Stereoscopic Image Display View Control via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image displays lack the ability to adaptively control the viewing angle and depth information of left-eye and right-eye images in response to a viewer's position, limiting the number of views available to the viewer.
Innovation Solution
A method and system that detect the viewer's position using sensors, adjust rendering parameters for the viewing angle and depth information of left-eye and right-eye images, and dynamically generate and display these images to provide an unlimited number of views based on the viewer's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stereoscopic image display system is used, then the display structure is simple, but the number of views is limited and cannot adapt to viewer position changes
Solution Approach 1:
The patent applies dynamics by making the stereoscopic image parameters dynamic rather than fixed. The system continuously adjusts the viewing angle and depth information of left-eye and right-eye images based on real-time detection of viewer position, enabling unlimited views while maintaining a relatively simple display structure through software-based adaptation.
Solution Approach 2:
The patent implements feedback by using sensors to detect viewer position and using this information to dynamically adjust image rendering parameters. The detected position information feeds back to the image processing unit, which modifies the stereoscopic image parameters accordingly, creating a closed-loop system that adapts to viewer movement.
2Adaptability or versatility
If the stereoscopic image parameters are fixed, then the processing complexity is low, but the viewer experience is limited to a single viewing angle
Solution Approach 1:
The patent makes image processing dynamic by continuously adjusting viewing angle and depth information parameters based on detected viewer position. This allows the system to adapt to different viewing angles and provide an immersive experience while managing processing complexity through efficient parameter adjustment rather than complete image regeneration.
Solution Approach 2:
The patent applies parameter changes by modifying specific parameters of the stereoscopic images (viewing angle and depth information) based on viewer position detection. This approach allows adaptive viewing without requiring complete reprocessing of the entire image, thus balancing adaptability with processing efficiency.
3Adaptability or versatility
If real-time viewer position detection is implemented, then the adaptability to viewer motion is improved, but the system complexity and cost increase
Solution Approach 1:
The patent applies self-service by using sensors integrated into the display system itself to detect viewer position. The system serves itself by automatically adjusting image parameters based on its own sensor data without requiring external complex detection systems, thereby achieving real-time adaptation with moderate system complexity.
4Adaptability or versatility
If the viewing parameters are dynamically adjusted, then the viewer immersion is enhanced, but the processing time and computational load increase
Solution Approach 1:
The patent optimizes processing time by changing only the necessary parameters (viewing angle and depth information) rather than completely regenerating images. This selective parameter adjustment maintains high viewing experience quality while minimizing computational load and processing time requirements.

AI summary
A method of controlling a view of a stereoscopic image and a stereoscopic image display using the same are disclosed. The method of controlling a view of a stereoscopic image includes: detecting a position information of a viewer from an output of a sensor; changing parameters for rendering a viewing angle and a depth information according to the position information; generating a left-eye image and a right-eye image in which a viewing angle and a depth information are changed in accordance with the parameters; and displaying the left-eye image and the right-eye image on a stereoscopic image display.
