Method of scanning regions larger than the scan swath using a handheld scanner
First Claim
1. A method of swipe-scanning and printing onto a graphic image pre-printed on a surface, said method comprising the steps of:
- (i) operatively positioning a scanner relative to the surface and swiping the scanner across the surface, said scanner having a scanhead and a printhead;
(ii) capturing, during said swipe, successive images of portions of the graphic image using said scanhead;
(iii) printing, during said swipe, successive parts of a position-coding pattern onto the surface using said printhead, said position-coding pattern being superimposed with said graphic image;
(iv) imaging, during said swipe, portions of said surface on which said printhead has printed said parts of the position-coding pattern;
(v) determining absolute positions of the scanner using the imaged parts of the position-coding pattern;
(vi) sensing an orientation of the scanner relative to the position-coding pattern; and
(vii) using the orientation together with said absolute positions to assemble said captured portions of said graphic image into a scanned graphic image.
