PREDICTED REFERENCE INFORMATION GENERATING METHOD, VIDEO ENCODING AND DECODING METHODS, APPARATUSES THEREFOR, PROGRAMS THEREFOR, AND STORAGE MEDIA WHICH STORE THE PROGRAMS

摘要

A temporal or spatial inter-frame predictive encoding method is applied to each divided region. A dynamic image of a region-to-be-processed is generated according to a reference frame of the region-to-be-processed and reference information indicating the prediction object position of the region-to-be-processed in the reference frame so as to process a dynamic image. Here, provided is a method for generating predictive reference information as prediction information on the reference information. The reference data used when processing the already processed adjacent region adjacent to the region-to-be-processed is set as predictive reference information prediction data used for predicting the reference information on the region-to-be-processed. Reference region reference information is generated from at least one reference information used when processing the reference region indicated by the prediction data. This modifies the predictive reference information prediction data and generates the predictive reference information by using the one or more predictive reference information prediction data which have been modified.
