Researchers use projectors for 2D and 3D screen

Researchers from the Shirai Lab at the Kanagawa Institute of Technology in Japan, have developed a screen that displays both 2D and 3D images at the same time via the medium of projection technology.

The screen was designed in response to the current 3D televisions, which often lead to headaches and eye-strain if viewed without the correct polarising or shutter glasses.

Unlike these common 3D televisions, the new screen is able to produce both a 2D and a 3D image at the same time without any undesirable side effects or distortion in picture.

Powered by two projectors that are designed to work in tandem, the 2x3D display creates the image using complex image algorithms, which are then processed in real-time by a GPU.

Although the projectors still create two images, the clever colour mixing techniques designed by the researchers enable normal 2D viewing for those without 3D glasses.

The researchers hope that their 2x3D projection and screen technology will become useful for many applications, including language translation signage that's translated into multiple languages with the use of special 3D glasses. However, the drop in image quality between the 3D and 2D images mean that the home theatre market may be out of reach for the foreseeable future.
