ABSTRACT:
A system which allows for the generation of grayscale video signals from color graphics images to grayscaling display devices receiving digital signals. The system is implemented advantageously in packed pixel color graphics modes of a video graphics array sysem utilized in a personal computer. The system is preferably implemented in a software program to decrease the number of hardware components, save circuit board space, consume less power and reduce complexity in the circuitry in the personal computer.
