Claim of US Patent No. 10,582,589

1. A method comprising:illuminating a scene with a first sensing spectrum emitted by a first subset of a plurality of primary light sources;
capturing a first image of the scene while the scene is illuminated with the first sensing spectrum, the first image comprising a plurality of pixels;
illuminating the scene with a second sensing spectrum emitted by a second subset of the plurality of primary light sources;
capturing a second image of the scene while the scene is illuminated with the second sensing spectrum, the second image comprising the plurality of pixels;
generating a color map of the scene assigning a color point in a color space to each of the plurality of pixels based on the first sensing spectrum, the first image, the second sensing spectrum, and the second image;
determining a lighting spectrum based on the color map; and
illuminating the scene with the lighting spectrum emitted by the plurality of primary light sources.
