In this paper, we propose a new color quantization method for generation of the color-reduced images. The proposed method employs a vector error diffusion VED method and a particle swarm optimization PSO. VED method based on Floyd-Steinberg dithering is used for display of the color-reduced image. Furthermore, a color palette used in VED method is optimized by PSO. PSO generates the effective color palette with evaluating a human visibility of the color-reduced image on the display. The validity and the effectiveness of the proposed method are confirmed by some experiments.
