    摘要: The present disclosure provides a computer-implemented method of generating a modified color lookup table (CLUT) based on an original image, a profile connection space (PCS) image, and an adjusted image. The method includes, for each PCS pixel of the PCS image, identifying a subset of CLUT nodes corresponding to the PCS pixel. The method also includes identifying a color shift between an original pixel of the original image and an adjusted pixel of the adjusted image, wherein the original pixel and the adjusted pixel are co-located with the PCS pixel. The identified the color shift is associated with each one of the subset of CLUT nodes. For each CLUT node, a combined color shift is determined based on the color shifts associated with the CLUT node. A modified CLUT can be generated based on the combined color shifts computed for each of the CLUT nodes.

    摘要: 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.
