Correlated illuminant estimations
Disclosed is a method and apparatus of correlated illuminant estimation between different camera modules on a same electronic device. Example embodiments of automatic white balance of the digital image leveraging the illuminant estimation based on the facial color features are illustrated.
1. An apparatus, comprising:
a first camera mounted on a first side of an electronic device conducting a first illuminant estimation of a first digital image acquired by the first camera; and
a second camera mounted on a side opposite to the first side of the electronic device conducting a second illuminant estimation of a second digital image acquired by the second camera if a confidence level of the first illuminant estimation by the first camera is below a threshold,
wherein the first camera or the second camera conducts a third illuminant estimation based on the first illuminant estimation and the second illuminant estimation.
2. The apparatus of claim 1 , wherein the first camera or the second camera conducts a color correction or enhancement of a digital image acquired by the first camera or the second camera based on the third illuminant estimation.
