With the popularity of digital camera, digital image processing is getting more important. Most of photographs are not clear enough because of camera sharking, too close to the object or focus failure. So improve these blurring images are one of the major direction in image processing called “Image Deblur”. The blur process can be formulated as the image takes convolution operation with camera shaking path or focus fail. Most common deconvolve improvements are Richardson-Lucy algorithm and Wiener filter. In this paper, we use the Point Spread Function try to represent the blurring image pixels and find out an optimal parameter pair with Wiener filter to improve the image blur.
