In recent years, the image processing technology has been used in various fields, such as the detection and monitoring and so on. Because the exposure time of camera is not infinitesimal, there is relative motion between the camera and the object being captured during the short exposing time, it causes the image blurry .The blurred image that we capture is worthless and useless. For dealing with this challenging but imperative issue, in this paper, we restore the blurry image from a single image. We analysize the spectrum of the Fourier transform to estimate the point spread function of the blurred image and restore the image in winner filter. In Wiener filter algorithm, different parameter has different influence on the image, we analysize the influence and how to adjust parameter according to the restored results. Some experiments have also been conducted for validating that winner filter is simple, efficient and has a good influence on restoring.
