In analyzing a coded result to thereby calculate data distribution corresponding to a characteristic of an input image signal, rather than determining data distribution for all of the pictures, an aggregate of such pictures that have roughly the same coding difficulty is captured as one scene. This scene is prescribed as a video edit unit (VEU), so that, in configuration, the input image signal is subdivided into a plurality of video edit units (VEUs) to thereby set an average target coding rate for each of these video edit units (VEUs), which are entered as coding conditions to thereby determine data distribution for each of the pictures at the time of re-coding. <IMAGE> |
