Japan’s NHK is developing a new 3D TV system that viewers will be able to watch without needing special glasses.
According to NHK, it has achieved a higher-resolution 3D video system with HD TV-equivalent resolution (about two million pixels).
Aktina Vision captures an object from different viewpoints (horizontal and vertical locations) in order to obtain multi-viewpoint images. These are then used to reproduce the light rays from the object. NHK said that by increasing the number of the multi-viewpoint images and resolution of each image, natural high-resolution 3D video display can be achieved even when the viewer moves around horizontally and vertically in the viewing area.
The developed system accommodates 72 multi-viewpoint images, and using an 8K projector with a pixel-offset method increases the video resolution. A special optical system shifts and multiplexes the light rays of the images, leading to an increase in resolution from about 300,000 pixels produced by NHK’s previous system to about 2,000,000 pixels.
