Because the real-time process capability and cost performance of the universal computer are not high when used to remove image rotation,this paper researches and designs a real-time removing image rotation system,using C6455 DSP chip as the core processor.The system can realize a series of functions,including image sampling,removing rotation and image transfer.The experiment results show that this system has good real-time processing ability and the images processed is of high quality.It has been applied to a practical system to remove image rotation.
