Therefore, by predicting values of pixels positioned at each directional edge, among pixels constructing a 2×2 block in a current image, using values of neighbor pixels of the pixels positioned at each directional edge, selecting an edge mode corresponding to a directional edge in which the difference between the predicted values and actual values of the pixels is a minimum, and outputting edge mode data indicating the edge mode instead of the predicted values corresponding to the edge mode, it is possible to effectively compress edge areas in which little similarity exists between pixel values, and accordingly improve a compression rate of edge areas.

摘要： A method, medium, and system effectively compressing and/or restoring binary images. By compressing pixel values making up a 2×2 block in an input image, using representative values representing the pixel values and a pattern of the pixel values represented by the representative values, it is possible to effectively compress and/or restore binary images having little similarities between pixel values.
