A Video Display System for Image Processing by Computer
February 1973 (vol. 22 no. 2)
pp. 128-134
N.H. Kreitzer, IBM T. J. Watson Research Center
A core-refreshed video display system that can display gray-scale images of 32 intensity levels on a standard monochrome video monitor will be described. The system can also display flicker-free black and white images of more than 800 000 picture elements. There are special features that allow overlaying black and white images on 16-level gray-scale images and manual cursor control via an X-Y tablet. Multiple reduced size images can be accommodated by features that allow independent manipulation of images in separate areas on the display screen. This permits simultaneous display of images before and after processing.
Index Terms:
Cathode-ray tube display, computer display, cursor, graphics, graphic tablet, image overlay, image processing, image refresh buffer, raster display, video display.
