摘要： 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.
