  • Patent number: 5134669
    Abstract: A method for extracting information from a document bearing (a) first indicia detectable in a first scan mode, using light in a first spectral range, but not detectable in a second scan mode, using light outside the first spectral range, and (b) second indicia detectable in either the first scan mode or second scan mode, where the second indicia represent information encoded in one or more forms decodable by automated symbol recognition resources, comprise several steps. One or more areas of interest on the document are defined in which the second indicia may appear, with the definition including information specifying the form of encoding for the second indicia. The document is scanned in the second mode, using a scanner that produces a pixel image of the indicia detected and the resulting pixel data are stored in a memory device.
