Head-Mounted Display Image Generation Device Using Nested Data Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images corrected for lens distortion in head-mounted displays are still distorted when viewed outside the display and have unused areas in rectangular transmission formats, leading to inefficient data transmission and user-friendliness issues.
Innovation Solution
Embedding a different image into the unused area of the corrected image format for head-mounted displays, allowing for efficient data transmission and improved user experience by utilizing the existing communication interface for both primary and embedded images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an image is corrected for lens distortion to be displayed on a head-mounted display, then the image appears undistorted when viewed through the lenses, but the corrected image shape becomes approximately circular with unused corner areas in rectangular format
Solution Approach 1:
The patent embeds a secondary image (such as UI elements, icons, or additional information) within the unused circular area of the corrected image that is transmitted in rectangular format. This nesting approach allows the secondary image to be placed in the otherwise wasted corner areas without interfering with the primary corrected image, thereby utilizing the unused space effectively.
Solution Approach 2:
The patent utilizes the spatial dimension created by the mismatch between the circular corrected image and rectangular transmission format. By embedding additional image data in the unused angular dimensions (corners) of the rectangular format, the system transforms a two-dimensional waste area into a useful additional information carrier.
2Manufacturing precision
If an image is corrected for lens distortion, then it appears correct when viewed through head-mounted display lenses, but it remains distorted when viewed outside the display context
Solution Approach 1:
The patent performs preliminary embedding of the corrected image and additional image data into a rectangular format before transmission. This preliminary action ensures that when the image is displayed outside the head-mounted display context, the embedded additional information (which may include verification data or alternative representations) is available to help verify or interpret the corrected image content.
Solution Approach 2:
The patent introduces an intermediary rectangular format that bridges between the circular corrected image and external display systems. This intermediary format contains both the corrected image and embedded additional information, allowing external systems to access and verify image content without requiring the actual head-mounted display lenses.
3Reliability
If only the corrected image is transmitted to the head-mounted display, then the display function is fulfilled, but data transmission efficiency is reduced due to unused areas
Solution Approach 1:
The patent merges the primary corrected image with additional image data (such as UI elements, icons, or supplementary information) into a single rectangular data stream. This combination allows both the essential corrected image and additional useful information to be transmitted together through the same communication interface, eliminating the need for separate transmission channels and improving overall data transmission efficiency.
Solution Approach 2:
The patent makes the transmitted rectangular image data multi-functional by embedding multiple types of information within it. The same data stream serves both as the corrected image for display through the head-mounted display lenses and as a carrier for additional image data that can be used for user interface elements, information overlay, or verification purposes, thereby maximizing the utility of the transmitted data.

AI summary
An image generating section 720 reads image data from an image storing section 710 to generate an original image in keeping with the attitude of a head-mounted display. A lens distortion correcting section 730 generates a primary image by correcting beforehand the original image in a manner canceling out the distortion thereof that appears when viewed through lenses of the head-mounted display. A different image embedding section 750 generates an embedded image by embedding a different image into an unused area of a rectangular format for transmitting the primary image. An HDMI transmitting section 760 transfers the embedded image to the head-mounted display.
