1. A camera system, comprising: an image sensor configured to convert light incident upon the image sensor into RGB image data; an image signal processor (“ISP”) configured to: access a set of linear 3D color points corresponding to an input color space; generate a color-mapped linear 3D color look-up table (“LUT”) based on the set of linear 3D color points; generate a gain curve based on the RGB image data; apply 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 apply 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 a memory configured to store the tone-mapped color-mapped linear 3D color LUT and the tone-mapped and color-mapped output image data.
