Abstract
A method and apparatus for deriving a motion aperture signal that is added to a video signal to cause amplification of the high frequencies of the video signal during movement is disclosed. This method and apparatus operates with an interlaced scan television system by line interpolation of the fields adjacent to a present field of interest. One suggested interpolation means uses delay lines working in conjunction with a summer to vertically align adjacent fields with the field of interest. In order to match the amplitude response of the interpolation means operating on the adjacent fields and the amplitude response of the present field of interest, a filter is disclosed having the same delay line components as the interpolation means.
