1. A method for determining an illuminant in a captured scene, comprising: sampling the outputs of a sensor array used to capture the scene; applying, to the sampled outputs, first and second color-correction profiles corresponding to first and second illuminants, thereby forming first and second color-corrected sampled outputs; determining a first color variance corresponding to the first color-corrected sampled output; determining a second color variance corresponding to the second color-corrected sa pled output; and selecting the least of the first and second color variance, the least corresponding to the one of the first and second illuminants that approximates the illuminant of the captured scene.
