<p>Color image signals, as derived e.g. by interpolating the output from a color filter array (CFA) are arranged in pixels, each pixel having associated detected (10) color information for a first color as well as undetected filled-in (20) color information for at least a second and a third color. The images are thus exposed to false color and zipper effect artifacts, and are subject to processing preferably including the steps of: checking (30) the images for the presence of zipper effect artifacts, and i) if said checking (30) reveals the presence of zipper effect artifacts, applying a zipper effect removal process (50) to said image signals; ii) if said checking (30) fails to reveal the presence of zipper effect artifacts, applying a false color removal process (40) to said image signals. False color and zipper effect artifacts are thus preferably both reduced by adaptively using the zipper effect removal process (50) and the false color removal process (40).</p> |
