Abstract
Method for producing a background television image which moves corresponding to motion of a camera viewing a foreground scene, the image of which is to be combined with the background image by chroma-key, thus creating the appearance that both background and foreground are viewed by the same camera, although the background actually originates from separate cameras or recordings. Employs multiple cameras, or a single anamorphic camera with subsequent electronic horizontal expansion of the image, or recordings therefrom, to form the background image which can then be displaced in position, by variation of synchronizing pulse timings, while continuing to fill the full screen area. Also employs a backing for the foreground scene including a distinctive marker, the position of which in the foreground image is detected and used to control the position of the background image.
