・Enrichment System ｆor Live Sports Broadcasts Using Real-time Motion Analysis and Computer Graphics [ BroadcastAsia2007 ]
Developed by NHK, this enhanced CG rendering systems make it possible to visualize the movements of players or balls in real-time by using image recognition technology. The system acquires favorable receptions from not only TV viewers but also commentators and producers because this visualization is also useful for the commentary.
・Development of a Compact Motion Control Camera System for HD Digital Broadcasting [SMPTE2005]
Developed by NHK, this new type of motion-control camera for use in HDTV production applies state-of-the-art Japanese industrial robotic technologies. As the HD camera itself is small, the system is compact. It also features a convenient user interface. Compatibility of the camera data with the popular Maya CG software makes shooting more efficient by enabling advance simulation of robotic motion. The ease of reproducing identical camera operations reduces the time required for multiple and CG compositions in VFX productions.
・Effective Interaction Tool in the Virtual Studio [IBC2002]
Developed by NHK, the Invisible Light Projection System is an interaction support system. Projector images are used to make virtual subjects visible in the studio, but invisible to the camera. Performers can see virtual subjects in a virtual studio, thus allowing natural engagement with the subjects including appropriate eye contact.
・HDTV Axi-Vision Camera [IBC2002]
Developed by NHK, the HDTV Axi-vision camera can acquire both an HDTV color image and a high-resolution depth image of a scene simultaneously. The depth detection system consists of intensity-modulated illuminators and a high-resolution CCD camera equipped with an ultra-fast shutter that uses a high-sensitivity image intensifier (I.I.). In real time the camera can selectively extract images of an object at a specific depth and synthesize them with other pictures. Potential post-production applications of the HDTV Axi-vision camera have been demonstrated in a virtual studio system.
