Abstract

Abstract A digital imaging file processing system for processing and filing digitized documents is disclosed. In the preferred embodiment a distributed data processing system (200) implements the invention and is comprised of a central computer (202) linked to the following components: a document processor (206); optical character recognition device (208); mass storage devices (210, 212); a printer (214); and at least one intelligent workstation computer (216). The document processor (206) 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.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 57 words
A digital imaging file processing system for processing and filing digitized documents comprising: scanner means (530, 532, 534, 536, 538) for scanning and converting a group of input documents into digital image data; storage means (210, 212) for storing digital image data; and detection means (402, 404) for detecting and storing highlighted areas on the input documents.
Claim 2
Dependent Claim 57 words
A digital imaging file processing system for processing and filing digitized documents comprising: scanner means (530, 532, 534, 536, 538) for scanning and converting a group of input documents into digital image data; storage means (210, 212) for storing digital image data; and detection means (402, 404) for detecting and storing highlighted areas on the input documents.
Claim 3
Dependent Claim 142 words
The digital imaging file processing system of claim 1 wherein said detection means further comprises: first illumination means (528) for illuminating said input documents with light of a first illumination quality; second illumination means (528) for illuminating said input documents with light of a second illumination quality; output comparison means which obtains a comparison value from comparing at each predefined cell of pixels, the difference of potential output of the first illumination means with the difference of potential output of the second illumination means; and thresholding means for thresholding at each cell, the result of said output comparison means and determining the presence of highlighting in the cell if the comparison value is greater than or equal to a predefined threshold value, while determining the non-presence of highlighting in the cell if the comparison value is less than the predefined threshold value.
Claim 4
Dependent Claim 28 words
The digital imaging file processing system of claim 2 further comprising: highlight mark shape assimilation means (402, 404) for assimilating detected highlight marks into a combination of rectangles.
Claim 5
Dependent Claim 48 words
The digital imaging file processing system of claim 3 further comprising: highlight mark shape determination means (402, 404) for determining the shape of said detected, assimilated highlight marks, whereby the highlighted indicia on the documents are given special treatment by the system according the corresponding highlight mark shape.
Claim 6
Dependent Claim 72 words
A digital imaging file processing system for processing and filing digitized documents comprising: scanner means (530, 532, 534, 536, 538) for scanning and converting a group of input documents into digital image data; storage means (210, 212) for storing digital image data; and header page means (600) associated with each group of documents to be digitized for automatically instructing the operation of the system with the use of a coded header page.
Claim 7
Dependent Claim 72 words
A digital imaging file processing system for processing and filing digitized documents comprising: scanner means (530, 532, 534, 536, 538) for scanning and converting a group of input documents into digital image data; storage means (210, 212) for storing digital image data; and header page means (600) associated with each group of documents to be digitized for automatically instructing the operation of the system with the use of a coded header page.
Claim 8
Dependent Claim 42 words
The digital imaging file processing system of claim 5 wherein said header page includes instructions relating to the control of the scanner means, control of the storage means and the use, non-use and nature of use of an optical character recognition device.
Claim 9
Dependent Claim 40 words
The digital imaging file processing system of claim 1 further comprising: header page means (600) associated with each group of documents to be digitized for automatically instructing the operation of the system with the use of a coded header page.
Claim 10
Dependent Claim 42 words
The digital imaging file processing system of claim 7 wherein said header page includes instructions relating to the control of the scanner means, control of the storage means and the use, non-use and nature of use of an optical character recognition device.
Claim 11
Dependent Claim 30 words
The digital imaging file processing system of claim 9 further comprising: optical character recognition means (208, 418) for converting said digital image data into alphanumeric characters to form text data.
Claim 12
