Stereoscopic Display Parallax and Blurring Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic display technologies struggle to effectively enhance the sense of perspective in virtual worlds by adjusting parallax and blurring levels without changing object positions, leading to limited depth perception and discomfort in viewers.
Innovation Solution
A display control program and apparatus that sets parallax and blurring levels dynamically, allowing for adjustable blurring based on parallax changes, enabling the generation of stereoscopic images with varying levels of blurring to emphasize perspective, using a combination of unblurred and blurred images and a 3D adjustment mechanism for user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parallax is adjusted to enhance stereoscopic display, then depth perception is improved, but the sense of perspective does not significantly differ without blurring
Solution Approach 1:
The patent applies parameter changes by adjusting both the parallax amount and the blurring level as independent parameters. The blurring level is specifically changed to enhance the sense of perspective, while parallax controls depth perception. This dual-parameter approach resolves the contradiction by allowing depth perception to be maintained through parallax while perspective is enhanced through additional blurring control.
Solution Approach 2:
The patent applies local quality by selectively applying different blurring levels to different depth regions in the stereoscopic image. Objects at different depths receive different amounts of blurring based on their distance from the focal plane, creating a more realistic depth-of-field effect that enhances perspective without compromising overall depth perception.
2Ease of operation
If multiple parameters are adjusted to enhance perspective, then viewing comfort is improved, but device complexity increases
Solution Approach 1:
The patent applies feedback by automatically adjusting the blurring level based on the set parallax amount and depth information of objects in the scene. The system calculates appropriate blurring levels using feedback from depth maps or depth buffers, eliminating the need for manual adjustment of multiple parameters while maintaining viewing comfort.
Solution Approach 2:
The patent applies self-service by enabling the display control apparatus to automatically determine and apply appropriate blurring levels without user intervention. The system uses depth information and parallax settings to self-adjust the blurring parameters, reducing device complexity from the user perspective while maintaining enhanced perspective effects.

AI summary
A parallax with which a virtual world is stereoscopically displayed is set, and in accordance with the parallax, a level of blurring with which the virtual world is stereoscopically displayed is set. Then, a stereoscopic image in which the virtual world is stereoscopically displayed is generated on the basis of the parallax by blurring at least part of the virtual world in accordance with the level of blurring.
