1. An image processing method for removing blur in a screen image, said method comprising: detecting blur in an input image; segmenting the image according to an amount of the detected blur; performing a high pass filtering for each segmented image in a horizontal direction and a vertical direction; obtaining weights corresponding to each horizontal and vertical direction by using corresponding coefficients obtained from said filtering in each direction; and restoring the image segment by applying the detected weights to one of an iterative form and a closed form of an image restoration.
