The invention discloses a motion blurred image restoration method based on rich marginal region extraction. Firstly the high frequency layer information of a motion blurred image is acquired, and then the rich marginal index is calculated in a sliding window mode to extract the rich marginal region so that a local region substituting the whole image is acquired; and then the blurring kernel is estimated according to the extracted rich marginal region, and the whole motion blurred image is restored by using a restoration algorithm on the basis of the obtained blurring kernel. According to the motion blurred image restoration method based on rich marginal region extraction, the motion blurred image is restored so that the image restoration time can be reduced and the image restoration effect can be guaranteed in comparison with the present restoration method, and efficient restoration of the motion blurred image can be realized.
