Abstract: Image blur is difficult to avoid in many situations and can often ruin a photograph. Thus Image deblurring and restoration is necessary in digital image processing. Blur is a form of bandwidth reduction of an ideal image owing to the imperfect image formation process. This is due to the fact that there is a lot of interference in the environment as well as movement during the image capture process, by the camera or, the when long exposure times are used, by the subject, Out-of-focus optics, use of a wide-angle lens, atmospheric turbulence, or a short exposure time, which reduces the number of photons captured and scattered light distortion in confocal microscopy.  This work seeks to reduce the possibility of taking blurry images by developing a Wiener filter algorithm for image deblurring process using MATLAB
