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 to obtain corresponding coefficients associated with each of the horizontal and vertical directions; obtaining weights corresponding to each horizontal and vertical direction, wherein the weights are calculated by applying the coefficients to predetermined weight calculation equations; and restoring the image segment by applying the detected weights to one of an iterative form and a closed form of an image restoration.
