Method and device for controlling video shooting

Abstract

The invention provides a method and device for controlling video shooting, and relates to the field of video images, wherein facial images of a speaker can be reserved, the number of times of video switch can be reduced, transition between the images is close, and an output video is smoother. The method comprises the following steps: when a first speaker talks, a first video camera device is controlled to shoot a video of the first speaker; when a second speaker replaces the first speaker and serves as the current speaker, a second video camera device is controlled to shoot a video of the second speaker, wherein the second speaker is a next speaker who stands at a position different from the first speaker; when speakers change later, the first video camera device and the second video camera device are controlled to alternately shoot a video of the current speaker; the video of the current speaker is output after being successfully received. The method and device for controlling video shooting are applied to video conferences.

Description

technical field [0001] The invention relates to the field of video images, in particular to a method and device for controlling video shooting. Background technique [0002] Generally, in a video conference, a camera takes panoramic pictures of all participants with a fixed size and a fixed angle. When the venue is relatively large, the camera may be far away from the speaker, and the captured images cannot determine who is speaking, and cannot see the speaker's facial expressions clearly, resulting in the loss of valuable information in the meeting. [0003] In order to avoid the loss of valuable information of the meeting caused by only taking panoramic pictures, two cameras can be used to take pictures of the venue at the same time. One of the cameras is always used to capture a panoramic view of the venue, and the other camera is used to track and capture the speakers. [0004] When people in the venue speak alternately, the video captured during this process is unstab...

AI Technical Summary

Problems solved by technology

[0004] When people in the venue speak alternately, the video captured during this process is unstable and uncomfortable to watch because the camera that tracks and shoots the speaker’s image needs to rotate / pull the camera before successfully obtaining the image of the current speaker. Need to switch to the panorama of the venue first

However, this switching will lead to loose connection of the pictures, and the video transmitted to the remote site will not be smooth, which will give viewers a very uncomfortable feeling
