摘要
宽色域技术是目前画质增强方向的研究热点之一,该技术可以大大提高视频图像的色彩还原能力,改善人眼的视觉感受.扩展色域的方法主要分为3个方向,传输"负"值色光、高饱和三原色以及多原色.首先简述了宽色域技术的研究意义,然后主要对现有标准色域和主流宽色域标准进行了介绍,并且详细阐述了多原色宽色域的成像与显示技术,最后讨论了该领域待解决的问题以及未来发展趋势.
Abstract
Wide color gamut technology is one of the hot topics in the direction of image quality enhancement,which can considerably improve the color reproduction ability of video images and improve the visual perception of the human's eyes.The method of expanding the color gamut is divided into three main directions,the transmission of"negative"color light,high-saturation three-primary colors,and multi-primary colors.First,the research significance of wide color gamut technology is briefly described,then the existing standard color gamut and normal wide color gamut standards are introduced,and the imaging and display technology of multi-primary-color wide color gamut is elaborated.Finally,the problems to be solved in this field and the future development trend are discussed.
