Invisible word proposing projector system and video data processing method

Abstract

The present invention discloses an invisible word proposing projector system and a video data processing method. The system comprises a light source, a first convergence mirror, a color wheel, a second convergence mirror, a digital micro-mirror, a digital micro-mirror driving module and a lens, and further comprises a frame synchronization signal transmitting module, liquid crystal glasses, a subtitle data generation module, a video data generation module and a subtitle superposition module. The video data is processed through a subtitle superposition module, the processed video data is projected to a lens by a digital micromirror, and a projection area is formed on an imaging plane; after the liquid crystal glasses are worn, hidden subtitles can be observed on an imaging plane, audienceswithout liquid crystal glasses cannot observe the hidden subtitles on the imaging plane, the projection effect of the video data on the imaging plane under the view angle of the audiences is the sameas that through a common projector; and the design is reasonable, the use is convenient, the projector can be used as a common projector, the function of giving words to a speaker can be realized, andthe watching of the audience is not influenced.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to an invisible teleprompter projector system. Background technique [0002] Projectors are now widely used in a wide range of applications. Most of them are used in school classes, company meetings, vocational training, and product launches. The function of the projector is to project PPT and other images on the screen. Using images to explain, PPT generally contains less text and more content. Most of the content cannot be seen in PPT, and some content is not suitable for PPT. If you are not familiar with the content at this time , you need some reminder materials, and some people are holding lecture notes and reminder cards, etc., which will affect the lecture effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an invisible teleprompter projector system that is reasonable in design, easy to use, can be used as...
