Patent ID: 6980733

Claim:
A method for playback of a moving in which an NTSC format image data obtained as 3:2 pull-down from an image of a movie is displayed as a non-interlaced image on a display, said method comprising: sequentially reading image data from a recording medium, onto which said image data has been recorded after conversion of an NTSC system image into digital data, in units of frames; dividing said read-out image data into even and odd fields for each frame individually; judging whether or not an image of an even field in a currently read-out frame is the said image as that of an image of an even field in an immediately previously read-out frame; making a non-interlaced display of the image at a predetermined first time interval in the case in which said judgement was made that images were not the same; reading image data without making said judgment for a predetermined number of successive frames to be read out including said currently read-out frame when said judgement was that images were the same; forming one frame from an odd field of a currently read-out frame and an even field of the next frame to be read out, so as to reduce the number of frames with respect to each of said predetermined number of successive frames; and making a non-interlaced display of said frames obtained from said predetermined number of successive frames at a predetermined second time interval being different from said first time interval.
