According to the embodiment of the present invention, provided is an image error diffusion method for changing, an error diffusion ratio relative to the each pixel of an image. Further, according to another embodiment of the present invention, in order to generate a half tone image that highly correlates with an original image without losing the characteristics of the image, first, the characteristics of the input image are extracted, and then, the obtained results and input/output information are used to adjust, for each pixel, the diffusion state of a quantization error.
