Abstract
This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.

A graphical user interface for positioning a camera while capturing a series of images of portions of an object comprising:
- a viewing region displaying a composition of a previously acquired image and a current image.
The graphical user interface of claim 42 wherein the viewing region displays half of the previously acquired image as opaque and half of the previously acquired image as semi-transparent;
- and
- wherein the current image overlaps the portion of the previously acquired image that is semi-transparent and the portion of the current image that overlaps the previously acquired image is also semi-transparent, while the non-overlapping portion of the current image is displayed as opaque.
