SIGNAL RPOCESSING METHOD AND APPARATUS FOR SAMPLED COLOR IMAGE SIGNAL |
摘要 |
Signal processing method and apparatus are proposed for processing a sampled color image signal of the type having a highly sampled luminance component G and less highly sampled chrominance components R and B to produce interpolated chrominance component values between sampled chrominance component values. The method comprises the steps of producing hue component values at neighboring chrominance component sample locations as a function of a luminance value and the chrominance value at the neighboring locations; producing a signal representing an interpolated hue component value as a function of neighboring hue component values; and producing a signal representing an interpolated chrominance component value as a function of the interpolated hue component value and a luminance value at the interpolated location. The signal processing method reduces color fringing in an image reproduced from the sampled image signal wihtout introducing unwanted hue shifts. |
