摘要:
The present invention provides an image display apparatus capable of reducing a judder and simultaneously weakening the degree of reducing the judder at the time of converting frame rate of a film signal using motion compensation. At the time of converting frame rate of a video signal by adding N (N: integer of 2 or larger) interpolation frames into between original frames neighboring each other along time base obtained from video images in original frames by using motion compensation so that interpolation positions of the video images in the N interpolation frames are set to a deviated position which is closer to the nearest video image in the original frames rather than positions obtained by equally dividing, into (N+1) portions, magnitude of video image motion between an earlier original frame and a following original frame along the time base.
