Cameras Strictly Prohibited

I know most cinemas specially Ayala malls strictly prohibits still or video cameras inside movie houses. Obviously trying to prevent piracy. But can a still camera like my digital eos (no video or sound recording capability) can do movie piracy? If yes, i don't know how. So I though its not practical to surrender my camera.

And above is what i got hehe... shadowy image of Emma Watson. The timing is just bad.
