| 内容記述 | This study aims to use original free-viewpoint live video technology in smart device applications to view objects in 360 degree 3-D. In 2013, the author used this technology to carry out the transmission of free-viewpoint video streaming of Sharp 4K TV's promotional website“AQUOS REAL LIVE”onto a PC. However, due to limitations in the OS design and specifications, there were difficulties in duplicating the editing and program systems present on the PC website’s video transmission when viewing them on smart devices. It was thus necessary to develop a new system. Therefore, the author devised a method of segmenting the film of an object, shot from 360 degrees with multiple cameras, into still frames, and then adding time and angle information to each frame. Smooth changes of viewpoint were attained by continually displaying these still frames with the time information and changing each corresponding angle in response to the user’s instructions. This made it possible to view a 360 degree 3-D video of objects even on smart device applications. This system also led to a free-viewpoint video with higher picture quality and smoothness, as the real image resolution and number of viewpoints are both unlimited. This technology was actually used in“Rittai Ikimono Zukan”(translated as“3-D Living Picture Book”), an application for smart devices that works in conjunction with the Benesse Corporation’s children’s television program“Shimajiro’s Wow!”It provided links between the television program and the educational content, which used free-viewpoint video. Moreover, this data system was included as an example of a patent acquired and implemented in Japan in 2013. In 2015, the rights to the same patent were acquired in South Korea, China, and the United States, and they are currently being applied for in Europe. |
