Abstract: The processing of RGB image data can be optimized by performing optimization operations on the image data when it is converted into the YCbCr color space. First, a raw RGB color space is converted into a YCbCr color space, and raw RGB image data is converted into YCbCr image data using the YCbCr color space. For each Y-layer of the YCbCr image data, a 2D LUT is generated. The YCbCr image data is converted into optimized CbCr image data using the 2D LUTs, and optimized YCbCr image data is generated by blending CbCr image data corresponding to multiple Y-layers. The optimized YCbCr image data is converted into sRGB image data, and a tone curve is applied to the sRGB image data to produce optimized sRGB image data.

Abstract: The conversion of RAW data captured by a camera can have artifacts in smoothness of various hues for varying chroma. To optimize smoothness and color accuracy, transform coefficients defining conversion of a standard color model to a target color model are determined. The RAW data is converted to data in a standard color model and the data in the standard color model is converted to data in the target color model using the transform coefficients. The process is repeated for various lightness levels and combined into a look up table to efficiently convert RAW data to data in the target color model for various lightness levels.

Abstract translation: 由相机拍摄的RAW数据的转换可以具有用于变化色度的各种色调的平滑度的伪影。 为了优化平滑度和颜色精度，确定将标准颜色模型的转换定义为目标颜色模型的变换系数。 将RAW数据转换为标准颜色模型中的数据，并使用变换系数将标准颜色模型中的数据转换为目标颜色模型中的数据。 对于各种亮度级别重复该过程并组合成查找表，以有效地将RAW数据转换为目标颜色模型中的数据，以获得各种亮度级别。
