AR Glasses Visibility Control for ROI-Based Viewing and Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glasses-type information display devices, such as augmented reality devices, face issues with image quality being affected by the user's region of interest, leading to inappropriate visibility for observers.
Innovation Solution
A control device and method that acquires the user's region of interest, adjusts the visibility of real and projected images based on this interest, and records images with unchanged visibility using a visibility change unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the visibility of real image or projected image is changed based on user's region of interest, then the user can visually recognize the image with appropriate visibility, but the recorded image quality becomes inappropriate for observers
Solution Approach 1:
The patent segments the image processing into two distinct paths: one for real-time display to the user (where visibility is adjusted based on region of interest) and one for recording (where visibility is maintained unchanged). This segmentation allows the system to satisfy both the user's need for optimized visibility and the observer's need for consistent image quality in recorded content.
Solution Approach 2:
The patent applies different quality characteristics to different output destinations: the displayed image receives local quality adjustment (visibility modification) tailored to the user's viewing needs, while the recorded image maintains uniform quality without visibility changes. This local quality differentiation resolves the contradiction between user-specific optimization and observer-appropriate consistency.
2Illumination intensity
If the visibility change unit changes visibility of projected image, then the user can see the projected image with optimized visibility, but the recorded projected image has inconsistent quality for observers
Solution Approach 1:
The patent implements preliminary action by capturing the projected image before visibility changes are applied, and separately capturing the real image. By recording these images in advance with their original visibility states, the system ensures that recorded content maintains consistent quality for observers, while still allowing real-time visibility adjustment for user viewing.
Solution Approach 2:
The patent creates a copy of the projected image that is recorded separately from the real-time display stream. This copied image retains the original visibility characteristics, ensuring that recorded content remains consistent and appropriate for observers, while the original stream can be modified for optimal user viewing experience.
3Adaptability or versatility
If the system records images with visibility changes applied, then the user experience during viewing is optimized, but the recorded image is not suitable for general observation
Solution Approach 1:
The patent introduces dynamics by making the image processing path flexible: the system dynamically selects whether to apply visibility changes based on the destination (display vs. recording). For user display, visibility is dynamically adjusted according to region of interest, while for recording, the original image is preserved. This dynamic approach allows the system to adapt to different operational modes while maintaining observer convenience.

AI summary
A control device includes at least one processor, in which the processor acquires a region of interest of a user, performs, for at least one image of a real image visually recognized by the user through a transmission unit or a projected image projected onto the transmission unit and visually recognized by the user, a control to change visibility by the user based on a relationship between at least one of the real image or the projected image and the region of interest, by a visibility change unit that changes the visibility, and records the projected image in which the visibility is not changed by the visibility change unit.
