1. a dynamic image encoding device, it is characterised in that possess:

  • Block cutting unit, is divided into coded object block by input picture;

    Coding control unit, determine infra-frame prediction parameter, this infra-frame prediction parameter be implement forUse during the intra-prediction process of described coded object block;

    Prediction image generation unit, uses described infra-frame prediction parameter, and it is right for described coding to implementAs the intra-prediction process of block, generate the prognostic chart picture comprising luminance signal and colour difference signal;

    Quantifying unit, to described intra-prediction image and the difference of the input picture of described coded object blockPartial image quantifies, and exports the quantization parameter of described difference image;

    AndCoding unit, encodes generate described quantization parameter and described infra-frame prediction parameterBit stream,Described prediction image generation unit is implemented in the frame for the colour difference signal of described coded object blockPrediction processes,Described coding unit is to the colour difference signal for being selected to be applied to described coded object blockOne information of one of multiple intra-prediction process encodes, the plurality of intra-prediction process bagContaining the colour difference signal employing the infra-frame prediction parameter identical with the luminance signal of described coded object blockIntra-prediction process and employ meansigma methods prediction intra-prediction process.
