中文摘要：

为改善全彩LED显示屏的显示效果,文章提出了一种色温修正的实现方案。本方案采用FPGA（现场可编程门阵列）来完成系统功能,利用Altera FPGA的DSP Builder（数字信号处理生成器）工具,在FPGA内部实现对视频数据进行色温修正的处理,并采用查找表的方法,将视频信号修正至预设的不同色温。最终可将该系统优化成参数可修改的功能模块,即IP核,使其他用户可以直接调用。

英文摘要：

In order to improve the quality of full color LED display,a scheme of color temperature correction（CTC） is introduced.Altera FPGA is used by its DSP Builder Tool to realize the function of CTC which is mentioned here.Moreover,several different color temperatures can be set at the time of initialization using the method of lookup table.After all,this program will be set as a IP Core so that it can be called directly.
