Video processing system

Image Number 3 for United States Patent #5107252.

A video processing system for use in combining a first video image sequence comprising a number of image frames and a second sequence of video image frames to create a composite video image sequence is disclosed. The system comprises a stylus and touch tablet combination and is arranged to define on a frame-by-frame basis at least four reference points representing corners of a keyframe in three dimensional space notionally projected onto a monitor screen. A transforming circuit transforms the addresses of pixels in a frame of the first video image sequence so as to cause the pixels to represent the frame as projected onto the display screen from the same location in three dimensional space as the keyframe. A combiner combines the transformed frame with a corresponding frame of the second video sequence to produce the composite video image sequence.
