摘要： A predictive coding method for coding intra of frames is revealed. Firstly, an encoder divides an image frame into a plurality of macroblocks. Then the encoder sets predictive coding models corresponding to these macroblocks according to a ratio. The encoder performs predictive coding for coding each macroblock according to the corresponding predictive coding model so as to get and output a coded image. By the present invention, various predictive coding models are set and applied to code the different macroblocks so as to increase predictive coding efficiency. The intra prediction efficiency and image compression efficiency are improved simultaneously.
