단색 영상장치를 위한 개선된 Flyod-Steinberg 디더링 기법 연구
Study on the Refining the Floyd-Steinberg Dithering For Monochrome Display
초록
This paper has been studied a method that effectively displaying color image to monochromatic display such as PDA and movable-phone. Generally, the Floyd-Steinberg dithering algorithm has been used in this area and its' effectiveness were well known. But it shows some ugly patterns in white area and also shows some directionality in vertical and horizontal directions. To reduce those directionality, I suggest the error diffusion direction to be rotated randomly according to the bit value of the current position. This can also mitigate some ugly pattern in white area
