Problems solved by technology

[0002] Projectors are used in a wide range of applications nowadays. Projectors are mostly used in school classes, company meetings, vocational training and product launches. The function of the projector is to project images or videos such as PPT onto the screen. The speaker should combine Projected images or videos are used to explain. PPT generally contains less text and more content. Most of the content cannot be seen on PPT, and some content is not suitable for PPT. At this time, if you are interested in If the content is not very familiar, some reminder materials are needed. Some people use reminder cards from the lecture notes, etc., which will affect the lecture effect

Abstract

The invention discloses a projector system with an invisible teleprompter function and a data overlay processing method, including a projector, a subtitle superimposed device, a subtitle computer and polarized glasses; Perform superposition processing to form video data containing invisible subtitles, and output to the corresponding interface of the projector, and form a projection area on the imaging plane through the projector; after wearing polarized glasses, the hidden subtitles can be observed on the imaging plane, while Viewers without polarized glasses cannot observe the hidden subtitles on the imaging plane, and the video data on the imaging plane from the perspective of the audience is the same as that projected by an ordinary projector. The invention is reasonable in design and easy to use, and can be used as an ordinary projector Use, and at the same time, the function of prompting the speaker can be realized without affecting the viewing of the audience.
