1Speed
If high frame rate rendering is performed, then visual quality and smoothness are improved, but power consumption increases significantly
Solution Approach 1:
The patent segments the frame rendering process into two distinct paths: original frame rendering for key frames and predicted frame generation for intermediate frames. This segmentation allows the system to maintain high frame rates by inserting predicted frames while reducing the computational burden on the GPU, thereby lowering power consumption.
Solution Approach 2:
The patent performs preliminary action by pre-calculating prediction information (such as motion vectors and depth data) from original frames before generating predicted frames. This preliminary processing enables efficient predicted frame generation without requiring full rendering pipelines, thus reducing real-time power consumption while maintaining high frame rates.
2Use of energy by moving object
If frame prediction is applied to reduce power consumption, then battery life is extended, but visual quality may deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors rendering performance and power consumption metrics. Based on this feedback, it dynamically adjusts the ratio of original frames to predicted frames, ensuring that visual quality remains acceptable while optimizing power consumption. The feedback loop allows the system to maintain reliability by switching to more original frames when quality degradation is detected.
Solution Approach 2:
The patent applies local quality by selectively rendering different regions or elements of frames at different quality levels. Critical regions (such as foreground objects or areas with high motion) are rendered with full quality using original frames, while less critical regions use predicted frames. This approach maintains overall visual quality while reducing power consumption through selective prediction.
