    • The invention relates to an image processor configured to: receive an image, take area-specific samples (11) of the image information of the area and calculate (12) a reference value (REF) on the basis of the samples; store into a memory (16) or to transmit (17) the reference value (REF) calculated for an area and the area identifier (ALUE) area-specifically; check (13) whether the reference value (REF) obtained as a result of the calculation and the image information (INF) corresponding to it have already been stored in the memory (16) or transmitted (15); and to store into the memory (16) or to transmit (15) the calculated reference value (REF) and the corresponding image information (INF), if the reference value (REF) and the corresponding image information (INF) have not been stored into the memory or transmitted previously.

    • Provided are a method and apparatus for encoding an image by dividing a prediction block of a current block into a plurality of regions, thereby compensating for average values of pixel values in the prediction block by each of the plurality of the regions, and a method and apparatus for decoding the image. The method of encoding an image includes determining a first prediction block of a current block to be encoded, dividing the determined first prediction block into a plurality of regions, dividing the current block into a plurality of regions by the same number as in the divided first prediction block and calculating a difference value between an average value of pixels of each region of the first prediction block and an average value of pixels of each region of the corresponding current block, compensating each region of the divided first prediction block by using the difference value and generating a second prediction block, and encoding a difference value between the second prediction block and the current block.
    • 本发明涉及一种方法和装置,用于通过把当前块的预测块分割为多个区域,从而使得像素值的平均值的补偿块中的编码的图像 由每个所述多个区域的预测,以及用于对图像进行解码的方法和装置。 编码的图像的方法包括:确定当前块的第一预测块被编码,在分割的多个区域中确定的第一预测块,当前块分割为多个区域 由相同的数作为第一预测块分割并计算第一预测块的每个区域的像素的平均值与相应的当前块的每个区域的像素的平均值之间的差值,补偿 使用该差值并产生第二预测块,和编码第二预测块和当前块之间的差值的第一预测块分割的每个区域的。
