Frame Rendering with Static Pixel Reuse for Mobile Power Reduction

The patent segments pixels into static and dynamic categories based on their motion characteristics. Static pixels that remain unchanged across frames are identified and separated from dynamic pixels, allowing different rendering strategies to be applied to each segment. This segmentation enables the system to perform full shading computation only on dynamic pixels while reusing pixel values for static pixels, thereby reducing overall power consumption while maintaining rendering precision for visually important regions.

The patent applies local quality by differentiating rendering quality across different spatial regions and temporal frames. Instead of uniformly applying high-quality shading computation to all pixels, the system applies full rendering precision only to dynamic pixels and regions that require updates, while using lower-computation reuse methods for static pixels. This local differentiation maintains visual quality where needed while reducing power consumption in static regions.

By segmenting pixels into static and dynamic categories, the patent reduces the total number of shading computations required per frame. Static pixels are identified and their values reused across multiple frames, significantly decreasing the computational load and heat generation. This segmentation allows the system to maintain rendering quality for dynamic regions while avoiding unnecessary computations in static regions that would contribute to overheating.

The patent implements periodic action by updating pixel values only when necessary (i.e., when pixels become dynamic or change state). Instead of performing continuous shading computation for all pixels in every frame, the system periodically updates static pixel regions only when motion or changes are detected. This periodic update strategy reduces cumulative heat generation while maintaining visual quality, as full computation is performed only when required rather than continuously.

The patent applies segmentation by dividing the pixel set into static and dynamic subsets. This allows the rendering pipeline to process only dynamic pixels through the full shading computation path at high frequencies, while static pixels are handled through efficient value reuse. The segmentation reduces the effective workload per frame, enabling the system to maintain high frame rates without being bottlenecked by unnecessary computations on static regions.

The patent implements partial action by performing complete shading computation only on the subset of dynamic pixels that require updates, rather than applying full computation to all pixels. This partial processing approach reduces the total computational burden while maintaining processing speed, as the system performs exactly the amount of computation necessary to maintain visual quality without excessive redundant operations that would slow down frame processing.

The patent segments the rendering workload by identifying and separating static pixels from dynamic pixels. Static pixels are detected and their values reused across frames without performing full shading computation, while dynamic pixels receive complete processing to maintain accuracy. This segmentation dramatically reduces the total number of shading operations required, cutting processing time while preserving rendering accuracy for the dynamic regions that contribute most to visual changes.

The patent applies preliminary action by pre-identifying static pixels and marking them for value reuse before the actual rendering process. By determining which pixels are static in advance (through motion detection or scene analysis), the system can skip shading computation for these pixels entirely during frame generation. This preliminary classification reduces the real-time processing burden and eliminates unnecessary computations, thereby reducing processing time and lag while maintaining rendering accuracy for dynamic elements.
