ABSTRACT:
A scanner for obtaining an image of an object placed on an at least partially transparent platform, wherein the platform has at least a first scan area and a second scan area. The scanner includes a white area formed at least partially around the edge portions of the platform with a plurality of markers, one rotatable mirror, one or more image sensors. In scanning, each partial image from each of the scan areas includes an image of at least one portion of the plurality of markers. An image processing system uses the image of the at least one portion of the plurality of markers in each of the consecutive partial images as a reference to combine the consecutive partial images so as to form a substantially complete image of the object corresponding to a full scan of the first scan area and the second scan area.
