Abstract

A digital imaging file processing system for processing and filing digitized documents is disclosed. In the preferred embodiment a distributed data processing system implements the invention and is comprised of a central computer linked to the following components: a document processor; optical character recognition device; mass storage devices; a printer; and at least one intelligent workstation computer. The document processor automatically digitizes a stack of documents without the need for user intervention. A unique header page is used in each group of documents to be digitized, and gives the document processor such pertinent information as the scanning resolution, whether the processor is to look for yellow highlight marks, and the copy quality of the documents in the batch. Other information includes instructions per the use or non-use of the optical character recognition device, and filing or indexing instructions. A unique yellow highlight mark detection method and means are disclosed. The method comprises illuminating the documents to be processed with light of different wavelengths and comparing the reflected output in volts. The highlight marks can be used to identify the title of a document as well as key words therein, and the location within the document of the highlighted regions. The digitized documents can be classified by title, key words or other methods.
