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). |

1. A picture decoding apparatus that decodes picture information for an area by generating prediction pictures from picture information of frames that have been previously decoded, the picture decoding apparatus comprising:
a motion vector selection section that selects a motion vector from a plurality of motion vectors that have been stored in advance, where each of the plurality of motion vectors is related to one of a plurality of layers that are provided for scalable encoding; a prediction picture generation section that generates a prediction picture from a reference picture using the motion vector selected by the motion vector selection section; and a decoded picture generation section that generates a decoded picture by decoding a difference between the picture information for the area and the prediction picture. |
