Abstract: A high efficiency multi-image scanning method is disclosed. It involves the use of a special scanning window, or panel, containing a plurality of rectangular fields provided therein. The scanning window also contains a plurality of fiducial marks which associates each rectangular field, respectively, with a pre-defined location relative to the fiducial mark and a pre-defined scanning area. Prior to the scanning operation, a plurality of documents to be scanned are placed inside the rectangular fields. A pre-scan operation is performed to find and identify the fiducial mark. Then the scanner is moved to a selected rectangular field according to the information contained in the fiducial mark to scan an image having the pre-defined scanning area. Optionally, the method further contains the step of determining whether an image is present in the rectangular field, and if so, then adjusting the scanning area to compensate for any inadvertent misplacement of the image in the rectangular field.
