图像高速转储方法及实现

本文针对图像采集中的图像高速转储处理提出几种可行的方法，并对这几种方法进行了详细分析，给出了相应的实现思路，最后对这几种方法进行了比较分析。

The Methods of the High Speed Saving for the Astronomical Image

The astronomical image collection should be realtime and high-speed. Three methods including the virtual disk, the Expand Memory and the Extend Memory for doingthis by using a simple image collection equipment such as the video CCD with a single frame image card are introduced and analysed in this paper.The program design for each method is also discussed. Finally, the comparison among those methods is given for discussion of the advantages with each method.
