An image synthesizing technique called Synthevision is described. In this approach to image synthesis, a line NTSC camera foreground picture is synchronously keyed into a background picture which is digitally processed from a wide Hi-Vision image. This background-derived picture is controlled by a computer using data from the foreground camera. If the camera image is altered by actions of zooming, panning, and focusing, the background picture is altered accordingly through the use of a newly developed digital image processor. The combined image thus exhibits a far greater realism than conventional chroma-key imaging. Synthevision is currently used at NHK for the evening news to change the background for each segment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
