目前各类非高依赖DirectDraw应用中屏幕捕捉技术存在效率低下、捕捉遗漏、光标丢失以及不够稳定等问题。为此，提出基于镜像显示驱动的屏幕图像捕捉方案。设计并实现内核驱动，通过捕捉鼠标光标移动路径中的关键点再现光标轨迹，并对捕获到的变化区域集进行优化合并。实验结果证明，该方案能快速稳定地捕捉屏幕上的变化区域图像，实现光标的移动捕捉。

In order to resolve the low efficiency issue, capturing-omitting and mouse cursor-missing problems in screen image capture technology for applications with non-high-dependency of the DirectDraw, this paper realizes Mirror Driver, redraws the track of cursor by capturing key points in moving-path and combines the updated regions grabbed to optimize the performance. Experimental results show that the resolution is speed-fast and stable when capturing the modified areas including mouse cursor-moving path on desktop.
