Abstract
Apparatus for enhancing an image represented by picture signals corresponding to respective color components of successive elements of the image comprises signal generators for generating sharp and unsharp signals from the picture signals. Fringe signal generators derive a plurality of fringe signals by combining the sharp and unsharp signals in a predetermined manner; a correction circuit applies connected in parallel with the fringe signal generators modifying functions to the sharp or unsharp signals or other premodified picture signals to derive modified picture signals; and an adding circuit sums the fringe signals with the modified picture signals to derive a plurality of output signals.
