ABSTRACT:
In a signal processing apparatus for processing an image signal, a hue difference between adjoining pixels is detected by a color image edge detector, and an aperture control main gain circuit amplifies a luminance signal using a gain determined on the basis of the hue difference detected by the color image edge detector to enhance an edge pixel of an image.
