Working in perfect coordination with the left- and right-eye images flashing on a 3D HDTV, active shutter glasses alternately blacken-out their liquid-crystal lenses at ultra-high speeds, ensuring that each eye only sees its intended image on the TV.
The new 3D
Casting aside the old red-and-blue technology of yester-year, today's 3D HDTV's look to alternate-frame sequencing (AFS) to achieve a 3D effect. Like all 3D technologies, AFS uses the same principles as does human sight to achieve 3D viewing. Our two eyes see a given object or scene from two slightly different angles, which our brains process into a single image with height, width, and depth...that is, 3D! Similarly, video cameras used to film AFS 3D movies use two lenses set slightly apart to record two almost-identical versions of a movie — one for your left eye and one for your right. These two versions are shuffled together, alternating single frames from each version, and 3D HDTVs play back that footage at ultra-high speeds while special active shutter glasses ensure that each eye sees only the version of the movie intended for that eye. Finally, your brain processes the two versions into one 3D feature presentation.
