Claim One:
1. A method for calibrating auto white balancing in an electronic camera, comprising: obtaining, using a processor onboard the electronic camera, a plurality of first color values from a respective first plurality of images of a respective plurality of real-life scenes captured by the electronic camera under a first illuminant, the electronic camera including a plurality of initial auto white balance parameters stored in memory onboard the electronic camera and having only one precalibrated auto white balance parameter, the precalibrated auto white balance parameter being associated with a reference illuminant different from the first illuminant; invoking, using the processor, an assumption about a true color value of at least portions of the real-life scenes, the assumption being stored in the memory; and determining, using a self-training module onboard the electronic camera, a plurality of final auto white balance parameters for a respective plurality of illuminants including the first illuminant and the reference illuminant, the self-training module including the processor and machine-readable self-training instructions stored in the memory that, when executed by the processor, perform the step of determining based upon the true color value, average of the first color values, and the initial auto white balance parameters.
