「立體色域」是奇美發明的中文名稱。其重點是與工研院合作的「快速色域量測技術」。

各家廠商其實都是在講相同的東西。
只是最設計出來給消費者使用的「控制/調整功能」有著不同程度的差異性。
基本的定義有這些:
Hue
The "attribute of a visual sensation according to which an area appears to be similar to one of the perceived colors: red, yellow, green, and blue, or to a combination of two of them".
Intensity, radiance
The total amount of light passing through a particular area.
Luminance (Y)
The radiance weighted by the effect of each wavelength on a typical human observer, measured in candela per square metre (cd/m2). Often the term luminance is used for the relative luminance, Y/Yn, where Yn is the luminance of the reference white point.
Luma (Y′)
The weighted sum of gamma-corrected R′, G′, and B′ values, and used in Y′CbCr, for JPEG compression and video transmission.
Brightness
The "attribute of a visual sensation according to which an area appears to emit more or less light".
Lightness, value
The "brightness relative to the brightness of a similarly illuminated white".
Colorfulness
The "attribute of a visual sensation according to which the perceived color of an area appears to be more or less chromatic".
Chroma
The "colorfulness relative to the brightness of a similarly illuminated white".
Saturation
The "colorfulness of a stimulus relative to its own brightness".

其他參考資料如下(均引用自WIKI),有興趣可自行研究:
1. RGB 色彩空間
基本的7種顏色:R、G、B、C、M、Y、W。
有大大曾提到,電視機的每一顏色的色彩顯示,都是以白色為基礎再進行混色而成。
所以白色(灰階)在電視機上就變的非常重要。
2. HSL和HSV色彩空間
3. HSV色彩屬性模式
4. Rec. 709
這個是HDTV色域規範的圖示。HDTV廣播與BD影像的製作等,都是採用此色域大小。
