摘要： An image reading apparatus is capable of preventing generation of a streaked image or the like while maintaining the requisite precision level for the original reading position. The image reading apparatus includes a lead roller for supplying an original, a platen glass plate receiving the original supplied from the lead roller, a CCD for reading an image formed on the original supplied onto the platen glass plate, and a lead delivery roller for delivering the original after the reading of the image, in which there are provided between the lead roller and the lead delivery roller a plurality of platen rollers adapted to guide the original so as to keep it at a predetermined distance from the platen glass plate.

摘要： The present invention relates to the use of a camera and a structured light pattern in a platenless document imaging system (1) to capture the image of a page or of a bound book together with depth information that can be inferred from the light pattern. The imaging system (1) comprises a support surface (12) for a document (30) to be imaged, a light stripe projector (4) arranged to project a plurality of diverging sheets of light that extend from the projector (4) towards the support surface (12) for forming a series of stripes across the document (30), a camera (2) having a detector array (22) for capturing an image of the document (30) and of light stripes projected onto the document (30), a processor (25) arranged to receive (23) from the detector array (22) data representative of images of the document (30) and of the light stripes and to calculate therefrom a three-dimensional profile of the document (30) relative to a reference surface, wherein the relative divergence of adjacent sheets of light varies laterally across the sheets so that the stripes are concentrated where the divergence is relatively low.

摘要： 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.

摘要： A digital input scanner suitable for copying bound documents. The scanner comprises a scanner base portion, and a bound document support assembly attached to a top of the scanner base portion. The support assembly includes a generally horizontal top platen support surface and a plurality of exterior side surfaces. A digital scanning assembly is supported within at least a portion of the scanner base portion for acquiring an image of a portion of the bound document, and for generating an output digital signal representative of the acquired document face. The scanner components are arranged such that one of the exterior side surfaces of the support assembly has a canted surface, and the canted side surface and the top platen support surface form an oblique angle therebetween. The side surface and top surface are positioned to support opposing faces of the bound document during use.
