Processor-Based Transmissive Display Correction Within a Bounded Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image stabilization techniques for transmissive display devices, such as augmented reality (AR) devices, often result in blurred visual recognition when the relative position between the device and the user's eye changes, especially during movements like running. These techniques may fail to appropriately display images due to incorrect positioning adjustments.
Innovation Solution
A processor is configured to derive a new display position for the image based on the initial position and the change in the relative position between the transmissive display device and the user's eye. If the new position exceeds a correction region, the processor adjusts the display position to remain within this region, ensuring the image is properly displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display position is changed to cancel relative position changes (image stabilization), then visual blurring is suppressed, but the display image may not be displayed appropriately or may not be displayed at all
Solution Approach 1:
The patent changes the display position parameters within a correction region to stabilize the image. When the calculated second position exceeds the correction region, the system adjusts parameters to set the display position to a third position within the correction region, ensuring both stability and display appropriateness
Solution Approach 2:
The system dynamically adjusts the display position based on real-time relative position changes. It transitions from a fixed correction approach to a dynamic one where the display position is continuously adjusted within the correction region boundaries to maintain both stability and visibility
2Stability of the object's composition
If the display position is adjusted to cancel relative position changes, then image stabilization is achieved, but display quality deteriorates when the calculated position exceeds the correction region
Solution Approach 1:
The patent establishes a correction region in advance and defines preliminary actions for when the calculated second position exceeds this region. The system prepares alternative positions (third position) within the correction region to prevent display quality deterioration before it occurs
Solution Approach 2:
The system continuously monitors the calculated second position and provides feedback to determine whether it exceeds the correction region. Based on this feedback, it automatically adjusts the display position to an appropriate third position within the correction region, maintaining both stability and precision

AI summary
A processor is configured to, based on a change of a relative position between a transmissive display device and a user's eye, derive a second position according to a first position of a display image displayed in a display region of the display device and the change of the relative position, change the first position to the second position in a case in which the second position does not exceed a correction region where a correction of a display position is possible, and change the first position to a third position and display the display image within the correction region in a case in which the second position exceeds the correction region.
