Device for controlling video image output, camera shooting equipment and conference system

Abstract

The invention discloses a device for controlling video image output, camera equipment and a conference system, which are used for outputting a video image result more accurately and reliably in practical application and improving user experience. The device for controlling video image output comprises a sound source positioning information receiving module, a target detection information receiving module, a sound and picture information recording and storing module and an output image calculating module. The sound source positioning information receiving module is used for receiving sound source positioning information and writing a sound source positioning processing result into the sound and picture information recording and storing module; the target detection information receiving module is used for receiving target detection information, reading data from the sound and picture information recording and storing module, determining an effective target detection result, and writing the effective target detection result into the sound and picture information recording and storing module; and the output image calculation module is used for reading the audio and video information from the audio and video information recording and storing module, and calculating and outputting a video image result according to the audio and video information.

Description

technical field [0001] The present application relates to the technical field of video image processing, in particular to a device for controlling video image output, camera equipment and a conference system. Background technique [0002] Nowadays, video conferencing has become more popular. At present, there are some intelligent conference systems on the market that can automatically give close-up pictures to the speaker in the video conference, so that other participants can clearly see the speaker's facial expressions and body movements. Greatly improved the meeting effect. [0003] Among them, how to determine the position of the speaker in the picture is particularly critical. In the prior art, some use array microphone sound source localization technology, and some use image recognition technology (such as portrait detection, mouth opening and closing degree judgment, standing motion detection, face motion information recognition, etc.), and sound source localization ...

Problems solved by technology

[0004] However, in actual scenarios, since the sound source localization module and the target detection module are independent of each other, there are usually different degrees of delay, especially when the two modules work on different platforms, the delay difference will be greater, which will affect the video quality. The final result of the image output greatly affects the user experience
