目前已经研究出一种被称为“虚拟演播室系统”(Virtual studio system—VSS)的节目制作环境。VSS的出现使合成计算机产生的图形和摄像机摄取的真实图像为一画面从而产生生动的新图像的自由度大增。 目前有两种VSS方式。一种称作“实际摄像机移动VSS”(VSS—AC);另一种是“虚拟摄像机VSS”(VSS—VC)。 VSS—AC是这样一种方法:实际演员表 A program production environment known as “Virtual studio system” (VSS) has been developed. The advent of VSS has increased the degree of freedom in synthesizing computer-generated graphics and camera-captured real images as one screen to produce vivid new images. There are currently two VSS modes. One is called “Actual Camera Move VSS” (VSS-AC); the other is “Virtual Camera VSS” (VSS-VC). VSS-AC is one such method: the actual cast
