Sony shows off 3D TV technology

The majority of existing 3D set-ups use two-camera systems to record images tailored specifically for the left and right eye of the viewer.
The new camera takes a single image that is split by mirrors and recorded on two sensors, resulting in a "smoother" picture, according to Sony.
The prototype camera will be unveiled at next week's Ceatec electronics show in Tokyo, Japan.
Viewers will be able to watch the 3D images using special polarised glasses. Without them, they will just see normal 2D television, according to the firm.
The firm said the camera, which is able to capture images very quickly, is especially suited to sporting events.
Sporting chance
There have been a number of forays into the 3D market, pioneered by the film industry.
In 1953 The House of Wax became the first commercial 3D movie. However, the early technology caused unsteady images that induced nausea.
A second attempt was made in the 1970s, using stereoscopic images that required users to wear red and green glasses; while the image was steady there was considerable loss of colour quality and it also failed to take off.

There are a number of stages to get live 3D TV into the home.


The latest revival, dubbed "The 3D Wave" kicked off in 2003 with the release of the film Ghosts of the Abyss.
Users now wear polarized glasses - rather than the standard red and green spectacle - with the resulting image "fooling" the brain into thinking it is 3D.
Meanwhile, the technology to capture in 3D - or create a virtual 3D image using conventional cameras - has also been getting cheaper and is now affordable by some traditional TV and satellite broadcasters.
