An image processing method is provided. According to the present method, the formulas of the prediction modes of a 4*4 block in intra frame prediction are expanded and applied to 4*4 blocks or 8*8 blocks in a 16*16 block. The prediction modes of the 4*4 blocks or 8*8 blocks in the 16*16 block are determined within one pass, or the prediction modes of the 8*8 blocks in the 16*16 block are determined within three passes. Accordingly, the operation of determining the prediction mode of each 4*4 block is saved, and the time for processing intra frame prediction of the 4*4 blocks is effectively reduced. Eventually, the efficiency of image processing is improved.
