HANDHELD DEVICE DOCUMENT IMAGING
First Claim
1. A method of stitching a plurality of frames of a video sequence to image a target document, comprising:
- capturing a group of a plurality of frames of a video sequence using an image sensor of a handheld device having a display;
during said capturing, analyzing said video sequence to select iteratively a group of said plurality of frames, each member of said group depicts another of a plurality of segments of a target document;
during said capturing, sequentially presenting a plurality maneuvering indications, each said maneuvering indication is presented after a certain frame depicting a certain of said plurality of segments is captured and indicative of a maneuvering gesture required for bringing said image sensor to capture another frame depicting another segment of said plurality of segments, said another segment being complementary and adjacent to said certain segment; and
stitching members of said group to create a mosaic image depicting said target document as a whole.
