Abstract
In terms of the transmission of the coding method, it is ensured to decode information coded according to the intra-frame prediction coding with vector information. An error of a piece of divisional image information targeted for image prediction coding and a piece of predicted information is determined to perform prediction coding. A data stream in which a piece of information for identifying a prediction method and a piece of information subjected to prediction coding according to the method are arranged is produced according to the process sequence of the prediction coding for each process on the divisional image information. At this time, the data stream has a pair of vector information and the error information as information subjected to prediction coding for each process on the divisional image information on condition that the prediction method is intra-frame prediction coding with vectors.
