Contrasting Visual Overlay for Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems face challenges in making text and graphics overlays visible without obstructing the background image, as conventional methods like increasing size or adding shadows can lead to further obstruction of critical information.
Innovation Solution
The development of high visibility overlay systems that use contrasting elements, calculated based on the observer's field of view and visual acuity, to create overlays that are discernible without increasing the size or obstructing the background, utilizing display configuration data and observer field of view information to construct high visibility elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the size of overlaid text or graphics is increased to improve visibility, then the visibility of the overlay is improved, but the obstruction of critical information in the displayed image increases
Solution Approach 1:
The patent applies color changes by using outlines or shadows with contrasting colors (e.g., white outlines or black shadows) around the overlaid text or graphics. This creates visual contrast that enhances the visibility of the overlay elements without requiring an increase in their size, thereby avoiding obstruction of the background image while maintaining discernibility.
2Illumination intensity
If outlines or shadows are added to offset overlaid elements for visibility, then the visibility of the overlay is improved, but the obstruction of critical information in the displayed image increases
Solution Approach 1:
The patent uses color changes through outlines or shadows with contrasting colors to enhance overlay visibility. The outlined or shadowed elements provide visual separation from the background, improving discernibility without requiring larger element sizes that would block more background information.
3Difficulty of detecting and measuring
If the size of overlaid text or graphics is increased to improve visibility, then the discernibility of the overlay is improved, but the critical information in the displayed image is further obstructed
Solution Approach 1:
The patent applies color changes through contrasting outlines or shadows around overlay elements. This enhances the discernibility of text or graphics without increasing their size, thereby preventing loss of critical background information while maintaining clear visibility of the overlay content.

AI summary
A highly visible overlay system may include a display system and contrasting visible element configuration components configured to define contrasting visible elements. An imaging component is configured to capture an image of a target scene for display. A processing component is configured to construct the plurality of contrasting visual elements in accordance with a visual acuity factor, and generate an electronic overlay constructed of the contrasting visual elements. A display component is configured to display the constructed overlay in combination with the image of the target scene, with the overlay being displayed as an overlay on the image of the target scene. The contrasting visual elements may include a white block and a black block, configured to satisfy visual acuity factor, display configuration and field of view information.
