 note = {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.},
