Abstract:
Apparatus for generating an interpolated line of video, comprising first means for multiplying data from video lines on opposite sides of said interpolated line in a video field by first predetermined coefficients and in response generating a first plurality of product signals, second means for multiplying data from video lines in one or more adjacent video fields by further predetermined coefficients and in response generating a plurality of further product signals, and means for summing said first and further product signals to generate said interpolated line of video which is a weighted average of said data in said video lines of said video field and said one or more adjacent video fields, and wherein said coefficients are chosen such that a first contribution from said video field is greater than a first predetermined value, a further contribution from said one or more adjacent video fields is negative and the total contribution from all video fields sums to said first predetermined value.
