Abstract:
An apparatus for processing a document having a front face, the document being receivable in different orientations, comprising:a) a document transport for conveying the document along a selected path of movement;b) an optical scanner positioned along the selected path for optically reading the document, the scanner generating a set of data corresponding to light levels at discrete positions on the document;c) an image processor responsive to the data generated by the optical scanner, the image processor including a density detector for determining a density count at a selected area on the document, the density count representing the number of discrete positions in the selected area having a light level above a selected light threshold; andd) an orientation detector responsive to the density detector for determining that the document is in a first predefined orientation, or that the document is in some other orientation different from the first orientation.
