3D Display Depth Contradiction Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies face issues with user discomfort and fatigue due to excessive depth differences and contradictions when displaying additional information alongside 3D images, as the difference in depth between the main image and additional information can be too great, leading to depth contradictions that cause user fatigue and discomfort.
Innovation Solution
A 3D display device that includes a display region candidate decider, a depth suitability determiner, and an image composer, which determines if the depth difference between the main image and additional image is within a predetermined tolerance range and composites the images accordingly to avoid depth contradictions, ensuring the additional image is displayed within suitable depth ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information is superimposed on the 3D image to improve usability, then information completeness is improved, but depth contradiction increases causing user discomfort and fatigue
Solution Approach 1:
The patent changes the depth parameter of the additional information to match the depth of the main image. By adjusting the depth parameter of superimposed information (such as rulers or measurement data) to be consistent with the 3D image depth, the system prevents depth contradictions while maintaining information completeness, thereby eliminating user discomfort and fatigue
Solution Approach 2:
The patent creates an equipotential depth environment by making the depth of additional information equal to the depth of the main image. This equipotential approach ensures that all displayed elements exist at the same depth plane, preventing conflicting depth perceptions that cause user discomfort while preserving the usefulness of additional information
2Loss of information
If additional image is displayed outside viewing angle in outer frame portion, then information accessibility is improved, but depth difference becomes excessive causing user fatigue
Solution Approach 1:
The patent adjusts the depth parameter of additional information displayed in outer frame portions to match the depth of the main image content. This parameter adjustment ensures that even when information is placed outside the main viewing angle, the depth consistency is maintained, preventing excessive depth differences that would cause user fatigue

AI summary
A three-dimensional display device configured to display a main image and an additional image on a screen includes a display region candidate decider that decides one candidate region from a plurality of region candidates for the additional image to be superimposed on the main image on the screen, a depth suitability determiner that determines whether a difference between a depth of the main image displayed at a boundary region and a depth of the additional image is within a predetermined tolerance range, and an image composer that, when the difference in depth between the depth of the main image displayed at the boundary region and the depth of the additional image is within the tolerance range, superimposes the additional image upon the main image at the candidate region, thereby composing a composite image of the main image and the additional image, and displays the composite image on the screen.
