Positioning books for imaging and correcting distortion

摘要

An apparatus 2 for positioning a page of a book for imaging, comprises a support 8 for supporting the book with its pages open in a desired position, and a page positioning member 10 for positioning a page in an imaging position. The page positioning member 10 is movable from its page positioning position so as to permit a subsequent page of the book to be turned, the page positioning member 10 then being returnable to its page positioning position to allow the subsequent page to be positioned thereon. Also provided is a magnet (figure 3) with a transparent protrusion for locating a document. Further provided is a method and apparatus for correcting binding curvature distortion by imagining a pattern 66 placed in the gutter of the book and comprising this reference image to subsequent images of the book.
