Abstract:
1. A predictive coding method for coding texture of images comprising the steps of: dividing an image frame into a plurality of macroblock by an encoder and the image frame corresponding to at least one texture; setting the macroblocks as a plurality of first macroblocks and a plurality of second macroblocks by the encoder according to a ratio between a fast intra-prediction mode and a full search mode; a setting information is generated; the first macroblocks are corresponding to the fast intra-prediction mode while the second macroblocks are corresponding to the full search mod; the setting information representing distribution of the first macroblocks and the second macroblocks; and detecting and using the fast intra-prediction mode or the full search mode for predictive coding of the first macroblocks and the second macroblocks by the encoder according to the setting information; wherein when the encoder uses the fast intra-prediction mode for predictive coding of the first macroblocks, predictive coding is performed in accordance with neighboring macroblocks of the first macroblocks by the encoder; when the encoder uses the full search mode for predictive coding of the second macroblocks, predictive coding is performed in accordance with different prediction modes for the second macroblocks by the encoder.
