HMD Diopter Adjustment Image Distortion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) with diopter adjustment functionality face challenges in image processing, as the distortion correction software becomes unsuitable after diopter setting adjustments, leading to image distortion issues.
Innovation Solution
The HMD incorporates a processor, storage medium, and input device for diopter adjustment, utilizing a mapping table to render images correctly after diopter setting changes, thereby correcting distortion and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diopter adjustment function is incorporated into HMD to accommodate users with different diopter values, then the HMD becomes more lightweight and comfortable, but the image processing software for distortion correction becomes unsuitable after diopter setting adjustments
Solution Approach 1:
The patent implements dynamic image processing by detecting current diopter settings and automatically adjusting distortion correction parameters in real-time. The system transitions from static distortion correction software to a dynamic process that adapts to changing diopter configurations, ensuring reliable image quality across all adjustment positions.
Solution Approach 2:
The patent changes the parameters of image processing software based on diopter settings. By detecting the current diopter value and corresponding distortion characteristics, the system adjusts rendering parameters dynamically, allowing the same software to maintain effective distortion correction across varying diopter conditions.
2Volume of stationary object
If diopter adjustment is implemented to reduce internal space needed for corrective lenses, then HMD design becomes more compact, but distortion correction software becomes obsolete after adjustment
Solution Approach 1:
The system performs self-adjustment by automatically detecting diopter settings and configuring appropriate distortion correction parameters without requiring manual software reconfiguration. This self-service mechanism eliminates the need for complex manual recalibration while maintaining compact design.
Solution Approach 2:
The patent implements a feedback loop where the system detects current diopter settings and uses this information to automatically adjust distortion correction parameters. This closed-loop control simplifies the overall system by eliminating manual intervention while maintaining accurate image correction across all diopter positions.
