Pixim DEMO Report

Have you ever wondered how experts trying to track
criminals can identify them using footage from security cameras? From
my vantage point, the picture is always so grainy, it's a wonder they'd
ever stand up in court. Pixim, a semiconductor and software imaging
company, launched a new video imaging system that turns the stereotype
on its ear.
In his demonstration of the D2000 Video Imaging System, President and
CEO Bob Weinshenk showed the audience a picture of a casino table.
There on the table were blackjack hands and some chips. On a
"traditional" security camera, the chips are a bit blurred. On the
Pixim system, Weinshenk showed that one chip had a red mark on the
edge, also illustrating how much clearer the Pixim system is. Weinshenk
claims this is because the camera deals with dynamic light ranges,
adjusting to get a clear image no matter what the lighting situation.
The Pixim system encodes each pixel of the image at is "optimum
exposure," constantly comparing in real time how the image should look.
