MOVING PICTURE PREDICTION METHOD, MOVING PICTURE CODING METHOD AND APPARATUS, AND MOVING PICTURE DECODING METHOD AND APPARATUS

摘要

A MOVING PICTURE PREDICTION METHOD FOR ENABLING A CALCULATION AMOUNT AND A STORAGE CAPACITY TO BE REDUCED IN A PREDICTION ABOUT A MOVING PICTURE BY SCALING PROCESSING IS PROVIDED. A METHOD FOR PREDICTING THE VALUE P OF TIME T FROM THE VALUE P0 OF TIME P0 AND THE VALUE P1 OF TIME P1 INCLUDES A STEP OF JUDGING WHETHER IT IS POSSIBLE TO GENERATE A PREDICTIVE VALUE WITH A PREDETERMINED SIGNIFICANT NUMBER OF BITS BY SCALING USING TIME T0, T1 AND T (STEP S90); A STEP OF PREDICTING THE VALUE P FROM THE VALUES P0AND P1 BY SCALING USING TIME T0, T1 AND T WHEN IT IS POSSIBLE TO GENERATE A PREDICTIVE VALUE WITH THE PREDETERMINED SIGNIFICANT NUMBER OF BITS (STEP S92); AND A STEP OF PREDICTING THE VALUE P FORM THE VALUES P0 AND P1 WITHOUT USING TIME T0, T1 AND T WHEN IT IS IMPOSSIBLE TO GENERATE A PREDICTIVE VALUE WITH THE PREDETERMINED SIGNIFICANT NUMBER OF BITS (STEP S91).
