Real-time operation for defocusing virtual objects

　Focusing and lighting effects play an important role in a filmmaking. 　It is also important to represent lens blur for effective scenes. We have developed a defocus operation in MR-PreViz system. 　This makes it possible to show us how the effects of defocused virtual objects are in real-time.
　In our method, the amount of defocus is computed from blur size and information obtained from a lens encoder. 　It generates proper blur for virtual objects same as real ones. Hence, Gaussian blur filter is used for a real-time processing.
