A US company claims to have come up with a way of thwarting pirates who tape films during cinema screenings.
Virginia-based Cinea is developing a system that manipulates the light levels of digitally screened movies.
While the shifting light levels will go unnoticed by the audience, it will make any illicit tapes unwatchable as the digital cameras used will not be able to guess the light levels correctly.
According to the BBC, the company has won a $2m grant from the US National Institute of Standards and Technology to develop a prototype.
Cinea believes that its invention will give film studios an opportunity to stamp out camcorder piracy.
There are currently only a few cinemas that show digital versions of films, and the numbers that can do so are not expected to rise significantly until 2004.
However, Cinea claims that it will eventually be able to cut film piracy by half.
