Handheld scanner for coded surfaces
First Claim
1. A swipe scanner for scanning a graphic image printed on a surface, said surface having a position-coding pattern imposed with the graphic image, said swipe scanner comprising:
- at least one first image sensor positioned for imaging portions of said surface during a swipe of the surface, each imaged portion containing part of the position-coding pattern;
at least one second image sensor for capturing, during said swipe, portions of the graphic image; and
a processor configured for;
determining absolute positions of the swipe scanner using said parts of the position-coding pattern; and
using the absolute positions to assemble said captured portions of said graphic image into a scanned graphic image,wherein each imaged part of position-coding pattern encodes orientation data identifying an orientation of the position-coding pattern, and wherein said processor is configured to use each imaged part of the position-coding pattern to determine the orientation of the scanner relative to the position-coding pattern, and to use said orientation together with said absolute positions to assemble said captured portions irrespective of swiping said scanner in a plurality of different directions during scanning.

Abstract
A swipe scanner for scanning a graphic image printed on a surface. The surface has a position-coding pattern imposed with the graphic image. The swipe scanner comprises: (a) a first image sensor positioned for imaging portions of the surface during a swipe of the surface, each imaged portion containing part of the position-coding pattern; (b) a second image sensor for capturing, during the swipe, portions of the graphic image; and (c) a processor. The processor is configured for: determining absolute positions of the swipe scanner using the parts of the position-coding pattern; and (d) using the absolute positions to assemble the captured portions of the graphic image into a scanned graphic image.
