This paper proposes a method to display a halftone image with only binary pixels from a gray-leveled image. White pixels are allocated in the gray-levels order after the weights based on Bayer matrix are added to all pixels in a local image area. The additional matrix is composed by the decimal weights to determine the order to allocate white pixels easily even if a local area includes multiple pixels with the same gray-level. The proposed method can display an appropriate halftone image even if a gray-leveled image includes even brightness areas. Through the experiments for evaluating the reproducibility of gray-levels, the smoothness of halftone, the resolution and the texture, the equal or better results were obtained by the proposed method in comparison with the conventional half-toning methods.
