Problems solved by technology

There are different degrees of problems in the use of these methods, mainly as follows: First, if the file to be played is copied to the designated computer, not only will the reporter worry about the content leakage caused by leaving the report on the computer, but also may cause Viruses spread among each other due to the copying process; secondly, if different users use the same projector, when they are connected to different computers, it often causes a mismatch between the output signal of the computer and the projector, and it is often difficult to adjust it. Successful playback, time-consuming and labor-intensive, sometimes delaying work
For this problem, there is no good solution at home and abroad.

Embodiment Construction

[0016] Without using a video projector converter, the camera is directly connected to the projector through a video signal cable. Adjust the distance and angle between the camera and the display screen of the portable computer to make the projector display properly. Open a PPT file, adjust the focal length of the camera, and make the playing image information reach the best. The experimental results show that the image information played by this method is clearer, and the expected effect is achieved. The specific configuration is as follows:

Abstract

The invention relates to a connection method between a projector and a computer, which belongs to an image information transfer method. The invention is realized through the following technological scheme: step 1. Equipping a camera on a stretchable support; step 2. Adjusting the distance between the camera and the computer screen; step 3. Transferring collected signals to the projector immediately through digital wire, and the projector plays. The invention is simple in principle, low in cost, with time and energy saved and important data in computer loss avoided, realizing multiple effects.

Description

technical field [0001] The invention belongs to an image information transmission method, in particular to a connection method between a projector and a computer. Background technique [0002] Today, projectors are used more and more widely. On the one hand, due to the communication at all levels, and on the other hand, because its price is no longer very expensive, more and more home users purchase projectors to enjoy movies. At present, there are mainly two ways to connect the files in the computer to the projector to play. One is to copy the files to be reported into the computer connected to the projector through a mobile storage device, such as a U disk, and then play it by the computer; The way is to fix the projector and replace it with a different playback computer. There are different degrees of problems in the use of these methods, mainly as follows: First, if the file to be played is copied to the designated computer, not only will the reporter worry about the c...
