Abstract
An intra-field recursive interpolator reads stored output video from one field store while writing output video into a second field store. The read stored output video is spatially corrected by vertical interpolation prior to being multiplied by a decay constant and being combined with an input video which has been multiplied by the inverse of the decay constant to produce the output video. The resulting output video is a combination of the current input field of video and each preceding field of the output video.
