Single-Source Stereo and Microstereoscopic 3D

3DTV presents challenges: two lenses and cameras per shooting position, convergence operators and stereographers, graphics issues, ghost images, and false size perception or discomfort for viewers. Until 3DTV becomes the norm, events might be shot in both 2D and 3D versions. Addressing the discomfort issue, researchers have come up with something called “microstereopsis,” which, coincidentally, reduces or eliminates the other challenges noted above. Unfortunately, it also reduces the 3D depth sensation.

A similar situation once existed regarding stereo sound. Early TV-radio stereo simulcasts often used two different mixes for stereo and mono, and so-called “ping-pong” stereo once offered listeners a strong indication of the difference between stereo and mono.Today, however, stereo sound is usually captured with “single-source” techniques that are mono-stereo compatible. Beginning in 1881, stereo sound was compared to stereoscopic imagery. Might the single-source-stereo-like techniques of microstereopsis, therefore, be applicable to 3DTV?
