%X Firstly, this paper has briefly introduced the images degenera ted model, elements and image restoration method. Secondly, it has improved the local maximum entropy algorithm by applying the statistic property and the chara cteristics of different type image region. Experiment has proved that the algori thm has independence with degeneration model and the size of local image region. It can keep the image details as well as improve the balance of gray and the co ntrast of image. The algorithm has a small computing cost and flexibility.
