Virtual studio system for augmented reality & Chroma key processing

Chroma key image synthesis, out of Images A and B, makes transparent a specific scope of Image B and reflects Image A on it, and the chroma key which can synthesize an object with a desired background realizes an effect that the object seems to exist in that background. By combining real information with virtual information in this process and applying AR(Augmented Reality) technology to increase information delivery, an inexpensive and convenient HD virtual studio can be applied. That is, even though upcoming HD digital broadcasting service requires a shift from existing SD to HD resolution is required for HD digital broadcasting service, most of the HD equipments are expensive. Therefore, there are needed a low-priced HD virtual studio system which is being used only in public broadcasting network and a HD virtual studio system with chroma key applied.
