Abstract
A video signal is separated into a broad area luminance signal having attenuated vertical and horizontal detail components and a composite detail signal having horizontal and vertical detail components in a predetermined ratio. The broad area luminance signal is combined with the composite detail signal in desired proportions to provide continuous control of the picture detail from soft to sharp in all directions of reproduced images.
