1. A device comprising: a camera configured to obtain an image; an electromagnetic radiation sensor configured to produce ultra-violet (UV) light data and infrared (IR) light data associated with the image; a sensor processor configured to determine an illuminant type probability from probability data using the UV light data and the IR light data, the illuminant type probability indicating a level of confidence that a light source associated with the image is a particular illuminant type, the sensor processor being configured to classify the light source as the particular illuminant type when the illuminant type probability is above a confidence threshold; and an auto-white balance unit configured to adjust auto-white balance with the illuminant type probability.
