| description | A method and apparatus for multi-level color error diffusion employs semi- vector quantization. When operating on image data comprising three color separations, the method employs a vector quantization for the two separation s with the most visually perceptive color output to generate a multi-level output pixel for each separation based on the sum and a difference of the input pix el values for the two separations. The method generates multilevel output pixel s for the third color separation using scalar error diffusion. |
