Abstract:
A method of smoothly displaying field videos in an interlaced display, comprising the steps of:displaying a top field video at a top scan timing; converting the top field video into a bottom field video by transform equations; and displaying the bottom field video at a bottom scan timing; wherein the transform equations are given as follows: L(1)=&agr;Ã—L(2)+(1âˆ’&agr;)Ã—L(1) L(2)=&agr;Ã—L(3)+(1âˆ’&agr;)Ã—L(2) L(3)=&agr;Ã—L(4)+(1âˆ’&agr;)Ã—L(3) L(n)=&agr;Ã—L(n+1)+(1âˆ’&agr;)Ã—L(n) Wherein L(1), L(2), . . . , L(n) each represents a scan line of a top field video, respectively and &agr;Ã—L(2)+(1âˆ’&agr;)Ã—L(1)Ëœ&agr;Ã—L (n+1)+(1âˆ’&agr;)Ã—L(n) each indicates a scan line of a bottom field video, where &agr; is an interpolation weighting value with the range of 0 to 1 (i.e., 0
