The Research of Bayer Format Color Image Recovery System Based on FPGA

In front of digital cameras system, to Bayer format image real-time color restoration with the rapid development of FPGA techniques.Comparison of several interpolation algorithm and PSNR for selecting the best interpolation algorithm.The improved Bayer interpolation algorithm was only used addition and shift algorithm in the system,so the hardware realization is very easy and improves the system real-time.FPGA as the master control chip,has the advantages of simple structure and programmable,so that the whole system has great flexibility.
