Global Image Enhancement Control for 3D Video Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D video display systems face issues with image quality when displaying stereo images across multiple displays, as independent processing of left and right eye views can result in unintended image differences, leading to reduced quality and consumer discomfort, and existing calibration methods are static and do not account for coordinated enhancements across multiple displays.
Innovation Solution
A method and apparatus that utilize individually collected image enhancement statistic information from multiple processor cores to generate global image enhancement control information, ensuring consistent enhancements across all displays by sharing or combining statistic information to apply adaptive corrections to both left and right eye views or multi-view frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If independent adaptive enhancements are applied to left and right eye views, then image quality for each view is improved, but unintended image differences occur between views causing eye strain and reduced 3D quality
Solution Approach 1:
The patent combines the enhancement processing of left and right eye views by using a common reference frame (from a previous time period) for both views. This merging approach ensures that both views undergo consistent enhancement operations, maintaining temporal coherence and preventing unintended differences between stereoscopic pairs, thereby resolving the contradiction between individual view quality and overall 3D quality.
Solution Approach 2:
The patent performs enhancement operations using reference frame data from a previous time period before processing the current frame. This preliminary action of using historical reference data allows the system to pre-determine enhancement parameters that will be applied consistently to both left and right views, preventing temporal inconsistencies and ensuring coherent 3D image quality.
2Productivity
If multiple processor cores process different portions of a logical frame across multiple displays, then processing capacity is improved, but image enhancement consistency deteriorates due to lack of communication between processors
Solution Approach 1:
The patent introduces a host processor as an intermediary that collects enhancement statistic information from multiple GPU processor cores and distributes common enhancement control data back to them. This intermediary role ensures that while each GPU maintains independent processing capacity, they all operate with consistent enhancement parameters derived from global statistics, thereby maintaining image enhancement consistency across multiple displays.
Solution Approach 2:
The patent implements a universal enhancement control mechanism where the host processor generates common enhancement control data that is universally applied across all GPU processor cores. This multi-functional approach allows the system to maintain both specialized processing capabilities of individual GPUs and overall consistency through a centralized control that serves all processors uniformly.
3Manufacturing precision
If host processor analyzes pixel data for full frame enhancement statistics, then global image enhancement control is improved, but bandwidth consumption and processing efficiency deteriorate
Solution Approach 1:
The patent extracts only the necessary enhancement statistic information from each GPU processor core instead of transferring complete pixel data to the host processor. By taking out only the essential statistical data needed for global enhancement control, the system achieves comprehensive image enhancement management while minimizing bandwidth consumption and processing overhead on the host processor.

AI summary
A method and apparatus for processing video utilize individually collected image enhancement statistic information from differing processor cores for a same frame or multi-view that are then either shared between the processor cores or used by a third processor core to combine the statistical information that has been individually collected to generate global image-enhancement control information. The global image enhancement control information is based on a global analysis of both left and right eye views for example using the independently generated statistic information for a pair of frames. Respective image output information is produced by each of the plurality of processor cores based on the global image enhancement control information, for display on one or more displays.
