Research Progress of Wide Color Gamut Video Image Technology
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.
