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 of visual maneuvering indications on said display, while said display presents said plurality of frames, each said visual maneuvering indication is presented after a frame depicting a segment of said plurality of segments of said target document is captured and said visual maneuvering indication is 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 previous segment; and
,stitching members of said group to create a mosaic image depicting said target document as a whole.

Abstract
A method of stitching frames of a video sequence to image a target document. The method comprises capturing a group of frames of a video sequence using an image sensor of a handheld device having a display, during the capturing, analyzing the video sequence to select iteratively a group of the frames, each member of the group depicts another of segments of a target document, during the capturing, sequentially presenting a plurality maneuvering indications, each the maneuvering indication is presented after a certain frame depicting a certain of the segments is captured and indicative of a maneuvering gesture required for bringing the image sensor to capture another frame depicting another segment of the segments, the another segment being complementary and adjacent to the certain segment, and stitching members of the group to create a mosaic image depicting the target document as a whole.

16. A handheld device of stitching a plurality of frames of a video sequence to image a document, comprising:
-
an image sensor which captures a group of a plurality of frames of a video sequence; a display; a processor; an analysis module which uses said processor to analyze 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 document; a maneuvering indication module which sequentially presents a plurality of visual maneuvering indications on said display, while said display presents said plurality of frames, during said capturing, each said visual maneuvering indication being presented on said display after a frame depicting a segment of said plurality of segments of said document 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 previous segment; and a stitching module which stitches said plurality of segments to create a mosaic image depicting said document as a whole. - View Dependent Claims (17)

18. A non-transitory computer readable storage medium encoded with computer executable instructions for performing steps including stitching a plurality of frames of a video sequence to image a document, said steps comprising:
-
capturing a group of a plurality of frames of a video sequence using an image sensor of a handheld device having a display; analyzing, during said capturing, 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 document; presenting sequentially, during said capturing, a plurality of visual maneuvering indications, on said display, while said display presents said plurality of frames, each said visual maneuvering indications 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 said plurality of segments to create a mosaic image depicting said document as a whole.
