Abstract
In the motion prediction processor outputting the encoding type designating the inter-frame or intra-frame prediction coding and the motion vector in case of performing the inter-frame prediction coding, the coordinate values of the currently processed block are outputted and an offset is supplied to the address for reading out the reference region from the reference frame memory. The evaluation data for estimating the coding quantity in case of performing the inter-frame prediction coding is also outputted. An n number of the motion prediction processors are arranged and respectively associated with reference frame memories. The reference regions different from the same block are supplied to the n motion prediction processors and the motion prediction processor with the least evaluation data is selected from among the motion prediction processors whose reference regions are comprised within the picture. The motion vector outputted by the thus selected processor is corrected and outputted.
