Abstract
Systems and methods for determining a colorimetric value from color measurements for multiple ambient color sensors which for each color measurement, in various approaches, select a lighting cluster similar to the color measurement and determine whether the color measurement is valid or invalid based on a calculated similarity between the color measurement and the selected lighting cluster, calculate a weight for the color measurement for combination with other color measurements based on the calculated similarity between the color measurement and its selected lighting cluster, determine whether the color measurement is valid or invalid based on perceptual color space distances for the color measurement for multiple reference light sources, and/or calculate a weight for the color measurement for combination with other color measurements based on the perceptual color space distances for multiple reference light sources.
