3D+2D TV: A hybrid to aid the floundering 3D craze?

3D+2D TV: A hybrid to aid the floundering 3D craze?

While I am not a big fan of 3D, I don’t mind an occasional dose of 3D viewing every now and again. It would be safe to say that there are a good number of people who share the same sentiment. On the other hand, there are also viewers who absolutely love 3D visuals and don’t mind shelling out extra for it. In practice, it means multiplexes and theaters screening both 2D and 3D versions of movies separately with the added cost of setup required. But what if both normal 2D images as well as 3D images can be viewed simultaneously on the big screen?

Researchers at the UCSC have come up with a 3D+2D image technology through which people wearing 3D glasses can enjoy 3D visuals while the ones not interested in 3D can experience the action with the naked eye without any ghosting. The prototype shows a normal 3D feed but also employs a third feed that can be viewed only by viewers without glasses. Before it gets confusing, let’s try and understand it through a flow pattern: –

  Standard polarized 3D feed + Additional 3rd (2D) feed  -> 3rd feed cancels right eye’s 3D image -> Viewers see just 2D image of left eye

In other words, this 3rd feed nullifies the 3D image that the right eye perceives and that leaves just the 2D image of the left eye which is viewed by users without the glasses.

But I am not sure that this development is the first of its kind. A little search on YouTube and I came upon this video by Kanagawa Institute of Technology (KAIT) in Japan who have a 2x3D real time shader technology by the name of “Multiplex Scritter” which operates on similar lines:



Regardless of who came first, I think there is a high level of viability in these developments as it will allow the projection technology in theaters to be cost-effective and audiences will also be able to watch a movie simultaneously in 2D or 3D as per one’s preference. I for one hope that it materializes and gets integrated in multiplexes and movie theaters as it might just be the saving grace of 3D visuals!
