Embodiment Construction

[0049] The present invention provides an image processing method and system in video communication. Using DirectX image processing technology, full-screen display of video images and fast switching between full-screen and original windows are realized in video communication, and the process of full-screen display is reduced. The utilization ratio of CPU in the middle, the technical conception of the present invention is as shown in Figure 2, comprises:

[0050] 1. When the user starts the video communication management module, the video communication management module creates the original window and stores it in the display memory, and then calls the DirectX image processing module to send the original window position information and magnification to the DirectX image processing module. At this time, the magnification If it is set to 1, the video communication management module acquires and decodes the data frames frame by frame and then inputs them into the DirectX image proce...

Abstract

The invention relates to a window switch control method of video image and relative system, wherein said method comprises that: based on user full-screen display switch operation or original window display operation, building relative video window; using video processing module to amplify or reduce the video into video window to be displayed. And the system comprises user operation command picker, video communication manager, display memory, display module connected to the display memory, and the video processing module connected between memory module and video communication manager. The video communication manager also comprises user operation command recognizer sub module, window manage sub module. The invention can realize full screen display of video communication and quick switch.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for controlling window switching of video images in video communication. Background technique [0002] As shown in Figure 1, in video communication, video data is transmitted in the form of video data frames, and each frame is equivalent to a video picture. After the video data is acquired, each frame of video data is decoded, and then the data Displayed graphically. [0003] Among the existing video communication applications, video communication is a very wide application. For users, what they directly face is the view quality displayed in video communication. Therefore, in this regard, all major video communication software are working hard. Improve its technology in order to achieve a clearer display and a better user experience. In terms of technical implementation, it is usually necessary to do a lot of processing on video images to obtain high-quality image...
