Abstract :
A new algorithm of automatic white balance for electronic images has been developed. This algorithm uses fuzzy logic rules for determination of the color parameters in order to minimize the color temperature difference of various light sources. This algorithm has been implemented in a newly designed electronic still camera, and resulted in highly improved image quality
