ABSTRACT:
A computer graphics apparatus and a method for allowing the comparison of two or more digitally-stored images on a raster-scan display device, such as a cathode ray tube (CRT), by use of arithmetic or Boolean logic operations performed on the picture elements (pixels) in each image which are to be superimposed at a given display pixel on the CRT. The invention provides the features of color lookup tables, continuous zoom and roam logic and high-speed processing in a computer graphics apparatus for digital image comparison.
