摘要： A multi-primary conversion (5) of input drive values (RGB) defines a color of a pixel (PI) of a multi-primary display(DP) in an M dimensional color space (XYZ) into N > M output drive values (di) in an N dimensional drive space. The N output drive values (di) drive N sub-pixels (SPi) of the pixel (PI). The color of the pixel (PI) in the color space (XYZ) is defined by linear combinations of N color primaries of the respective N sub-pixels (SPi). The multi-primary conversion(5) comprises: defining a constraint in the color space (XYZ) thereby causing in the color space (XYZ) a convex polytope (U0; L0; V50) defined by vertex points (V10, V11, V12; V20, V21; V50), wherein only colors in the color space (XYZ) belonging to the convex polytope fulfill the constraint, determining exemplary solutions of the output drive values (di) for at least a subset of the vertex points (V10, V11, V12; V20, V21; V50), and constructing the output drive values (di) fulfilling the constraint as a convex combination of the exemplary solutions.

摘要： A display control apparatus comprises a video source(105) which provides a video signal comprising frames. The video source (105) is coupled to a compensation processor (107) which filters at least part of a first frame to provide a compensation for perceived motion blur. A display output (109) feeds the compensated video signal to a display (103) which presents the frame. A controller (111) is arranged to control the display (103) such that it radiates light in a sequence of light pulses for each frame where the sequence of light pulses comprising at least some light pulses having different durations. A motion blur processor (113) determines a suitable compensation filter for the perceived motion blur compensation as one that corresponds to an inverse filter of the sequence of light pulses. The use of pulsed light radiation modifies the hold effect filtering such that it can be better and more easily compensated by pre-filtering.

摘要： An apparatus and method for primary color correction and clipping is provided that is particularly suited for application in mobile displays. It is a combination of a brightness reduction, and a `smart' clipping algorithm and is based on the perceptual attribute "colorfulness", in which images that are brighter seem to posses more color. In the smart clipping algorithm, a brightness reduction is followed by a gamut (primary) correction and then a smart clip is performed by "adding white" to the out-of-gamut pixels only. This reduces the saturation while it increases the brightness. That is, the saturation is decreased in favor of increased brightness, which gives similar colorfulness on a mobile display as on an EBU display. This smart clipping affects those colors that cannot be represented on the display.
摘要翻译：提供了一种用于原色校正和限幅的装置和方法，其特别适合于在移动显示器中的应用。它是亮度降低和“智能”裁剪算法的组合，并且基于感知属性“色彩”，其中更亮的图像似乎具有更多的颜色。在智能裁剪算法中，亮度降低之后是色域（主）校正，然后通过将“白”附加到色域外的像素来执行智能剪辑。这会降低饱和度，同时增加亮度。也就是说，饱和度降低，有利于增加亮度，这在像EBU显示器上一样在移动显示器上产生类似的色彩。这种智能剪辑会影响显示屏上无法表示的颜色。
