摘　　要：颜色空间是一个三维坐标系统,每一种颜色由一个点表示。RGB与YUV分属于不同的颜色空间,且两者之间可以相互转换。首先,论文简要介绍了YUV420与RGB24视频图像格式及其相关;其次,以VC++为工具,以个人笔记本电脑为平台,实现了单帧YV420与RGB24视频图像格式之间的相互转换,并且给出、分析了部分用程序代码;最后,认为YUV420与RGB24视频图像格式之间的相互转换对视频会议系统及其技术的发展和创新具有重要的实际工程意义。The color space where each kind of color can be showed by a point is a three-dimensional coordinate system. RGB color space is different from YUV color space, and we can implement the mutual conversion between them. Firstly, it introduced the video image format of YUV420 and RGB24 and their related information briefly. Secondly, it used VC＋＋ to implement the conversion of video image format between YUV420 and RGB24 which are single frame at the platform of personal notebook computer, and gave a part of program code with introductions. Finally, it draws a conclusion that the conversion of video image format between YUV420 and RGB24 has important practical significance to the development and innovation of video-conference system and its technology in aspect of engineering application.
