摘要
激光显示设备具有宽色域、高饱和度、高亮度的特点,不论是高清电视的709色域信号,还是4K电视的2020色域信号,亦或其他规范的色域信号,在激光显示设备上展现,必须对图像的视频信号进行色域扩展或映射。本文在研究梳理4K电视信号在激光显示设备上展现的色域问题基础上,探讨面向激光显示环境的4K/大色域信号获取方法,以及在信号获取过程中应采用的色彩管理方法。
The laser display device has characteristics of wide color gamut,high saturation and high brightness,whether it is the 709 color gamut signal of HDTV,the 2020 gamut signal of 4K TV,or other standard color gamut signal.The video signal should be gamut expanded or mapped.After studying the color gamut of 4K TV signal on laser display equipment,this paper discusses the method of 4K/wide color gamut signal acquisition for laser display and the method of color management in the process of signal acquisition.
