METHOD AND SYSTEM FOR AUTOMATIC WHITE BALANCING

An automatic white balancing method and system. A modification of “color in perspective” white balancing technique is implemented. Rather than a default projection plane used by the typical white balancing technique, the projection plane for a RGB space is automatically selected to allows the projected reference gamuts in the projection plane to be as disjoined as possible, thereby making them as uncorrelated as possible. In turn, automatic white balancing is performed using the color temperature associated with the projected reference gamut most correlated with the projected gamut of an image sensor.
