摘要： A method and apparatus for reduced complexity video and image processing with special chroma handling are disclosed. Frame-type decisions are made on a video stream made up of a sequence of frames. A first subset of the frames are selected to be monochrome and generated without chroma data. A second subset of the frames are selected to be in color and generated with chroma components. In one embodiment, the first subset of frames includes odd frames and the second subset of frames includes even frames in the video stream. Under higher video frame rates, the lack of color in every other frame is not visible to the end viewer. Accordingly, subsequent processing of the output video stream permits luma-only processing of many frames in the video stream, extensively reducing the amount of computation.
摘要翻译：公开了一种用于降低复杂度的具有特殊色度处理的视频和图像处理的方法和装置。在由一系列帧组成的视频流上进行帧型决定。帧的第一子集被选择为单色并且没有色度数据生成。帧的第二子集被选择为彩色并由色度分量生成。在一个实施例中，帧的第一子集包括奇数帧，并且帧的第二子集包括视频流中的偶数帧。在更高的视频帧速率下，每个其他帧中缺少颜色对于终端观看者是不可见的。因此，输出视频流的后续处理允许视频流中许多帧的仅亮度处理，从而大大减少了计算量。

摘要： A liquid crystal display device includes a liquid crystal display panel having a pixel defined by at least three sub-pixels including a blue sub-pixel, a backlight which emits, toward the liquid crystal display panel, light that brings a color temperature to a predetermined level when the pixel displays white, and a color tone correction circuit which corrects a color tone of a color displayed by the pixel. When the pixel displays a color containing at least one predetermined color component that is other than a white component and a blue component, the color tone correction circuit performs a correction to set a luminance of the blue sub-pixel lower than an original luminance.

摘要： Aspects of the invention provide a color matching profile generating device that, in an apparatus having an input device and an output device, performs a color matching for the input device and the output device and reproduces favorable colors without depending on color characteristics of the devices. The color matching profile generating device can use an input device profile and an output device profile, in addition to a color conversion profile which defines color conversion characteristics in an absolute color space and generates a color matching profile for the input device and the output device. Since the color conversion profile defines the color conversion characteristics in the absolute color space, color conversion can be performed to image data obtained from the input device without depending on characteristics of the input device. Accordingly, by performing a color matching process with the generated color conversion profile, image data can be output with color characteristics determined in the absolute color space, irregardless of characteristics of the output device.
摘要翻译：本发明的方面提供了一种颜色匹配简档生成装置，在具有输入装置和输出装置的装置中，对输入装置和输出装置进行颜色匹配并再现有利的颜色，而不依赖于装置的颜色特性。除了在绝对颜色空间中定义颜色转换特性的颜色转换曲线，并且为输入装置和输出装置生成颜色匹配曲线，颜色匹配轮廓生成装置可以使用输入装置轮廓和输出装置轮廓。由于颜色转换轮廓限定了绝对颜色空间中的颜色转换特性，因此可以进行颜色转换，而不依赖于输入装置的特性来从输入装置获得的图像数据。因此，通过利用所生成的颜色转换曲线进行色彩匹配处理，可以输出具有在绝对色彩空间中确定的颜色特性的图像数据，无论输出装置的特性如何。

摘要： An object of the present invention is to provide an image display technology with which high contrast can be stably obtained. In order to achieve the above object, the present invention changes the gain of a digital luminance signal by feeding back information on maximum and average luminance levels of the luminance signal, adjusts image contrast, and in accordance with the average luminance level detected from the feedback system, controls the illuminance of the backlight applied to a display unit. The control increases the illuminance of the backlight when the detected average luminance level is higher than the upper-limit value of a previously set reference range, and reduces the illuminance when the detected average luminance level is lower than the lower-limit value of the reference range.
