Embodiment approach

[0018] The electric actuator 3 is any actuating device used to be installed with the target device and act by electric drive, thereby driving the target device to move. Preferably, the electric actuator 3 can be a slide rail type, Vibrating or rotating. According to one embodiment of the present invention, the electric actuator 3 is a slide rail type actuator, including a slide rail and a slider that reciprocates on the slide rail, and the infrared laser 2 can be fixedly installed on the slider. The reciprocating movement of the sliding block driven by electricity can make the infrared laser 2 also reciprocate, so that the noise generated by the emitted infrared light on the shadow screen 4 will dynamically shift accordingly.

[0019] According to another embodiment of the present invention, the electric actuator 3 is a vibration-type actuator, the infrared laser 2 can be fixedly installed with the electric actuator 3, and the electric actuator 3 can be driven to vibrate by el...

Abstract

The invention discloses a device for preventing a film from being secretly filmed, the device comprising an infrared laser (2), an electric actuated piece (3). The infrared laser (2) fixed on the electric actuated piece (3) is used for emitting infrared lights to a screen (4). The electric actuated piece (3) is used for making the infrared lights emitted by the infrared laser (2) fixed on the electric actuated piece (3) generate deviation according to a received drive signal action. The method for preventing film from being secretly filmed comprises the following steps: a) using the infrared laser (2) to emit the infrared lights to the screen (4), the infrared laser (2) being fixed on the electric actuated piece (3); and b) driving the electric actuated piece (3) to operate, so as to make the infrared lights emitted by the infrared laser (2) fixed on the electric actuated piece (3) generate deviation. With the device and the method for preventing the film from being secretly filmed, piracy and secrete filming can be effectively prevented with high security and low cost.

Description

technical field [0001] The present invention relates to the application field of electronic technology, in particular to a film anti-piracy device and a film anti-piracy method. Background technique [0002] Due to the continuous development of camera technology, high-definition, small-sized micro-cameras are becoming more and more popular. It is very easy for movie pirate manufacturers to carry micro-cameras into movie theaters for sneak-camera piracy. economic loss. At present, it is obviously not enough to rely solely on artificial monitoring to prevent film piracy. Therefore, in order to destroy the illegal duplication of film pirate manufacturers, combat piracy, a kind of film anti-piracy device and a kind of film anti-piracy method are urgently needed. Contents of the invention [0003] The purpose of the present invention is to provide a movie anti-piracy device and a movie anti-piracy method that can destroy the illegal duplication of movie pirate manufacturers i...
