Abstract:
1. An image processing apparatus comprising: an element for extracting a luminance signal, a first color-difference signal, and a second color-difference signal from a pixel signal; a luminance contour extraction element for extracting a luminance contour component from said luminance signal; a first contour extraction element for extracting a first contour component from said first color-difference signal; a second contour extraction element for extracting a second contour component from said second color-difference signal; a modulation element for modulating said luminance contour component based on said first contour component, and also modulating said luminance contour component based on said second contour component, thereby generating a modulated contour component; and an enhancing element for contour-enhancing said luminance signal by adding said modulated contour component to said luminance signal.
