Abstract:
In one embodiment, a method includes: obtaining a first image of a scene while an illumination component is set to an inactive state; obtaining a second image of the scene while the illumination component is set to a pre-flash state; determining one or more illumination control parameters for the illumination component for a third image of the scene that satisfy a foreground-background balance criterion based on a function of the first and second images in order to discriminate foreground data from background data within the scene; and obtaining the third image of the scene while the illumination component is set to an active state in accordance with the one or more illumination control parameters.
