    Abstract: In an example, a method for image processing may include inputting a first pixel value corresponding to a first pixel of an image into a LUT. The LUT may map one or more LUT input values to one or more LUT output values. The first pixel value may correspond to a first LUT input value that maps to a first LUT output value in the LUT. The first pixel may include one or more pixel values. The method may include generating a noise value for the first LUT input value. The method may include generating a first interpolated LUT output value for the first LUT input value based on the noise value. The method may include transforming the image into a transformed image using the first interpolated LUT output value.

    Abstract translation: 在一个示例中，用于图像处理的方法可以包括将对应于图像的第一像素的第一像素值输入到LUT中。 LUT可以将一个或多个LUT输入值映射到一个或多个LUT输出值。 第一像素值可以对应于映射到LUT中的第一LUT输出值的第一LUT输入值。 第一像素可以包括一个或多个像素值。 该方法可以包括产生第一LUT输入值的噪声值。 该方法可以包括基于噪声值产生第一LUT输入值的第一内插LUT输出值。 该方法可以包括使用第一内插LUT输出值将图像变换成变换图像。

    Abstract: Techniques are described in which pixel intensity values of a display of a computing device may be nonlinearly scaled down to reduce the power consumption of the display. The computing device may determine a compressed pixel brightness range for the display. The computing device may determine a set of initial scaled pixel intensity levels based at least in part on the compressed pixel intensity range. The computing device may determine a set of scaled pixel intensity values based at least in part on an estimated power consumption value associated with the set of initial scaled pixel intensity levels. The computing device may scale the pixel brightness of pixels of the display from one of a plurality of pixel intensity levels to a corresponding scaled pixel intensity level of the set of scaled pixel intensity levels.
