Line gamut boundary (LGB):the points of intersections between a gamut boundary(as characterized by a GBD) and a given line along which mapping is to be carried out. (不太懂?) Color Gamut: 在一定观看条件下,再现颜色设备(如CRT显示器)上可得到的一系列颜色。在颜色空间上是一个体积如下图 一、...
Gamut mapping is the problem of transforming the colours of image or video content so as to fully exploit the colour palette of the display device where the content will be shown, while preserving the artistic intent of the original content's creator. ...
(SDR_709), characterized in that the reversible gamut mapping comprises applying a respective mapping function (F1, F2, F3) to each of the three R, G, and B color components of the second RGB representation to respectively obtain output R, G, and B color components (Ro, Go, Bo) which...
Combined with the preceding chroma-dependent lightness compression, this helps preserve the saturation because shear mapping using the reference points sometimes causes the source point to over-compress in chroma (see Figure 16). Figure 16: Shear mapping, lightness compression toward hue reference J, ...
-f function f = forward*, b = backwards -i intent p = perceptual, r = relative colorimetric, s = saturation, a = absolute (default), d = profile default -o order n = normal (priority: lut > matrix > monochrome) r = reverse (priority: monochrome > matrix > lut) ...
We have obtained the color gamut transformation matrix which transfers the former CCFL BLU LCD display gamut system to our RGB LED BLU LCD display gamut system and we have also extended color saturation by suppositional color expansion method. As a result, the 32 in RGB LED LCD display ...
The dots are colored using an RGB matrix based on primaries at the very corners of the xy chromaticity diagram, a slightly larger space than Wide Gamut RGB. This minimizes the artifacts seen when using smaller RGB spaces; there is still a hint of a streak running from the blue corner to...
adding extended-gamut color space support, defining additional aspect ratio indicators, defining two additional types of supplemental enhancement information (post-filter hint and tone mapping), and deprecating one of the prior FRExt profiles that industry feedback indicated should have been designed diff...
In an example, a method of gamut mapping may include generating a first second-order or higher response-surface regression model that maps color values corresponding to the second c
The embodiments disclosed herein comprise a plurality of modules and means to provide effect dynamic gamut mapping and backlight control. In one embodiment, a display system compris
