3D Stereoscopic Display Virtual Surface Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic display devices are not suitable for in-vehicle use, as they can impair driver visibility with 3D images or movies, and lack methods to safely provide stereoscopic information to drivers while driving.
Innovation Solution
A 3D stereoscopic display device that adjusts the distance or orientation of the virtual display surface relative to the screen to improve visibility, using a playback processing unit, stereoscopic display monitor, and screen composition processing unit to generate and output right-eye and left-eye images, allowing the virtual display surface to be positioned backward or forward relative to the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional stereoscopic display device displays a 3D stereoscopic image or movie with ground objects located disorderly, then the stereoscopic effect is enhanced, but the visibility of the screen is impaired
Solution Approach 1:
The patent applies parameter changes by adjusting the virtual display surface distance parameter. The screen composition processing unit modifies the display parameters to position the virtual display surface at an appropriate distance, preventing disorderly ground objects from appearing while maintaining the stereoscopic effect. This resolves the contradiction by changing the display parameter rather than sacrificing either stereoscopic quality or visibility.
2Loss of information
If the virtual display surface is positioned closer to the screen, then the legibility of in-vehicle information is improved, but the focus distance difference increases causing visibility impairment
Solution Approach 1:
The patent uses parameter changes to optimize the virtual display surface distance. The screen composition processing unit adjusts this parameter to achieve an optimal balance where information remains legible while the focus distance difference is minimized, preventing visibility impairment during driving.
3Reliability
If the virtual display surface is positioned farther from the screen, then the focus distance difference is reduced improving safety, but the legibility of in-vehicle information deteriorates
Solution Approach 1:
The patent applies parameter changes by precisely controlling the virtual display surface distance parameter. The screen composition processing unit adjusts this parameter to find the optimal position that ensures driving safety by reducing focus distance difference while maintaining sufficient information legibility for the driver.
