A coding parameter set conversion section first sets the coding structure for a pair of upper and lower macro blocks based on the coding structures of the corresponding macro blocks and converts the remaining parameters such as a motion vector based on the coding structure. A coding parameter set generation section generates coding parameters of an intraframe coding parameter, etc., a coding parameter set selection section selects an optimum parameter set, and a coding section performs recoding processing.
