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.

Abstract: An interactive desktop system for automatically adjusting pan and zoom functions to change a field of view in response to user actions relative to a feedback image projected on a source document. The interactive desktop system includes an image capture system, a display system and a processor system. The image capture system grabs an image from the source document in its field of view. The display system indicates to a user the captured image using the feedback image, which is visible to the image capture system. In response to a user adjustment of the feedback image, the processor system adjusts either the pan or zoom function of the image capture system, thus changing the field of view of the image capture system.

Abstract: A scanner for scanning an image on a large-format medium and generating image information. The scanner includes a secondary substrate mounted to the frame and having a length spanning the width of the medium, and a plurality of sensor boards disposed on the secondary substrate. A plurality of sensor dies are mounted on each of the sensor boards. The scanner further includes a lens strip, mounted to the frame between the sensor dies and the moving means. Preferably, a die on each end of each sensor board overhangs the end of the board, and the sensor boards are mounted on the secondary substrate so that dies overhanging ends of the sensor boards are butted against each other. The sensor dies may be wired in groups, so that image information read from the sensors in a group passes through the same data path; image information is read from a first set of sensor dies, wherein only one sensor die from each group is in the first set; and immediately after reading image information from the first set of sensor dies, image information is read from a second set of sensor dies, wherein only one sensor die from each group is in the second set, and wherein each of a plurality of sensor dies in the second set is separated by at least one other sensor die from the sensor die in the first set that is in the same group.

Abstract: In a multi-plane electronic whiteboard apparatus, a drawing sheet is extended on a main roller and driven rollers so as to be folded back once by means of the intermediate driven roller. The main roller has a diameter larger than (at least not less than twice) the diameter of the driven rollers to ensure a space for forming the folded portion. A portion of the drawing sheet is exposed through an opening of a frame for serving as a drawing plane. The folded portion contributes to providing a total of four drawing planes. Therefore, it is possible to provide the multi-plane electronic whiteboard apparatus with a simple structure and at a low cost.
