Description
Technical field
The utility model relates to the application of electronic technology field, particularly, relates to the anti-pirates shoot device of a kind of film.
Background technology
Because the continuous development of camcorder technology, high-resolution, the microcam that volume is little are more and more universal, movie piracy manufacturer carries microcam and enters and carry out piracy in the cinema and take on the sly very easy, make that the movie piracy phenomenon of taking on the sly is serious day by day, caused enormous economic loss for relevant industry.Only monitor artificially at present and prevent that the obvious dynamics of film pirates shoot is not enough.Therefore,, combat copyright piracy, need a kind of film to prevent the pirates shoot device urgently in order to destroy the bootlegging of movie piracy manufacturer.
The utility model content
The purpose of this utility model is at the present cinema piracy serious problem of phenomenon of taking on the sly, and a kind of anti-pirates shoot device of film that can destroy the bootlegging of movie piracy manufacturer is provided.
To achieve these goals, the utility model provides a kind of film to prevent the pirates shoot device, should comprise infrared laser and electric actuation spare by anti-pirates shoot device, described infrared laser is installed on the described electric actuation spare, described infrared laser is used for to shadow curtain emission infrared light, described electric actuation spare is used for according to the drive signal action that receives, and makes the infrared light that is installed in the infrared laser emission on the described electric actuation spare produce dynamic deflection.
The technical scheme that provides according to the utility model can be installed in the anti-pirates shoot device of described film near the appropriate location the shadow curtain, as long as make the emergent ray of infrared laser can be transmitted on the shadow curtain.During movie, can be by infrared laser to shadow curtain emission infrared light, because infrared light wavelength has exceeded (visible light) scope that human eye can be discerned, make spectators to discern, therefore can not exert an influence to the audience ornamental film, but the CCD light sensation device in video camera and the camera can be filmed infrared light, during broadcast as seen.Therefore, enter movie theatre, can produce the interference noise that infrared ray forms in the captured movie pictures, will have a strong impact on shooting effect if there is the people to carry apparatus for making a video recording.And, by driving the electric actuation spare action of installing with described infrared laser, can be so that the infrared light of infrared laser emission produces skew, make the interference noise generation dynamic deflection that infrared light produces thus in movie pictures, like this, the film viewing effect that obtains of taking on the sly is poorer, can't make pirated film and sell.
The anti-pirates shoot device of the film that adopts the utility model to provide can destroy the bootlegging of movie piracy manufacturer, prevents that effectively piracy from taking on the sly, and is safe and with low cost.Other feature and advantage of the present utility model will partly be described in detail in embodiment subsequently.
