| 摘 要： | 根据相加混色原理,建立了常规色域的三维数学模型,在CIE1976LUV三维色度系统与Pointer物体真实表面色色域作了色度学比较.结果表明,常规HDTV传输系统之所以不能传输或重显全部Pointer色域,并不单纯因为色域范围小,两个色域涵盖的颜色范围有差别也是重要原因.这对需要从三维和颜色覆盖范围方面研究色域问题具有...

| Abstract: | To study color gamut of HDTV system in 3D color space,according to additive color mixture theory,3D mathematical model for coventional color gamut is established,which is compared with the gamut of Pointer real surface colors in CIE 1976LUV system.The results show that the reason why conventional gamut transportation system can't transport or reporo-duce all Pointer color gamut is not only because of the small scope of conventional color gamut but also because of the different coverage area between these tw... |
