Graduation adjustment of a binary image is different from the grayscale image. Printing density measured value of binary image dots is regarded as the gray value of a grayscale image. In this study, based on the boundary pixel conversion around a dot, we propose the graduation adjustment scheme for image shading information. The scheme shows the effect of suppressing image blurring and folding noise.
