Abstract: Setting the point spread function (PSF) of motion-blurred images is the key problem in image restoration. For uniform linear motion blurred images, the blurring length and direction determine PSF. The reason and condition of black strips in the spectrum images of motion-blurred images and specified the exact positions of black strips were analyzed. A method to accurately estimate the blurring length of uniform linear motion blurred images was introduced. That the method can get accurate result was proved theoretically and experimentally. Finally, the shortcoming of the method was pointed out.
