    • A motion estimator for generating an interpolation frame based on current and previous frames is provided. The motion estimator includes: a first candidate motion vector calculating unit which divides the current frame into plural blocks and generates plural first candidate motion vector groups, each group including a first candidate motion vector for each of the blocks calculated based on a previous motion vector previously estimated; a second candidate motion vector calculating unit which calculates plural second candidate motion vectors for each of the blocks, each of the second candidate motion vectors being calculated based on a respective first candidate motion vector included in each of the first candidate motion vector group; and a final motion vector deciding unit which selects a final motion vector for each of the blocks from among the second candidate motion vectors, the interpolation frame being generated based on the final motion vector.
    • 提供了一种用于基于当前帧和先前帧生成内插帧的运动估计器。 运动估计器包括:第一候选运动矢量计算单元,其将当前帧分成多个块并产生多个第一候选运动矢量组,每个组包括基于先前运动矢量之前计算的每个块的第一候选运动矢量 估计 第二候选运动矢量计算单元,其针对每个块计算多个第二候选运动矢量,基于包括在第一候选运动矢量组中的每一个中的相应的第一候选运动矢量来计算每个第二候选运动矢量; 以及最终运动矢量决定单元,其从所述第二候选运动矢量中选择每个块的最终运动矢量,所述内插帧是基于所述最终运动矢量生成的。
