The video revolution — or why the 1990s will be the decade of the image in the information industry

Abstract

The 1970s and 1980s saw the rise and rapid development of online textual databases, particularly those covering science and technology. Online patents files are amongst the most used of these databases, and are now accessed worldwide by both patent specialists and researchers. However, most online databases covering intellectual property are based on an original document or publication which includes highly meaningful drawings, chemical structures or diagrams. Until recently these have not been available in electronic format. The recent rapid advances in image handling and distribution technology, such as Document Image Processing (DIP), image extraction, CD-ROM, WORM discs, erasable optical discs, high speed laser printing, and the delivery of images over high speed telecommunications networks or by Group 4 fax, will enable the next generation of information products to be developed during the 1990s. The ability to mix searchable text with corresponding images, held either locally or delivered online, will enable the benefits of the original printed document or product to be made available to users in an electronic format. Since images are such a key element in making the most effective use of patent information this will mean that patent information products will be amongst the first to experience this image handling revolution. This paper reviews some of the present developments in image handling, and speculates on what kinds of information tools might evolve during the decade.
