1. A system for controlling lighting, said system comprising:
a tunable white light source configured to emit a plurality of different light outputs, each light output having an associated spectral composition and corresponding to a separate associated one of a plurality of lighting conditions stored in a lighting condition database; a camera configured to capture images of one or more objects within an environment illuminated by each of said different light outputs from said light source, each image corresponding to a separate associated one of said different light outputs, said camera being configured to process said image and identify one or more attributes of at least one of said objects for each of said different light outputs wherein said camera comprises an image processing module configured to process pixels of each captured image in one or more color spaces to identify values of each pixel for each color space and wherein said image processing module is configured to generate a spatial mapping of CIE x, y color points and luminance for each pixel and identify color values of said at least one object based on said spatial mapping and said light control module is configured to compare sets of color values of said at least one object for each light output with a set of color values corresponding to the true color of said at least one object, wherein, if a set of color values falls within a predetermined tolerance level, said light control module is configured to identify a lighting condition corresponding to a light output associated with said set of color values as an optimal lighting condition; and a light control module configured to identify at least one optimal lighting condition based, at least in part, on a comparison of said attributes of said at least one object for each of said light outputs with attributes corresponding to a true color appearance of said at least one object. |
