Abstract
Consistent white balance between successive similar digital images of a scene is provided by comparing the digital images and, if they are sufficiently similar, maintaining substantially the same white balance setting in a second digital image as in a first digital image. The method is applicable to, for example, mixed-illuminant situations and may be implemented in both still-capture and video digital imaging devices.
