No! The seven minute video is playing in half
of a gallery room. The room is divided in half by
the wall that holds the rear projection screen.

The screen is similar to the QD Black
Screen seen at CES in Las Vegas.
and the Annual Stereoscopic
Displays and Applications conference in San Jose.
So there was no way to see the actual
system showing the video.

In Las Vegas they showed a real-time 3D video
image viewable with circular polarized glasses.
They were using a Toshiba 3D cameras and handing
glasses to passersby so they could see themselves
in 3D. The display made use of the "3D Black
Screen" material developed at QD which allows
polarized 3D rear projection.
QD Technology is located at 536 N.
Santa Cruz Blvd. #201, Los Gatos,
CA 95030; phone (408) 354-0650

In San Jose the presentation with the QD
7500 Professional Stereoscopic
Video Enhancement Processor was
unbelievable. First, the Titanic
footage was a dual Beta source.
But the QD7500 doubles the lines
from the input to give a flickerless
full color RGB video at 120 Hz
vertical rate, creating a separate 60
Hz field for each eye. The system
interpolates a new line between
each pair of lines not just a
replication of each line. The image
quality is then improved by digital
signal processing, adapting on a
sample to sample basis providing
edge enhancement, noise reduction
and artifact removal. The image
was shown on the large rear
projection QD black screen,
viewing was with standard
polarized cardboard glasses.

At the LA County Museum of Art, the image
is good, but not as good as the Titanic footage.
Perhaps they are just using an alternate-field
video source. The video titled Nirvana (1997)
is courtesy of Deitch Projects, New York and
Gallery Koyanagi, Tokyo.

Thanks for the time,
