Bayer格式图像压缩方法及FPGA实现

单片CCD或CMOS传感器数字相机采用CFA获得彩色图像信息。在分析Bayer格式图像特殊性的基础上，讨论了Bayer图像的几种压缩方法，提出了用色度空间和频域误差等多种方法评价压缩算法性能的方法，这些方法较全面地反映了算法的性能差异并为合理选择提供了依据。最后，提出了一种算法的FPGA实现方案，经验证其性能满足设计要求。

Compression Methods and FPGA Implementation for Bayer Pattern Image

Digital still camera using single-chip CCD or CMOS sensor acquire colorful image with a Color Filter Array(CFA). Based on the analysis of particularity of Bayer pattern, some methods and issues were discussed involving the compression of CFA data before compression. Then, a new chromaticity space measure method and CZP measure method of image quality are proposed. These methods can highly reflect the differences between performances of the methods and give guidance for selection. Last, a pre-process method is simulated and tested by hardware of FPGA with a simulation wave show.
