An apparatus for changing the changeover pixels during an actual scan of an input medium including means for scanning across a two-dimensional surface during a non-actual scan, wherein the means for scanning includes at least two optically butt image sensors. The apparatus also includes means, operative during the non-actual scan, for determining the changing locations of changeover pixels of the image sensors, the changing locations caused at least by non-uniformities in the twodimensional surface and correction means, operative during the actual scan, for redefining the changeover pixels in accordance with the output of the means for determining. |
