摘要 |
In picture encoding that generates prediction pictures from picture information of frames previously encoded and encodes picture information for each area, the encoding efficiency is improved. A plurality of motion vector candidates are stored in advance in a motion vector storage memory ( 107 ). A motion vector selection section ( 109 ) selects a motion vector to be used from the plurality of motion vectors stored in advance in the motion vector storage memory ( 107 ). A prediction picture generation section ( 104 ) generates a prediction picture from a reference picture using the selected motion vector. A differential encoding section ( 103 ) encodes a differential between the picture information of the present area and the prediction picture. A motion vector designation encoding section ( 110 ) encodes information that designates the motion vector selected by the motion vector selection section ( 109 ).
