The human visual system sifts through an
enormous amount of data. Computer displays are less than life-like because
they don't present as much data. The challenge in providing a display
that matches the resolution of the human visual system is being able to
handle an enormous amount of information in real-time.
Researchers from Imaging Solutions Group and the National Aeronautics
and Space Administration (NASA) Ames Research Center have put together
a camera and display system that displays full-motion video at nearly
The system could provide a virtual window for various military,
aerospace, security and entertainment applications. The system's method
of capturing and displaying data could also be adapted to improve data
transmission and storage, according to the researchers.
The system's camera provides a video frame rate of 30 frames per
second at 8.3 million pixels, or four times the resolution of today's
high-definition television systems. The system uses 24-bit color and includes
an IBM 9.2-megapixel liquid crystal display. The system allows a person
with 20/20 vision standing half a meter away from the screen to see a
view that is arguably equivalent to looking through a window, according
to the researchers.
The researchers are working on finding compression schemes that
will allow them to stream the video signal over networks.
The camera can be used practically in six to nine months, according
to the researchers. The researchers presented the work at the Society
for Information Display (SID) International Symposium 2004 in Seattle,
Washington, May 23 to 28.
