Eyewear Display Vignette Gradient for Immersive Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable eyewear devices with see-through displays struggle to provide an immersive and distortion-free visual experience, especially in uncontrolled regions above and below the primary field of view, due to discoloration and edge distortions.
Innovation Solution
The eyewear device employs multiple visible light cameras and an image processor to capture and process stereoscopic images, applying a vignette gradient to soften edges and compensate for discoloration in uncontrolled regions, thereby enhancing the immersive experience by generating three-dimensional images and adjusting the field of view based on user movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If see-through displays are used in portable eyewear devices, then the user can see through the device while viewing displayed content, but discoloration and edge distortions occur in uncontrolled regions above and below the primary field of view
Solution Approach 1:
The patent applies different processing strategies to different regions of the display. Controlled regions (primary field of view) receive standard image processing, while uncontrolled regions (above and below primary FOV) receive specialized vignette gradient processing to soften edges and reduce discoloration. This local differentiation resolves the contradiction by maintaining see-through functionality while improving image quality specifically in the problematic uncontrolled regions.
Solution Approach 2:
The patent modifies image parameters (brightness, contrast, edge sharpness) in uncontrolled regions through vignette gradient processing. By changing these parameters locally in regions where distortions occur, the system maintains the see-through display functionality while compensating for the discoloration and edge distortions in uncontrolled areas.
2Adaptability or versatility
If multiple cameras and image processing are used to improve immersive experience, then depth perception and field of view adjustment are enhanced, but device complexity increases
Solution Approach 1:
The patent makes the image processor multi-functional by having it perform both standard image processing for the controlled regions and vignette gradient processing for uncontrolled regions. The same processor also handles field of view adjustment based on user movement detection. This consolidates multiple functions into a single component, reducing overall device complexity while maintaining enhanced immersive experience.
Solution Approach 2:
The patent combines the functions of multiple cameras, movement detection, field of view adjustment, and image processing (including vignette gradient application) into an integrated system. By merging these functions and processing them through a unified image processor, the device achieves enhanced immersive experience while managing complexity through integration rather than separate components.

AI summary
Eyewear having a camera capturing images, and an image processor configured to process the images and display the processed image in both controlled and uncontrolled regions on the display. In an example, the image processor applies a vignette gradient to soften edges of the displayed image in the uncontrolled regions, which compensates for any discoloration in the uncontrolled regions. The uncontrolled regions may be located above and below the controlled region.
