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.

The method comprises setting a transfer unit in a data processing system which repeatedly performs a process of transmitting data stored in a first memory to a second memory in a predetermined transfer unit, processing the transmitted data stored in the second memory, and transmitting the processed data to the first memory. The method includes computing overhead on the data processing system according to the size of each of a plurality of data units available as the transfer unit; and setting a data unit, which corresponds to a minimum overhead from among the computed overheads, as the transfer unit. Accordingly, it is possible to set an optimum transfer unit according to an environment of a data processing system in order to improve the performance of the data processing system.

    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. In addition, by extracting compressed values and a pattern of pixel values making up a 2×2 block in an image, from compressed data of the 2×2 block, and restoring pixel values using the compressed values and the pattern, it is possible to effectively restore binary images.
