Abstract
A video digital signal processing and display system that allows real time processing of video images with extensive filtering and inter-pixel interpolation. The system includes a front end user and program interface supported by a personal computer, and also includes a microprocessor for controlling the system and specialized video circuitry including an image translator. The image translator performs image translation, perspective projection, scaling, rotation, border insertion, and formation of composite images. The image translator interacts with the other specialized video circuitry which includes a frame constructor, a keyer and crosspoint switches, and a frame store constructor.
