摘要：A coding method including dividing pixels of a chrominance component of aninput image into blocks having a predetermined size; selecting one among a directcurrent prediction method, a vertical prediction method, a horizontal prediction method,and a hybrid prediction method according to a user's input; generating a prediction valueof each pixel in a current block to be predictively coded, using at least one pixel valueamong pixel values in an upper reference block adjacent to the current block and in aside reference block adjacent to the current block, according to the selected predictionmethod; generating a differential value between the prediction value and a

corresponding real pixel value in the current block; and coding the differential value andinformation on the selected prediction method using a predetermined coding method.
