Abstract

We present a new video projection technique to defeat camcorder piracy in movie theaters using the newly emerged display paradigm of temporal psychovisual modulation. The technique exploits the difference in image formation mechanisms between human eyes and digital cameras: in the human visual system, images are formed via continuous integration of the light field, whereas digital video acquisition is based on discrete sampling of light sensors. A movie frame is decomposed into multiple so-called shale frames such that, when these shale frames are displayed at a frame rate higher than 60 Hz, the human viewers will experience normal movie presentation without any noticeable artifacts, but the video frames captured by camcorders will contain severe, highly objectionable artifacts, depriving the pirated video contents of any commercial values.
