【摘要】 目前嵌入式系统特别是PDA的屏幕越来越大,已经达到了VGA分辨率,但是多媒体和游戏程序在如此高的分辨率下的性能并不尽如人意。本文提出了一种先渲染在低分辨率下,再放大来提高程序速度的方法,并提出一种快速优质的图像放大算法,最后应用到实际程序中,并给出测试结果。更多还原

【Abstract】 The screens of embedded systems, especially those of PDAs are growing larger and larger, even to the VGA resolution. But many multimedia and game programs do not work so well at such high resolutions. This paper provides an effective solution to speed up programs by rendering at low resolution before magnifying to the proper size. A fast and efficient image magnification algorithm is provided in the paper and applied to optimize a real- world program. Testing results are listed at the end.更多还原
