Method, system, device and medium for adding station logo and generating video conference image

Abstract

The invention provides a station caption adding and video conference image generating method, system and device and a medium. The station caption adding method comprises the steps of acquiring the display size of each channel image in a video conference image; Obtaining the starting point position, the display content and the station caption size of the station caption needing to be added in the corresponding channel image; Judging whether the station caption exceeds the display range of the corresponding channel image or not according to the display size of the channel image corresponding tothe station caption; If yes, reducing the size of the station caption, and enabling the station caption to be located in the display range of the corresponding channel image; and adding the station captions into the corresponding channel images according to the station caption sizes, the display contents and the starting point positions. According to the invention, the authority of setting the size of the station caption is given to the user, the user is allowed to select the size of the station caption within a certain range, and the condition that the station caption can only display a partof the station caption or exceeds other channel terminal images is avoided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, system, device and medium for adding a station logo and generating a video conference image. Background technique [0002] A video conferencing system generally includes: a video conferencing terminal, a multipoint control unit (MCU for short), and other audio and video collection and output devices. Wherein, a multipoint control unit (Multi Control Unit, MCU for short) is an important part of the video processing platform. During the video conferencing process, various terminals call into the MCU for centralized management and control, forming a video conferencing network. Video processing is one of the important functions of the MCU. It is responsible for processing the video from each terminal, combining the videos of multiple terminals into a video stream with a predetermined resolution and sending it to each receiving terminal. [0003] In a multi-point ...

Problems solved by technology

In the existing system, due to the limited size of the synthesized screen, the size of the terminal screen of each channel is limited according to the synthesized style, so the size of the logo that can be displayed by each channel is also limited. In the past, in order to ensure that the logo can be displayed normally, The font size of the logo is not allowed to be set by the user. When adding the logo, a default font size will be calculated to generate the logo. Due to the algorithm and other reasons, the generated logo is too small, and the effect is often not ideal
