Abstract: An optical text scanning device compatible with a small handheld computer such as a personal digital assistant (PDA). The scanning device allows for a clear view of the text that is scanned simultaneous to the scanning process so that the operator can continuously align the device to the text. The scanned images of the text are converted in real-time to standard byte or word characters for subsequent display on the computer's viewing screen. The operator can quickly verify the accuracy of the conversion by comparing the displayed character with the actual character of text on the surface that is being scanned. Scanned text characters are stored in standard digital text files for ease of manipulation.

Abstract: The present invention relates to a system for de-warping images of a developable surface, including developable curled surfaces, and in particular of images of curled documents (30). The system (1) includes a processor (25) linked to an image capture means (2) which: captures an image of the surface (30), said image having a warp corresponding to the non-planar surface; generates from the image a first set of points representing the three-dimensional profile of the non-planar surface relative (30) to a planar reference surface (12); fits to the first set of points a second set of points representative of a developable mesh; and uses the second set of points to texture-map the image (12) in order to de-warp the image.

Abstract: An electronic device includes a photodetector, a notification light emitter, and a determination component. The photodetector detects reflected light of light from a projection device within a detection region, the projection device projecting the light in a projection region on a projection surface. The notification light emitter emits on the projection surface two notification lines of visible wavelength that approach each other towards the photodetector. The determination component determines that the projection region is at least partially located outside the detection region based on a detection result of the photodetector. The determination component further determines that an edge of the projection region that is located closest to the photodetector is substantially parallel to a line segment that connects ends of the two notification lines.
