Abstract:
Embodiments of the present invention are operable to perform automatic white balancing operations on images captured by a camera system through the use of weights derived through crowdsourcing procedures. Embodiments of the present invention use crowdsourced weight data resident on the camera system in combination with sampled image data of a captured image to determine a likely illuminant source. When performing automatic white balancing operations on the captured image, embodiments of the present invention may also compute a confidence score which may present the user with a choice to either use the likely illuminant determined using the crowdsourced weights or the camera system's default or normal automatic white balancing correction algorithm.
