Abstract

Dithering technologies for digital halftoning originate from Roberts' modulation by pseudo-noise. At present, Roberts modulation is not used because of its randomness. However, blue noise dithering methods are now being paid attention to the fastness of algorithms and error diffusion-like image qualities. In this paper, the visual noises and the gray scale reproducibilities by dithering are analyzed back to the Roberts and an improved pseudo-noise is discussed.
