The paper uses DSP chip of TI′s high-performance Davinci series TMS320DM6437 to build a set of video collection, degradation simulation and real-time video image restoration system. First, image degradation and restoration algorithm is simulated by VC++. Then it′s transplanted from software platform to TMS320DM6437 platform. Finally, The algorithm is optimized in the DSP/BIOS real-time operating system and joins man-machine interaction. The result shows that the system can effectively accomplish video image restoration based on good real-time.
