摘要： A video signal processing apparatus for processing a video signal comprises a receive unit (101, 103, 105) which receives the video signal comprising a sequence of pictures. A processing unit (107) applies a picture noise changing algorithm to the sequence of pictures and a variation unit (113) varies a spatial noise reduction setting for the picture noise changing algorithm between at least some consecutive pictures of the sequence of pictures in response to a predetermined variation rule. Specifically a set of picture manipulation processes (203, 205) with different spatial noise reduction characteristics may be provided and the variation unit (113) may select different picture manipulation processes in consecutive pictures. The approach may introduce high frequency noise flickering which is less perceptible to a viewer thereby reducing the perceived noise. The invention may in particular be applied to upconverted high picture rate video signals for hold type displays, such as Liquid Crystal Displays displays.

摘要： A controller for a multi-primary display having M>3 primaries receives a set of input N-primary image color defining values comprising drive values for N primaries for each pixel. A compensator (317) generates a set of compensated N-primary image color (N>=3) defining values by applying a luminance compensation to the values of the set of input N-primary image color defining values where the luminance compensation for each pixel depends on the chromaticity of the pixel. A backlight processor (311) determines backlight levels in response to the compensated N-primary image color defining values. A modifier (313) then generates modified N-primary image color defining values by adjusting the input or the modified N-primary image color defining values or the for the backlight level and a primary converter (315) converts the modified N-primary image color defining values into multi-primary drive values for the display. The approach may e.g. reduce clipping for multi-primary displays with dynamic backlight control by introducing a low complexity pre-processing luminance compensation to existing equipment.

摘要： A device and method for rendering content that includes analyzing previous and/or subsequent temporal portions of a content signal to determine elements that are positionally related to elements of a current portion of the content signal. The current portion of the content signal is rendered on a primary rendering device, such as a television, while the elements that are positionally related to elements of a current portion of the content signal are concurrently rendered on a secondary rendering device. In one embodiment, the elements that are rendered on the secondary rendering device may be rendered at a lower resolution and/or lower frame rate than the rendered current portion of the content signal. In one embodiment, at least one of previous and subsequent temporal portions of a content signal may be analyzed at a lower resolution than the content signal.

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，并且基于感知属性多彩性，其中较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，然后通过将白色仅添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。

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： A method of processing image data comprises receiving input signals for specifying red, green and blue colors of the pixels of a display, performing a per-pixel low pass filtering of the input signals, the low pass filtering function being dependent on the chrominance variation between adjacent pixels, and providing the filtered output signals for use in driving the pixels of a display. This method essentially measures the chrominance variation of the incoming signal, in the form of the color change frequency, and depending on this variation, adaptively low-pass filters the incoming signal. This can be in such a way that the chrominance resolution of the outgoing signal is below the maximum chrominance resolution of the intended display, without errors in the average color of a small group of pixels.

摘要： A method for processing color image data that enables to optimally render a color image on a target device. The method incorporates a color gamut mapping step, where the amount of gamut mapping is adapted dynamically, in dependence of at least a color saturation value of the input pixel. Preferably, also a luminance value of the input pixel is used. The adaptive gamut mapping incorporates correction of saturation, and preferably also hue and white point, of the image data. The color gamut of the target device is used to the fullest possible extent, while clipping and loss of local details in highly saturated areas of the input image is largely prevented.

摘要： The invention relates to a method and a circuit arrangement to reduce motion blur of images shown in non-stroboscopic display devices, in particular Liquid Crystal Display Panels (LCDs). Thin Film Transistor Displays (TFTs), Color Sequential Displays. Plasma Display Panels (PDPs), Digital Micro Mirror Devices or Organic Light-Emitting Diode (OLED) displays, in which motion vectors depending on moving components in each image of an input video, signal are calculated, in which anti-motion blur filtering of the input video signal is performed based on the calculated motion vectors to produce an output video signal, and in which images are generated on said display device depending on said output video signal. In order to provide an improved spatial filtering with less noise enhancement and less noise modulation, it is proposed that edge characteristics in each image of the input video signal are determined and that anti-motion blur filtering is further based on said determined edge characteristics. In this way, spatial filtering is concentrated on significant parts of an image only, and both noise enhancement and noise modulation are reduced.
