ABSTRACT:
A system for generating an interstitial signal for a double scanning non-interlaced (progressive scan) television display is disclosed. When no motion is detected in the neighborhood of the interstitial pixel, a pixel generated from pixels in the adjacent fields to that of said interstitial pixel is supplied at the interstitial pixel for further processing. When motion in a relatively downward direction is detected, then a pixel generated from pixels in lower adjacent lines to, and in the same field as, that of the interstitial pixel is supplied as the interstitial pixel. When motion in a relatively upward direction is detected, then a pixel generated from pixels in upper adjacent lines to, and in the same field as, that of the interstitial pixel is supplied as the interstitial pixel.
