Abstract

The present invention discloses an image controlling method, device, and system for a composed-image video conference, where the method includes receiving audio data of sites; obtaining, according to audio data of each site of the sites and in real time, a voice feature value that is within a first specified period and of a corresponding site, where the voice feature value is used to represent an activation state of the site; selecting a specified site from the multiple sites according to an activation state of each site; and filling a picture of the specified site into a sub-image of a composed image, to update the composed image in real time. This remarkably improves an effect of a conference, and improves experience of participants. In addition, a quantity and locations of sub-images in the composed image may be further adjusted dynamically, which also effectively improves the effect of the conference.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a method, device and system for controlling pictures in a multi-picture video conferencing. Background technique [0002] In the video conferencing system, due to the large number of participants and their distribution in various places, in order to enable participants to communicate face-to-face with participants in other venues and to see participants in other venues at the same time, multiple conferences are generally used. With the technology of the screen, the participants can communicate with the participants in multiple venues at the same time by watching multiple screens. [0003] The current multi-screen display scheme of the video conferencing system is: pre-set the multi-screen mode, such as 4 screens, 9 screens, etc., and then fill several fixed sites into the sub-screens of the multi-screen, and each site can see it during the conference. All multi-screens are in t...
