Abstract: DUAL DENSITY DIGITAL IMAGE SYSTEM A data processing system is disclosed for storing and displaying digital images, including a workstation having a document input scanner for digitizing document images at a first resolution, an image display unit for displaying digitized document images at a second resolution which is less than the first resolution and a printer for printing digitized document images at a third resolution greater than the second resolution. The system reduces communications traffic and assures fast access time on the network since the bulk of the traffic will utilize the smaller compressed data records required for the second resolution. However, these improvements in communication traffic and access time do not sacrifice the availability of high resolution compressed data records occasionally needed for printing and other high resolution operations.

Abstract: A method and apparatus which allows an object management and delivery system to perform capture, prefetch, display, print and/or modify operations with only a modicum of interaction between the operations of a host computer system and the object management and delivery system. Host computer/object-management system interaction is typically limited to: operation requests transferred from the host computer to the object management system; record registration data transferred from the object management system to notify the host computer that an object record has been stored; and/or error data transferred from the object management system to notify the host computer when the object management system encounters an error in trying to perform an operation requested by the host computer.
