Abstract:

Methods and apparatus improve static region detection in an imaging pipeline. An imaging pipeline may perform detection of static regions of an image at multiple stages of the pipeline. For example, as static regions may be eliminated from further processing by the imaging pipeline, static region detection performed at an early stage of the pipeline may provide for maximized power savings. As images early in the pipeline may contain artifacts inhibiting detection of some static regions, additional static region detection may be performed after further image processing. For example, static region detection may be performed for a second time after some filtering is applied to images in the pipeline. Regions previously characterized as dynamic may be characterized as static later in the pipeline due to a reduction of noise for example provided by the filters, and differences between the static region detection at different positions within the imaging pipeline.
