HDR Video Rotation Animation Pipeline Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotation animations in electronic devices require significant processing power and often suffer from flicker issues due to differences in display parameters between graphic and display processors, particularly when handling high dynamic range (HDR) video playback.
Innovation Solution
A method that determines the format of video playback, bypassing certain components of the display processor pipeline for HDR video to reduce processing load and prevent quality degradation, by loading the frame rotation animation into a second portion of the pipeline if it's in HDR format, and into a first portion if it's not, thereby optimizing power consumption and animation quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If frame rotation animation is processed through the complete display processor pipeline, then animation quality is maintained, but processing power consumption increases significantly
Solution Approach 1:
The display processor pipeline is divided into multiple stages, and the patent selectively applies frame rotation animation processing only to specific stages based on video format. For HDR videos, the animation is applied only in the HDR processing stage rather than the complete pipeline, reducing redundant processing operations and energy consumption while maintaining visual quality.
Solution Approach 2:
The patent changes the processing parameters based on video format detection. When HDR video is detected, the system adjusts the pipeline configuration to apply frame rotation animation only in the HDR processing path, whereas standard video undergoes complete pipeline processing. This parameter adaptation optimizes energy efficiency without compromising animation quality for each video type.
2Device complexity
If frame rotation animation is applied uniformly across all video formats, then processing is simplified, but flicker issues occur due to mismatched display parameters
Solution Approach 1:
The patent implements local quality processing by applying different frame rotation animation treatments to different video formats within the same pipeline. HDR videos receive specialized processing in the HDR stage with appropriate color space and brightness parameter adjustments, while standard videos receive conventional processing. This localized adaptation eliminates flicker caused by parameter mismatches between graphic and display processors.
Solution Approach 2:
The system dynamically adjusts the processing path based on real-time video format detection. When HDR video is detected, the pipeline configuration changes to apply animation only in the HDR processing stage; for standard video, the complete pipeline is used. This dynamic adaptation ensures optimal display stability for each format while avoiding the complexity of maintaining multiple fixed processing configurations.
3Use of energy by moving object
If frame rotation animation processing is optimized for HDR format by bypassing certain pipeline stages, then power consumption is reduced, but processing steps may be insufficient
Solution Approach 1:
The patent performs preliminary detection of video format (HDR or standard) before initiating frame rotation animation processing. Based on this detection, the system pre-configures the appropriate processing path: for HDR videos, it sets up the optimized path that applies animation only in the HDR processing stage; for standard videos, it configures the complete pipeline path. This preliminary action ensures that the most efficient adequate processing path is selected, reducing unnecessary power consumption while maintaining processing completeness.

AI summary
In some aspects, the present disclosure provides a method for high dynamic range (HDR) video rotation. The method includes receiving, by a display processor, an indication that a frame rotation animation process for video playback has been initiated, the display processor comprising a display processor pipeline. The method also includes determining whether the video playback is an HDR format or another format. In response to the determination and receiving the indication: bypassing a loading of the frame rotation animation into a first portion of the display processor pipeline, and loading the frame rotation animation into a second portion of the display processor pipeline if the video playback is in an HDR format.
