First Claim
Patent Images

1. the video data from the expression sequence of video images makes up the method for video image blocks, comprises step:

  • Determine the zone of the measurable image that the use error correction makes up;

    Selection as the reference image, predictably makes up piece from the selective image of video image;

    Use replaces described zone to make up described video image blocks from the data of described reference picture, and wherein, right to use repeated factor predictability ground makes up video image, calculates weight factor based on described predicted picture, and based on following content conversion weight factor;

    The image of prediction and the ratio of the relative distance between the relative distance between the video image in sequence of video images and reference picture and the video image in sequence of video images.
