    • A video display apparatus is provided wherein even for ones, such as 32 pull-down and 22 pull-down, in which since the motion range of an original material is wide, there is a high probability of degradation of the precision of detected vectors, the processing time is effectively used to enhance the precision of detected vectors, thereby generating interpolated pictures having higher qualities. The apparatus recalculates, based on motion vectors (Va) used in generating the first interpolated picture, motion vectors for use in the next interpolated picture generation, thereby detecting recalculated motion vectors having higher precision and less errors than the original motion vectors. A repeated-picture determining part utilizes an interval, during which identical pictures requiring no vector detections consecutively appear, to further improve the precision of motion vectors.
    • 提供了一种视频显示装置,其中即使对于诸如32下拉和22下拉的视频显示装置,由于原始材料的运动范围宽,因此检测矢量的精度降低的可能性很高, 处理时间有效地用于提高检测矢量的精度,从而产生具有较高质量的内插图像。 该装置基于用于生成第一内插图像的运动矢量(Va)重新计算用于下一个内插图像生成的运动矢量,由此检测具有比原始运动矢量更高的精度和更小误差的重新计算的运动矢量。 重复图像确定部分利用间隔,在该间隔期间连续地出现不需要矢量检测的相同图像,以进一步提高运动矢量的精度。
