AR Display Image Adjustment via Virtual Coordinate Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality (AR) devices, such as AR glasses, face limitations in adjusting display content due to small screen sizes, where zooming in only shows part of the content, and further adjustments are not possible, making it inconvenient to view content clearly without obstructing the user's view.
Innovation Solution
A display image adjustment method and device that converts received image data into a coordinate system, allowing initial image adjustment based on user input commands, such as zoom and shift, within a virtual adjustment coordinate region larger than the active display region, enabling the image to be resized and repositioned for clearer viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image is zoomed in on the small display screen, then the content visibility is improved, but the display region can only show part of the content and cannot be further adjusted
Solution Approach 1:
The patent implements dynamic adjustability of the display image by allowing users to modify image parameters in real-time. The control unit receives user input and dynamically adjusts at least one parameter of the display image, enabling the image to adapt to different viewing needs and scenarios, thus resolving the contradiction between initial content visibility and subsequent adjustability.
2Area of stationary object
If the display region is increased to show more content, then the content coverage is improved, but the image becomes smaller and harder to view clearly
Solution Approach 1:
The system provides dynamic parameter adjustment that allows users to optimize the balance between display area and image clarity based on their specific needs. By enabling real-time modification of display parameters, users can achieve the desired trade-off between showing more content and maintaining readable image quality.
3Ease of operation
If the image is adjusted to avoid blocking the user's view, then the viewing comfort is improved, but the display content may become less visible
Solution Approach 1:
The patent enables dynamic adjustment of display image parameters to optimize both viewing comfort and content visibility. Users can modify parameters such as position, size, and transparency in real-time, allowing them to find the optimal balance between avoiding obstruction of their real-world view and maintaining clear visibility of the displayed content.

AI summary
The disclosure provides a display image adjustment method and an augmented reality display device. The display image adjustment method includes the following steps. Received image data is converted to a coordinate system of the augmented reality display device to obtain initial coordinate information. An initial image is provided to an active display region of the augmented reality display device based on the initial coordinate information. The initial coordinate information is adjusted in a virtual adjustment coordinate region to obtain adjusted coordinate information when an adjustment command is received. An adjusted image is provided to the active display region of the augmented reality display device based on the adjusted coordinate information. The display image adjustment method and the augmented reality display device proposed by the disclosure may adjust display content of the AR display device according to user's needs.
