1. A method of processing a captured image of a scene with a captured-image processing apparatus, said method comprising the steps of: determining photographic parameters of the scene with the captured-image processing apparatus; determining, with the captured-image processing apparatus, if the parameters meet pre-defined criteria, flash-no-flash white balance information for the captured image based on both a no-flash image of the scene captured at ambient light and on a flash-image of the scene captured using a flash illuminant; estimating the reliability of the determined flash-no-flash white balance information with the captured-image processing apparatus; and determining, with the captured-image processing apparatus, if the parameters do not meet the pre-defined criteria or the reliability is lower than a pre-defined threshold, white balance information applicable to the captured image using a default white balance method.
