Abstract: The document scanner of the present invention includes a reading assembly of simple, compact and light-weight construction. The reading assembly includes an optical system having a relatively short focal length. The reading assembly is thus simply configured in a compact manner close to the document to be scanned. The optical system is also configured to extend in a particular direction beyond the document viewing area for improved resolution of images from a bound document adjacent the binding. The reading assembly further includes a compact and light-weight illumination source which is low in power consumption, and thus, may be powered by batteries. The stand-alone document scanner of the present invention is particularly suited to portability.

Abstract: An image reading apparatus is for reading a document such as a book from above with the target faces thereof placed upwardly. The apparatus allows for correction of distortions of the image, without relying on the background color of the target faces of the document. An image processing device detects the boundary between the document and a document-guiding device (the document edge) on the basis of the image read by the image reading device and corrects distortions of the image with reference to the detected boundary.

Abstract: A platenless book scanner with line buffering performs electronic perspective correction to account for rotation of the spine of a non-planar bound document relative to a reference line in a support plane of the platenless book scanner. A pre-scan of the non-planar bound document is performed to provide a geometrical contour map of the bound document. The geometrical contour map, which identifies displacement of the bound document from the support plane, is analyzed to calculate an angular offset between a spine of the bound document and the reference line in the support plane. The angular offset is used to identify a minimum number of scan line buffers for recording image data, from a set of scan line buffers. Once the minimum number of scan line buffers is filled with recorded image data, distortions caused by displacements of the non-planar bound document from the support plane and skew of the bound document relative to the reference line in the support plane are corrected. A scan line of image data is corrected by polling locations in the set of scan line buffers in accordance with the geometrical contour map, and by interpolating the polled locations to provide output pixels. To correct additional scan lines of image data some of the image data stored in the minimum number of image buffers is replaced after recording more image data.

Abstract: This invention provides a flat-edge scanner capable of scanning a thick book without any distortion at the protruding binding edge. The binding edge of the book is placed at the corner of a scanning glass window and the frame supporting the glass window so that the book can lie snugly over the window. The scanning window area is extended to the edge of the frame supporting the scanning window. All the optical system and the driving mechanism lie inside the boundary of the scanning window to increase the scanning range.
