Stereoscopic Display Adjusting Image Disparities for Multiple Viewers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto-stereoscopic displaying devices cannot provide customized 3D image effects to multiple viewers with different perspectives, as they only offer a consistent 3D image effect regardless of the viewer's position.
Innovation Solution
A stereoscopic displaying method and device that adjusts image disparities based on viewer-specific depth setting commands, using a stereoscopic display with multiple view angles and a viewer tracking module to customize the 3D image depth for each viewer by adjusting images projected through lenticular lenses or parallax barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional auto-stereoscopic displaying device uses a lenticular lens to project different images to different view angles, then a 3D image effect can be perceived by viewers, but the device cannot provide customized 3D image effects to multiple viewers with different perspectives
Solution Approach 1:
The patent implements dynamic adjustment of image disparity parameters based on real-time viewer position detection. The system continuously tracks viewer locations and automatically modifies the 3D image parameters projected to each view angle, transforming a static display system into a dynamic one that adapts to viewer movements and preferences.
Solution Approach 2:
The system employs feedback mechanisms by detecting viewer positions and using this information to adjust the 3D image effects. The detected viewer positions feed back to the image processing module, which then modifies the disparity parameters accordingly, creating a closed-loop control system that optimizes the 3D experience for each viewer.
2Ease of operation
If the stereoscopic display adjusts images according to multiple viewers' depth setting commands, then each viewer can perceive personalized 3D image depths, but the processing complexity increases
Solution Approach 1:
The patent segments the image processing task by creating separate processing channels for different view angles and viewers. Each viewer's depth setting command is processed independently for their specific viewing position, allowing personalized 3D effects without requiring complete reprocessing of the entire image for all possible viewers simultaneously.
Solution Approach 2:
The system changes image parameters dynamically based on viewer-specific depth settings. By modifying disparity parameters, brightness, and other visual attributes according to each viewer's preferences and position, the system achieves personalized 3D effects through parameter adjustment rather than complete image regeneration.
3Adaptability or versatility
If the system provides consistent 3D image effect to all viewers, then the device complexity is low, but multiple viewers cannot experience customized 3D effects according to their individual preferences
Solution Approach 1:
The patent applies local quality by providing different 3D image characteristics to different spatial regions and viewers. Each view angle and viewer position receives customized image processing with appropriate disparity parameters, rather than applying a uniform 3D effect to the entire display area. This allows precise control over the 3D experience for each viewer based on their location and preferences.

AI summary
An image displaying method includes the following steps. A first depth setting command is received from a first viewer who observes a first disparity between two images through two view angles in front of a stereoscopic display having N view angles. A second depth setting command is received from a second viewer who observes a second disparity between two images through another two view angles. The stereoscopic display is configured to adjust at least one image among its N view angles, thereby making the first disparity different from the second disparity.
