摘要

This invention calculates the rate of occurrence of combination of the optimum forecasting mode which is chosen concerning the block which corresponds with the significant layer and the low order layer three-dimensional on the basis of the optimum forecasting mode which is chosen with former encoding at the time of scalable dynamic picture image encoding, generates the corresponding table which describes concerning those relations. Consequently, combination of the optimum forecasting mode which is described to the corresponding table on the basis of rate of occurrence is squeezed, information of the forecasting mode correspondence which is described that concerning the combination of the optimum forecasting mode which is squeezed is generated. And, when block of the significant layer is encoded, by the fact that you access the information of forecasting mode correspondence with the optimum forecasting mode which is chosen with encoding the block to which the low order layer corresponds three-dimensional as a key, deciding the forecasting mode search candidacy which is searched with that encoding, try to decrease the quantity of forecasting mode search candidacy.
