摘　　要：针对图像在打印传输或者扫描过程中,存在大量误差,图像发生失真。该文提出一种专门应用于图像的交织里德所罗门码设计方法,该方法是通过用交织编码将图像中突发错误离散为随机错误,再由RS(里德所罗门码)编码处理随机错误。两种方法的结合作用,最大限度地提高数据纠错能力,利用C语言程序实现。试验结果证明,图像交织里德所罗门码法很好地纠正了图像中错误数据,使图像质量大幅提高,效果明显。This paper proposed a special design applied to images to solve the problems of huge errors and distortion of images in the process of print and scan, which was called Interleave Reed-Solomon Code Design of Images. The method combined the inter- leave coding with RS coding to improve the ability of data correction.The C language realizes the method.The interleave coding can turn the unexpected error to the random error , the RS coding can correct the random error. The experimentation results showes that the method can correct the error data of the images and avoids improve the quality of the damaged images and have a very obvious effect on images.
