I don't belve this is (completly) correct regarding the visible 3D image (only technical numbers).
Read Sharpness and Resolution with FPR Passive Glasses
By far the most controversial and misunderstood issue in 3D TV currently has to do with the sharpness and resolution delivered with Passive Glasses. Because they split the odd and even lines between the right and left eyes it's easy to see why many people (and some reviewers) conclude that FPR technology delivers only half of the HD resolution.
Although unsubstantiated it still seems to have evolved into some sort of myth based on hearsay instead of actual scientific visual
evaluation. Many people seem to get stuck on this particular issue and can't get beyond it and think about what is really being seen in actual 3D vision.
But it's not that simple because we watch TV from a far enough distance that the lines are not resolved and we know that the brain combines the images from both eyes into a single 3D image (the one we actually see) in a process called Image Fusion
. The 3D TV images have only horizontal parallax from the horizontally offset cameras, so the vertical image content for the right and left eyes are in fact identical
- but with purely horizontal parallax offsets
from their different right and left camera viewpoints. So there isn't any 3D imaging information that is missing because all of the necessary vertical resolution and parallax information is available when the brain combines the right and left images into the 3D image we actually see.In all cases the small text (6 to 10 pixels in height) was readable on the FPR Passive Glasses, which definitively establishes that there is excellent 3D Image Fusion and the Passive Glasses deliver full 1080p resolution in 3D.
Again, if the Passive Glasses only delivered half the resolution, as some claim, then it would have been impossible to read the small text on the FPR TVs. So those half resolution claims are manifestly wrong - no, ands ifs or buts!
Furthermore, in all cases the small text was actually sharper and easier to read and fine details easier to resolve on the FPR Passive Glasses than on the Active Glasses because of the Crosstalk, ghosting and Response Time issues that reduce 3D image sharpness and 3D contrast in Active Glasses TVs.
We also compared the small text 3D visual sharpness to the 2D sharpness by repeatedly turning the 3D mode on and off for each of the TVs and watching in 3D with glasses and then 2D without glasses. In all cases the images were sharper in 2D than in 3D, but the differences were much smaller with the FPR TVs than with the TVs with Active Shutter Glasses. In fact, the small text 3D visual sharpness on the FPR TVs were only slightly less than in 2D
, reinforcing our conclusion that the Passive Glasses deliver 3D Image Fusion with full 3D 1080p resolution and are visually sharper in 3D than Active Glasses because of the Crosstalk, ghosting and Response Time issues mentioned above.
