Because of the limitations of cost and size of the navigation photo-electricity equipments

we need to get images and videos as clear as possible without changing the structure of navigation photo-electricity equipments. Thus

this paper introduces a method based on DSP image processing system to realize super-resolution reconstruction which realizes motion estimation by the united optimized algorithm of Fourier-Mellin and Keren firstly

and achieves super-resolution image reconstruction based on projection onto convex sets

lastly realizes the method on DSP by optimizes the method based on the feature of DM642 without reducing the accuracy .This method improves the resolving power of the image system without increasing the size of system structure as well as enhance the identify ability of the system. Experiment results indicate that the detail of reconstruction image is clearer than that of the single frame interpolation image

and the average gradient and the information entropy also get improved.
