    "abstract": "In this study, we investigate three-dimensional (3D) video technology based on spatial imaging to implement a next-generation broadcasting service. This technology allows viewers to watch 3D videos without the need for specialized glasses. However, the main challenge associated with the application of this technology is the large amount of ray information that needs to be acquired and reproduced to improve the quality of the 3D videos. Therefore, we are in the process of actively developing methods to acquire high-density ray information from multiviewpoint images, captured using a multicamera system; in addition, we are devising 3D display methods using multiple display devices. In this paper, we present the most recent results of our research regarding 3D television technologies, including a prototype system based on our novel display method called “Aktina Vision.” This system can reproduce 3D videos of real objects at a resolution of approximately 330,000 pixels, three times that of conventional full-parallax spatial imaging methods using a lens array.",
