包括微显投影机和液晶电视的较新显示技术,不受荧光类显示器(如CRT)的色域限制,而能扩展色域覆盖大部分的自然颜色。测算和比较这些扩展色是困难的,而且显示业界没有标准方法可使用。在这个系列讨论的第一部分,将会解释与宽色域相关的色度问题,涉及色度、色差表达和视频信号色域的基本问题。 Newer display technologies, including microdisplay projectors and LCD TVs, are not limited by the color gamut of fluorescent displays such as CRTs, but extend the color gamut to cover most of the natural color. Calculating and comparing these extended colors is difficult and shows that there is no standard way in the industry to use them. In the first part of this series of discussions, we will explain the chromaticity problems associated with the wide color gamut, the basic issues relating to the chromaticity, color difference expression, and color gamut of the video signal.
