High-density Electronic Imaging: Developments and Limitations

Paul A.H. Pankow

High-density electronic imaging (HDEI) means different things to different people. For some, electronic imaging simply refers to computerized word processing; others see electronic imaging as part of a complex system capable of moving huge blocks of imaging data at high speeds. There are three basic types of data flows to consider: • A bit-stream data flow that allows one computer to communicate and share data with another; • A graphics data flow that incorporates systems such as word processing and desktop publishing; and • HDEI for medical, photographic, and reprographic applications.
