The invention provides an image processing method and apparatus of a conference terminal. The image processing method of a conference terminal includes the steps: calling an XopenDisplay function in a kylin operating system to open an image window of the kylin operating system; acquiring the configuration parameters of the image window of the kylin operating system; calling an XGetImage function in the kylin operating system to acquire the screen images displayed in the image window of the kylin operating system; and finally coding the screen images displayed in the image window, and sending the screen images to other conference terminals. The image processing method of a conference terminal opens the image window of the kylin operating system by calling the XopenDisplay function and the XGetImage function in the kylin operating system, and acquires the screen images displayed in the image window. The image processing method of a conference terminal can realize real-time acquisition of the screen images in the kylin operating system in an original conference television system, thus realizing compatibility between the original conference television system and the kylin operating system.
