摘　　要：为实现数字图像的实时处理,在FPGA上应用硬件描述语言实现功能模块的方法,利用FPGA技术,在数码摄影系统前端对Bayer格式图像进行实时彩色复原,并对系统进行调试.选用四合一简单算法处理Bayer图像,使其恢复成全彩色图像,并用MATLAB软件先验证算法的正确性与可靠性,最后在ISE上进行工程仿真.仿真实验表明,系统工作实时、正确、可靠.In order to achieve the real-time processing of digital image,hardware description language is applied to realize FPGA functional modules. Then,FPGA technology is utilized. Real-time color image restoration is done for Bayer pattern image at the front end of the digital photography system. And finally,the system is debugged. This paper chooses a four in one simple algorithm to process Bayer image in order to restore the perfect color images. Then,MATLAB software is used to test the validity and reliability of the algorithm. Finally,engineering simulation is done on ISE. The method used is simple,and has strong operability. Experiments show that the system works in a real-time,accurate and reliable way.
