Description

A kind of method and apparatus automatically recording viewing number
Technical field
The present invention relates to the viewing numbers for automatically identifying when a kind of broadcasting film based on movie theatre and recording current play Device and method is related to automatically controlling and the fields such as display technology the present invention relates to image algorithm and image processing techniques.
Background technique
Currently, need to count accurate number and box office sometimes when cinema plays, then, existing side Method, is to rely on the film ticket sold more, and quantity is inaccurate.
In addition, it is known that movie theatre is inclined using the 3D of three optical paths or two optical paths (such as Le-vision 3D polarized systems) When vibrating system plays 3D film, it can effectively increase the brightness of 3D film in the case of not improving projector power, greatly Viewing quality is promoted, therefore has in movie theatre field and is extremely widely applied.The polarization liquid crystal light valve of polarization system exports projector Left-eye image polarization be right-hand circularly polarized light, right-hand circularly polarized light can only finally enter the left side of viewer by the left eyeglass of glasses Eye, and the left light of polarization liquid crystal light valve output will be ended by left eyeglass, and left eye is made to can only see corresponding left eye Image, and can't see image.Similarly, the left round polarization light that the right eyeglass of glasses can only be exported by polarization liquid crystal light valve passes through, And the right-hand circularly polarized light of polarization liquid crystal light valve output is ended left eyeglass, so that right eye can only see the right side that projector plays out Eye image, and can't see left-eye image.So that user watches accurate 3D film effect.
Summary of the invention
The purpose of the present invention is to provide a kind of method and apparatus for automatically recording viewing number.
It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken:
