Abstract
A predominatly hardware-based system for rapidly generating overlay images by painting techniques using a host computer with appropriate graphics-generation operator interface, and for manipulating overlay images with respect to a background image. The system provides for rapid, convenient control of such imaging aspects as color alteration, repositioning the overlays on the background, and predetermining the amount of mask protection to be associated with each image pixel. The system can be readily realized, using available integrated crcuits, in the form of a host-computer plug-in accessory. A bidirectional multiple bus structure serves to interconnect the circuit boards, permitting convenient host-software-controlled configuration of the system.
