    • Modifying a color lookup table includes receiving a first image, a first color lookup table (CLUT) indexed in a first image color space, and a second CLUT indexed in a colorimetric space. Tracer pixels from the second CLUT are generated and retained, each tracer pixel including color coordinates of a corresponding unique node in the first CLUT. Tracer pixels are inserted into the first image, and tracer pixels are tracked. Color adjustments are made using image editing software to generate an adjusted combined image having adjusted tracer pixels. The adjusted tracer pixels are extracted. The second CLUT is converted to a third CLUT having a size N1×N2×N3×N4 by replacing each of the output-device color coordinates of the second CLUT nodes by modified device color coordinates computed from the adjusted color coordinates of the adjusted tracer pixels.
    • 修改颜色查找表包括接收第一图像,在第一图像颜色空间中索引的第一颜色查找表(CLUT)和在比色空间中索引的第二CLUT。 生成并保留来自第二CLUT的跟踪器像素,每个示踪器像素包括第一CLUT中对应的唯一节点的颜色坐标。 跟踪器像素被插入到第一图像中,跟踪像素被跟踪。 使用图像编辑软件进行颜色调整,以产生具有调整的跟踪像素的经调整的组合图像。 提取调整后的跟踪像素。 第二CLUT被转换成具有大小为N1×N2×N3×N4的第三CLUT,通过从经调整的跟踪像素的调整色坐标计算出的修改的设备颜色坐标替换第二CLUT节点的每个输出设备颜色坐标 。
