在现有的图像缩放技术中，越来越多地采用了非线性滤波器进行图像的插值操作。采用非线性滤波器虽然能得到较好的图像效果．但存在的问题是其引起的振铃现象相对于传统方法更加明显。针对非线性滤波器的上述缺点设计了一种去振铃的算法，并在此算法的基础上给出了硬件的实现，通过了FPGA的验证调试？结果表明，在使用较少硬件资源和最大限度地保留原图像细节信息的基础上，图像缩放后的振铃现象得到大幅度的改善.

More and more non-linear filters for image interpolation are used in the existing image scaling technology. As we know, non-linear filter can get a better image quality, however, the ringing phenomenon caused by the method becomes more serious than traditional ones. In this paper, a deringing algorithm for the shortcomings of non-linear filters is brought forward, at the same time the hardware implementation based on this algorithm has been achieved and verified by FPGA. The result shows that the ringing phenomenon in the image scaling has been improved greatly with Jess hardware resources and maximizing the retention of the original image details.
