Abstract

Bitmapped images of high resolution, say 300 dpi rastered documents, stored in the memory of a PC are at best only borderline readable on the PC's display screen (say a 72 dpi VGA monitor). Results from a series of exploratory psycho-physical experiments, using the Adobe Photoshop^R software, show that the readability can be significantly enhanced by making use of the monitor's capability to display shades of gray. It is suggested that such a gray scale adaptation module should be bundled to all software products for electronic document management. In fact, fax modems are already available in which this principle is employed, hereby making it possible to read incoming fax documents directly on the screen.
