A line scanning system controlled from an on-line console

Abstract

Direct graphical input is one of the newest and most exciting sources of digital computer input. Programming techniques and hardware are beginning to appear which are designed to automatically process graphic information. This paper describes an experimental system which has been designed to facilitate the digitizing of line images. The equipment which is used for this purpose is an IBM 7960 Special Image Processing System consisting of graphic console, image processor, and a modified data channel. The image processor (Figure 1) contains a programmable Cathode Ray Tube (CRT) scanner, a CRT recorder, a 35mm camera, and film processing equipment.
