A new 3D+2D television provides 3D images for viewers wearing stereo glasses, and a normal, two-dimensional picture for those without glasses.


University of California, Santa Cruz (UCSC) researchers have created a 3D+2D television that offers three-dimensional images to viewers with stereo glasses while maintaining a normal, two-dimensional picture for those without glasses.

Current 3D TVs project a different image to each eye through stereo glasses, leaving viewers without the special glasses to see superimposed images that appear blurry, in an effect known as "ghosting."

The 3D+2D TV shows separate left and right images to viewers with glasses, but viewers without glasses see only the left image. A third image also is displayed that is the negative of the right image, which cancels that image out so that those without glasses see only the left image.

The researchers conducted several experiments to determine the optimal brightness ratio between right and left images, and they also conducted experiments to quantify issues with the depth perception of moving objects when one eye sees a darker image than the other.

UCSC professor James Davis developed the new TV along with several graduate students, and will present the technology at SIGGRAPH 2013 on July 25.
