Patent Images
1. An archival document image storage and retrieval system for storing image information representing the content of a plurality of archival documents, maintaining an index of descriptive terms and documents, and retrieving stored image information corresponding to a particular document in accordance with said index upon identification of a corresponding descriptive term, said system comprising:
- a camera for generating electronic digital output signal representing the image of a document;
data processing means for providing a processor output representing both said image and index information corresponding to said document, said data processing means including means for receiving and storing said digital output signals from said camera representing a plurality of document images, means for retrieving said stored images from said means for storing after said digital signals representing said plurality of document images have been stored, means for recognizing the content of the images retrieved from said means for storing and producing recognition results, and means for generating said index information in accordance with said recognition results to thereby obtain said processor output; and
digital optical storage means for optically recording said processor output.

Abstract
A digital camera is used to scan documents and generate a corresponding digital output signal. A data processor receives the digital output signal and generates corresponding index information. The video and index information are then stored on one or more optical disks for search and retrieval.

7. An archival document image storage method for storing image information representing the content of a plurality of documents, maintaining an index of descriptive terms and documents for subsequent retrieval of stored image information corresponding to a particular document in accordance with said index upon identification of a corresponding descriptive term, said method including the steps of:
-
generating with a camera a succession of electronic digital output signals representing the images of a corresponding succession of documents; recording said succession of digital output signals on a first storage medium; after said succession of digital output signals have been stored, reading said succession of digital output signals from said first storage medium; receiving said read digital signals in a data processing means, recognizing the content of at least a portion of said digital output signals from said first storage medium and producing recognition results, generating index information corresponding to each document in accordance with said recognition results and providing a processor output representing both the image of each document and the generated index information corresponding to each document; and optically recording said processor output. - View Dependent Claims (8, 9)
