Abstract
When extraction start and end compressed pictures are specified from compressed moving picture data of MPEG (Moving Picture Experts Group) standard, a picture block is fixed which has compressed pictures arranged in the order of displaying with those start and end pictures selected for the opposite ends of the block. If the bidirectional prediction or previous prediction compressed pictures within the picture block have a picture to be required to expand by referring to an outside intraframe compressed picture and/or a previous prediction compressed picture that are out of the picture block, the outside prediction picture to be used for the expansion is added to the compressed pictures within the picture block to produce the range of data being edited. That is, at the time of editing the range of the picture block is changed so that the reference to outside data can be completed within the picture block in a closed manner.
