determining a compensation value by processing the first level of intensity and the second level of intensity to determine a discrepancy between the first and second levels of intensity at the overlapping area; applying the compensation value, determined from the discrepancy between the first and second levels of intensity of image signals at the overlapping area, to image data from overlapping and non-overlapping areas to provide compensated image data to compensate for a discrepancy between levels of intensity from the first and the second image sensor, wherein the above steps are performed at the same time as a document is being scanned.
