Who wants to bet that this technology will be used whenever the riot gear is brought out, or whenever the State wants to keep prying media eyes away...

Digital camera blocking technology created

ATLANTA, June 19 (UPI) -- Georgia Institute of Technology scientists say they've created a prototype device that can block digital video cameras from working in a specific area.

The scientists say the prototype -- which could be used to stymie unwanted use of video or still cameras -- uses off-the-shelf equipment to scan for, find and neutralize digital cameras. The system works by looking for the reflectivity and shape of the image-producing sensors used in digital cameras.

Associate GIT Professor Gregory Abowd, who led the study, says the camera-neutralizing technology shows commercial promise in two principal fields -- protecting areas against espionage photography and stopping video copying.

Researchers explain a digital camera's image sensor -- called a CCD -- sends light back directly to its origin rather than scattering it, making it relatively easy to detect and identify video cameras.

Once a scanning laser and photo-detector located a video camera, the system would flash a thin beam of visible white light directly at the CCD, overwhelming the target camera with light and rendering recorded video unusable.

A paper on the technology, which is still under development, was presented during the Ubicomp conference in Tokyo last September.

they have to see the camera first. anyone with a high powered torch can do this already

i believe some movie theaters have something like this in place already, keeps people from making bootlegg copys.

as i understand it movie theatres pulse an infra red light not seen by the human eye onto cinema screens to interupt video cameras, this light is picked up by the video camera and appears as an annoying flashing on the recording.
