<p>A movie antipirating scheme associates a detector with a screen and takes video and/or pictures of the audience. The detector can either detect something emitted by the camera or can find an image of a camera in the audience. An output indicative of the location of the probable camera can be used to find the person using the camera in the audience. E.g. by detecting his seat number if sitting down or location if the camera has been stashed somewhere. Most likely the camera is front and center to avoid obvious distortion in the features of the movie.</p>
