A system and method of detecting and thwarting the use of unauthorized imaging systems at theatrical performances. Sensors (30) are deployed at a theatrical event to detect the IR focusing signal (22) and/or the RF signal of an unauthorized imaging device (20) . De-focusing signals (45) are used to disrupt the auto focus system of imaging devices that do not use IR focusing systems. A thwarting signal (40) comprising invisible light frequencies may be combined to produce a thwarting signal that is received by the CCD of an imaging device as white light thereby rendering the recorded image unusable.
SystEme et procEdE pour détecter et empêcher l'utilisation de systEmes de prise de vue interdits lors de reprEsentations thEAtrales. Des capteurs (30) sont dEployEs lors d'un EvEnement thEAtral pour dEtecter le signal de mise au point IR (22) et/ou le signal RF d'un dispositif de prise de vue (20) non autorisE . Des signaux de déréglage de mise au point (45) sont utilisEs pour perturber le systEme de mise au point automatique des dispositifs de prise de vue qui n'utilisent pas les systEmes de mise au point IR. Un signal d'empêchement (40) comprenant des frEquences de lumiEre invisibles peut Etre combinE pour produire un signal d'empêchement qui est reÇu par le CCD d'un dispositif de prise de vue en tant que lumiEre blanche, rendant ainsi l'image enregistrEe inutilisable.
