Projector with function of camera and shooting method

Abstract

The invention discloses a projector with a function of a camera and a shooting method. The projector comprises a projecting module, a camera module, a sound receiving module, a switch module, a processing module and a storage module. The switch module controls the projecting module, the camera module and the sound receiving module simultaneously. The processing module is connected with the camera module and the sound receiving module and used for receiving video and audio signals, compressing the video and audio signals to video streams of specified formats, and outputting the video streams. The storage module is used for storing the video streams output by the processing module. By the projector with the function of the camera and the shooting method and combining the camera function with the projecting function, shooting cost is lowered compared with specialized cameras. In addition, the projector is convenient to operate and brings great convenience to activities such as teachings, meetings and speeches.

Description

[0001] 【Technical field】 [0002] The invention relates to a projector, in particular to a projector with a camera function and a shooting method. 【Background technique】 [0003] Nowadays, projectors have been widely used in teaching, training and conferences. It can project the content that the speaker needs to explain onto the screen. Although the application of the projector has brought great convenience for people, there are still the following weak points: [0004] First, the speaker cannot see his own performance on stage; [0005] Second, for some people who are absent from class or unable to attend the meeting due to special reasons, although they can make up for the content of the course or meeting by copying courseware or lecture notes, due to the lack of audio-visual effects, they cannot see the speaker's body language and cannot listen to it. There is no speaker and on-site interactive voice, so there is no immersive effect; [0006] Third, to shoot the whole...

Problems solved by technology

[0004] First, the speaker cannot see his own performance on stage;

[0005] Second, for some people who are absent from class or unable to attend the meeting due to special reasons, although they can make up for the content of the course or meeting by copying courseware or lecture notes, due to the lack of audio-visual effects, they cannot see the speaker's body language and cannot listen to it. There is no speaker and on-site interactive voice, so there is no immersive effect;

[0006] Third, to shoot the entire teaching, training and meeting process, the usual method is to use a camera to take pictures, which requires special camera equipment and camera personnel, the cost is relatively high, and the operation is quite cumbersome and extremely inconvenient

[0007] In summary, existing projectors and projection technologies need to be improved and developed urgently.
