摘　　要：深入分析了各种色彩插值算法的优缺点,并在此基础上,对Lu算法进行了改进,避免G通道插值的除法运算,简化了R/B通道的插值计算,摒弃了后继的迭代修正,使之适合于FPGA硬件系统的实时实现。仿真结果表明,改进后的算法在不明显降低插值效果的前提下节省了硬件资源,提高了工作频率。The advantage and disadvantage of various interpolation algorithm are summed up.In order to fit in the real-time FPGA hardware system,an improvement for Lu algorithm is made to avoid division operation in Green channel interpolation,and simplify calculation in Red/Blue channel interpolation,then the subsequence process is given up.The simulating results prove that the improvement saves a lot of hardware resource and increases operating frequency without much decrease in the interpolation quality.
