    • A video display apparatus is provided wherein even for ones, such as 32 pulldown and 22 pulldown, 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. A liquid crystal display apparatus has a means (14) for converting the frame rate by interpolating a picture, which has been corrected based on an interframe motion vector, between frames of input video signals. When interpolating signals representative of two or three consecutive identical pictures generated in telecine or the like, the liquid crystal display 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 motion vectors having higher precision and less errors. The liquid crystal display apparatus has a repeated-picture determining part (10) and utilizes an interval, during which identical pictures requiring no vector detections consecutively appear, to further improve the precision of motion vectors detected between a picture and an immediately preceding different picture.
    • 提供了一种视频显示装置,其中即使是诸如32下拉和22下拉之类的视频显示装置,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,处理时间是 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。 液晶显示装置具有通过在输入视频信号的帧之间插值已经基于帧间运动矢量校正的图像来转换帧速率的装置(14)。 当内插表示在电视电影等中产生的两个或三个连续的相同图像的信号时,液晶显示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 从而检测具有较高精度和较小误差的运动矢量。 液晶显示装置具有重复图像确定部分(10),并且利用连续显示不需要矢量检测的相同图像的间隔,以进一步提高在图像和紧接在前的不同图像之间检测到的运动矢量的精度。
