Disclosed is a method of processing image signals from a first and a second image sensor, both of a document scanner unit, where the first image sensor provides a first image, and the second image sensor provides a second image. The first and the second image are two-dimensional images wherein said first and second image are 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. Thereby image data from overlapping and non-overlapping areas are present in the first and the second image. The method comprises: correlating the first image with the second image, creating a correlation image and processing the correlation image to determine a displacement between the first and the second image. Consequently, a versatile calibration method is provided that can determine a displacement between the first and the second image in two dimensions.
