Video Halftoning Preserving Temporal Consistency

Video halftoning is a key technology for use in the new display device, electronic paper (e-paper). This is still a rather unexplored field. The challenging issue of video halftoning is the elimination of flicker flaw that will appear due to error diffusion in the temporal domain. In this paper, we propose a new video halftoning method, which is composed of spatial error diffusion and inter-frame reference error diffusion. In addition, since our method can efficiently reduce the flicker flaws, another advantage is that the halftone video sequence can be efficiently compressed. When compared with traditional 2D and 3D error diffusion techniques, experimental results show that our method can significantly reduce the average flicker rates.
