%X In acquiring image, due to the relative motion between an imaging system and its objects, the every value of grey scale of pixels expresses several ones within area instead of itself one pixel. It, thereby, results in imaging degrading, and engenders blurring imaging. The paper analyses a real process about image blurred as a result of object motion, reveals an intrinsical cause about image-degraded owing to object motion, and establishes blurring-model by which one dimension and two dimensions uniform velocity rectilinear motion result in image blurred abide. Based on result of blurring imaging pixel motion, the writers introduce a restoring model of blurring imaging from reverse process of degrading-process and conclude a restoring technique of motion blurring imaging from it. As an instance, the paper models a blurring process for uniform velocity rectilinear motion and restores it again. The example conforms the technique is available, especially for restoring characters and texts. A special discuss on boundary pixel problem is given. An analyse about error cause in process of restoring is introduced. In the end, the method's advantage and disadvantage and how to improve on it were discussed.
