Glasses Display Parallax Compensation Using Partial Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality devices, parallax between the user's eye and the camera causes a deviation between the real image and the captured image, leading to a sense of incongruity for the user.
Innovation Solution
A processor in the glasses-type display device cuts out a partial image from the captured image based on the parallax between the user's eye and the camera, determining the range and display size of this partial image to align it with the real image visually recognized by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the captured image is displayed directly without adjustment, then the display process is simple, but parallax causes deviation between the real image and captured image
Solution Approach 1:
The captured image is divided into a first captured image (from the camera) and a second captured image (from the illuminating device). By segmenting the imaging sources and applying different processing to each, the patent achieves precise alignment compensation for parallax while maintaining manageable processing complexity through targeted rather than global processing.
Solution Approach 2:
The patent performs preliminary alignment processing on the captured images before final display. By pre-calculating and applying parallax compensation transformations to align the first and second captured images with the real image, the system eliminates deviation upfront, avoiding the need for complex real-time adjustment during display.
2Ease of operation
If the entire captured image is displayed, then the field of view is complete, but the user's visual focus is diluted across the entire visual field
Solution Approach 1:
The patent applies local quality enhancement by displaying the aligned captured image primarily in the peripheral visual field while keeping the center visual field for the real image. This creates different functional zones: the periphery shows the aligned captured content for contextual awareness, while the center maintains clear real-world vision for primary focus, optimizing both information delivery and visual comfort.
Solution Approach 2:
The patent transitions from a single-plane display approach to a multi-dimensional visual arrangement by positioning the captured image in the peripheral visual field dimension rather than competing for the central focal dimension. This spatial differentiation allows simultaneous access to both real-world and captured content without visual conflict, improving operational efficiency.

AI summary
A processor, which is included in a glasses-type display device that allows at least one eye of a user to visually recognize a real space and that displays a captured image obtained by imaging the real space with a camera, performs display processing of displaying a partial image, which is a partial region of the captured image captured by the camera, in a manner visually recognizable by the user based on a parallax between the eye of the user and the camera.
