Method for sharing handwritten image on screen in video conference and terminal for carrying out video conference

Abstract

The invention relates to a method for sharing a handwritten image on a screen between terminals which carry out a video conference and the terminal for realizing the method. The method comprises the steps of displaying a background composite image layer on a touch display screen of one terminal; displaying a video conference window image layer of the terminal on the touch display screen of the terminal, and displaying an output image of the other terminal in the video conference window image layer of the terminal; and carrying out handwriting input and generating a handwritten image layer on the touch display screen of the terminal, combining the background composite image layer and the handwritten image layer in real time, then taking the combined image layer as the output image of the terminal, sending the output image of the terminal to the other terminal, and displaying the output image in the video conference window image layer of the other terminal.

Description

technical field [0001] The invention relates to the field of information sharing in multimedia communication, in particular to a method for sharing handwritten images during video conference and a terminal for video conference. Background technique [0002] Communication systems allow users of devices to communicate over a computer network, such as the Internet. Communication events that can be established include voice calls, video calls, instant messages, voicemails, file transfers, and others. With the above communication system, when one user communicates with another user, the content on their screen can be shared. In the scenario of using the existing communication system, for example, when using the communication system to hold a video conference, an electronic whiteboard device is often additionally set up to realize handwriting interaction. mark, and display these handwritten marks on both the computer and the electronic whiteboard. Most of these types of systems...

[0004] However, in this integrated interactive whiteboard and video conferencing system, because the integrated touch screen is also used as a display screen for displaying the video conference window and a handwriting input screen for the electronic whiteboard, users can only use it intermittently in time or space. The electronic whiteboard function and the screen display function of the video conference, that is, when the user's screen displays the video conference window and obtains the information shared by the user of another terminal through the video conference window, only the screen other than the video conference window Part of it is used as a handwriting input area, which is small and inconvenient to use; on the other hand, if the user wants to use the entire area as an electronic whiteboard input area, the video conference window cannot be displayed on the screen at the same time to obtain another terminal. Otherwise, the superimposition of the video conference window and the handwritten input content will affect the readability of the information received by the user of another remote terminal
