ABSTRACT:
A vertical detail enhancer for use in a progressive scan video signal processor is disclosed. An interstitial luminance signal producer produces interstitial luminance signals in response to interlaced luminance signals from a source of such signals. Means modify the interlaced and interstitial luminance signals for enhancing the vertical detail of the displayed image by adding only overshoot to leading edges and only undershoot to trailing edges. Further means sequence the vertical detail enhanced interlaced and interstitial luminance signals to produce a signal representing a progressively scanned image.
