摘要: 简要介绍了Windows系统中GDI,DrawDib函数集、DirectDraw 3种图像显示技术的特点,介绍了视频图 像缩放的理论和实现方法,研究对比了Windows系统中支持的几种图像显示技术的执行效率,并对其放大效果 与软件插值算法进行了比较,最后给出了实验结论。Abstract: The features of three video technologies for Windows system,i. e., GDI, DrawDib function set and DirectDraw, are briefly introduced. The theory and implementation methods of image zoom through sampling rate conversion are also introduced. The executive efficiencies of the three video technologies are compared, and the effect of the up-conversion images produced by these technologies for Windows is compared to that by software interpolation algorithm. And some experimental conclusions are presented
