摘要： Displays such as televisions, computer monitors, and the like may boost (124) the dynamic range of input image data (121). Dithering (128) may be provided to mitigate artefacts made visible as a result of the boosting. Color correction (124) may be implemented. The color correction may compensate for differences between a color of a backlight and a desired white point.

摘要： Apparatus comprising an input connected to receive an input signal, a lookup table comprising a plurality of input entries and first and second output entries for each input entry. The look up table receives the input signal and returns a lower input entry, an upper input entry, the second output entry for the lower input entry, and the first output entry for the upper input entry. A first subtractor subtracts the lower input entry from the input signal to produce a first difference. A second subtractor subtracts the input signal from the upper input entry to produce a second difference. First and second multipliers multiply the first and second differences by the first output entry for the upper input entry and the second output entry for the lower input entry, respectively, to produce first and second products. An adder adds the first and second products to produce an output signal.

摘要： Apparatus and methods are provided to map out-of-gamut points to in-gamut points. Embodiments transform image data for presentation on a display or medium having a gamut different from that of the image data. Different mapping algorithms may be applied based in part on luminance of the points being mapped. Embodiments apply a reduced dataset representing a gamut boundary. Irregular gamuts may be accommodated

摘要： Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data to a maximum range of the image data. Metadata characterizing the mapping is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced.
摘要翻译：图像数据被编码为以较低位深度格式分布。图像数据具有小于最大范围的范围，并且使用映射来映射到较低位深度格式，使得较低位深度表示的范围与较低位深度表示的最大范围的比率更大比图像数据的范围与图像数据的最大范围的比率。表征映射的元数据与较低位深度表示相关联。元数据可以在下游用于逆转映射，使得更好地再现色调细节。

摘要： In one embodiment the present invention includes a method that adjusts a display device according to a display environment. The method includes sensing the display environment of the display device and generating environment data that corresponds to the display environment. The environment data includes color data. The method further includes adjusting a color appearance model according to the color data, generating a control signal according to the color appearance model having been adjusted, and controlling a backlight of the display device according to the control signal. In this manner, a viewer perceives the images displayed by the display device in the manner intended by the content creator, because the adjustments to the color appearance model compensate for the viewer's physiological response to the display environment.
摘要翻译：在一个实施例中，本发明包括根据显示环境调整显示设备的方法。该方法包括感测显示设备的显示环境并产生对应于显示环境的环境数据。环境数据包括颜色数据。该方法还包括根据颜色数据调整颜色外观模型，根据调整的颜色外观模型生成控制信号，并根据控制信号控制显示装置的背光。以这种方式，观看者以内容创作者预期的方式感知由显示设备显示的图像，因为对颜色外观模型的调整补偿了观众对显示环境的生理响应。
