Detection and obstruction of the contents signal which it occurs from theater performance

摘要

At the time of theater performing, use of the imaging system of non permission is detected and the system and the method of obstructing are disclosed. It arranges the sensor, in the theater event, the focusing signal of the imaging device of non permission and/or detects the RF signal. Making use of the dehuokashingu signal, it is confused the automatic focusing system of the imaging device which does not use the IR focusing system. Combining the obstruction signal which includes invisibility optical frequency, with CCD of the imaging device the obstruction signal which is received as white light is formed, the image which is recorded with that, is made use impossible. You remember emission shigunichiya of the imaging device in the data storage equipment, through network, you transmit to the user of the obstruction system. Emission shigunichiya the obstruction signal and association and detection system and the obstruction system, makes that you respond to the use of the imaging device of non permission quickly possible.
