采用子场技术来实现灰度显示的彩色等离子体显示器(PDP),在显示运动图像时出现动态假轮廓现象,增加子场数减少主子场权重,并优化子场排列顺序是一种行之有效的减少动态假轮廓的方法,其缺点是子场数目多。减少子场数目,舍去小权重子场将产生误差,为了补偿由此带来的误差,提出了改进型误差扩散技术,其效果明显优于普通的误差扩散技术,使图像质量大为改善。
The use of sub-field technology to achieve gray-scale display of color plasma display panel (PDP), the dynamic image appears in the dynamic contour phenomenon, increase the number of subfields to reduce the main subfield weight, and to optimize subfield arrangement order is an effective The method of reducing the dynamic false contour has the disadvantage of a large number of subfields. To reduce the number of sub-fields and to discard the small-weight subfield, errors will be generated. In order to compensate for the errors caused by this, an improved error diffusion technique is proposed. Its effect is obviously better than that of ordinary error diffusion techniques, which results in greatly improved image quality.
