Method for modifying a visible object shot with a television camera

摘要

A method for modifying a visible object shot with a television camera, in which method the object is marked by one or more marking surfaces disposed in the area of the object or in its vicinity, these marking surfaces being identifiable on the basis of radiation differing from other radiation in the area being shot. At least one of the marking surfaces differs in radiation from the environment on the basis of a property other than the color of visible light. The marking surface is identified using at least one identifying detector which is separate from the detectors of the television camera and by means of which the object is shot substantially from the same shooting direction as the picture shot by the television camera.
