Virtual Studio System for TV Program Production

Computer imaging techniques are playing an important role in TV program production. The authors have been studying a new program production environment called “Virtual studio system”(VSS), which enhances the freedom of image creation, with the tehniques of composing computer generated images and real images taken by video cameras. — General composing method may only be used to create efficiently composed images so far as no practical camera motion is necessary. But VSS is able to keep the relationship among these component objects, through changing camera parameters include zooming, panning, tilting and relocation, so that the composed images would look as if they were all same type of component images in a scene and shot with a single camera. — We have developed two types of VSS. One is “VSS driven by actual camera motion”, and the other is “VSS driven by virtual camera motion” which is further extended the concept of the former system.
