1. dynamic image encoding device is characterized in that possessing:

  • The coding control unit, decision becomes the full-size of encoding block of the processing unit of prediction processing, and determine the hierachy number of the upper limit when maximum sized encoding block is cut apart by level ground, from available coding mode more than 1, select and each encoding block corresponding codes pattern of being cut apart by level ground;

    The piece cutting unit is divided into the maximum sized encoding block that is determined by described coding control unit with input picture, and until the hierachy number that arrives the upper limit that is determined by described coding control unit, cuts apart to level described encoding block;

    The predicted picture generation unit to the encoding block that is partitioned into by described cutting unit, is implemented the prediction processing corresponding with the coding mode of being selected by described coding control unit, thus the generation forecast image;

    The difference image generation unit generates the encoding block cut apart by described cutting unit and the difference image of the predicted picture that generated by described predicted picture generation unit;

    Image compression unit is compressed the difference image that is generated by described difference image generation unit, exports the packed data of described difference image;

    AndThe Variable Length Code unit, to carrying out Variable Length Code from the packed data of described image compression unit output and the coding mode of being selected by described coding control unit, the bit stream of the coded data that has generated described packed data and described coding mode multiplexing,Described Variable Length Code unit is except packed data and coding mode, also the frame intra-prediction parameter of using to by described predicted picture generation unit generation forecast image the time is carried out Variable Length Code, be multiplexed under the situation of described bit stream in the coded data with described frame intra-prediction parameter, frame intra-prediction parameter in the segmentation that expression is partitioned into by described cutting unit whether with the segmentation of described segmentation adjacency in the identical inner sign that merges of frame of frame intra-prediction parameter carry out Variable Length Code, if and described frame intra-prediction parameter is identical, then Variable Length Code is carried out in the inner orientation that merges of frame of the segmentation of determining described adjacency, if described frame intra-prediction parameter difference is then carried out Variable Length Code to the frame intra-prediction parameter in the segmentation that is partitioned into by described cutting unit.
