Fig. 4 carries out the structural representation of infra-frame prediction for image encoding processing method embodiment two of the present invention, as shown in Figure 4, wherein I3 represents that Block3 is carried out the inter prediction intraframe coding to be handled, and obtains first prediction residual, therefore, this first prediction residual has Intra prediction mode; And P0, P1, P2 represent that respectively inter prediction intraframe coding result with Block3 serves as with reference to Block0, Block1, Blcok2 being carried out between pixel encoding process in the predictive frame, obtain second prediction residual respectively, therefore, second prediction residual does not have Intra prediction mode.
Need to prove that in the present embodiment, employed predictive mode can be previously selected optimum Match pattern, those skilled in the art can adopt prior art to select the optimum Match pattern, repeat no more herein.
Obtain owing to I3 adopts traditional inter prediction intraframe coding to handle, it has the Intra prediction mode that characterizes the direction texture information, and the interior encoding process of predictive frame is obtained between P0, P1 and P2 employing pixel, and there is not Intra prediction mode in it.And MDDT must have Intra prediction mode, therefore, present embodiment can adopt the MDDT conversion to I3, promptly adopt the transformation matrix corresponding that I3 is carried out the MDDT conversion with employed Intraprediction mode in the step 202, and P0, P1 and P2 are adopted the conversion that has nothing to do with the direction texture information, for example dct transform.
