3D color mapping and tuning in an image processing pipeline

A method, comprising:

• converting, by a camera, light incident upon an image sensor of the camera into raw RGB image data;
• accessing, by an image signal processor (“ISP”) of the camera, a set of linear 3D color points corresponding to an input color space;
• generating, by the ISP of the camera, a color-mapped linear 3D color look-up table (“LUT”) based on the set of linear 3D color points;
• generating, by the ISP of the camera, a gain curve based on the RGB image data;
• applying, by the ISP of the camera, the gain curve to the color mapped linear 3D color look-up table to generate a tone-mapped color-mapped linear 3D color LUT;
• and
• applying, by the ISP of the camera, the tone-mapped color-mapped linear 3D color LUT to the RGB image data to generate tone-mapped and color-mapped output image data;
• and
• storing, by a memory of the camera, the tone-mapped color-mapped output image.
