    摘要： The present invention improves efficiency of coding motion vectors when a current block is coded using a plurality of motion vectors. A motion vector coding unit (117) codes a motion vector inputted from a motion vector detecting unit (108). A motion vector for each current block is coded based on a difference between the motion vector and a predicted vector obtained from motion vectors for previously coded neighboring blocks. The predicted vector is generated by one of the following processing: (A) the motion vectors which refer to the same picture are selected from among the motion vectors for the neighboring blocks so as to generate the predicted vector; (B) the motion vectors for the respective neighboring blocks are ordered in the predetermined order, and the motion vectors of the same order rank are selected from the ordered motion vectors so as to generate the predicted vector; and (C) the predicted vector for the second motion vector of the current block shall be the first motion vector, and if the second motion vector and the first motion vector refer to different pictures, the first motion vector is scaled according to the temporal distance between the pictures so as to generate the predicted vector.

    摘要翻译： 当使用多个运动矢量对当前块进行编码时，本发明提高了对运动矢量的编码效率。 运动矢量编码单元（117）对从运动矢量检测单元（108）输入的运动矢量进行编码。 基于运动矢量和从先前编码的相邻块的运动矢量获得的预测矢量之间的差异来对用于每个当前块的运动矢量进行编码。 预测矢量是通过以下处理之一生成的：（A）从用于相邻块的运动矢量中选择参考相同图片的运动矢量，以便生成预测矢量; （B）以预定顺序对各个相邻块的运动矢量进行排序，并且从排序的运动矢量中选择相同顺序的运动矢量以便生成预测矢量; （C）当前块的第二运动矢量的预测矢量应该是第一运动矢量，并且如果第二运动矢量和第一运动矢量涉及不同图片，则第一运动矢量根据时间距离 以产生预测矢量。
