Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional display devices often suffer from an image overlapping phenomenon due to limited viewing regions, which can prevent users from perceiving a three-dimensional effect when the disparity between left and right eye views is not optimally managed.
Innovation Solution
A three-dimensional display device that generates multiple intermediate images based on disparity information and user position, using a system comprising an image input unit, shift value deciding unit, intermediate image generating units, and a selection unit to select and display images that correspond to continuous views, thereby preventing image overlapping by adjusting the number and positioning of intermediate images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a limited number of intermediate images are generated, then device complexity is reduced, but image overlapping occurs and three-dimensional effect is degraded
Solution Approach 1:
The patent implements dynamic adjustment of the number of intermediate images based on user position. The system measures user position and adaptively determines the optimal number of intermediate images to generate, allowing the system to maintain high three-dimensional effect quality when needed while reducing computational complexity when user position allows fewer images.
Solution Approach 2:
The patent changes the parameter of intermediate image count based on measured user position. By adjusting this parameter dynamically according to user location, the system optimizes the balance between preventing image overlapping (requiring more images) and reducing device complexity (requiring fewer images).
2Reliability
If more intermediate images are generated to prevent image overlapping, then three-dimensional effect is improved, but processing time and computational load increase
Solution Approach 1:
The system dynamically adjusts the number of intermediate images generated based on real-time user position measurements. When user position indicates risk of image overlapping, the system increases intermediate image count for better prevention. When position is favorable, it reduces the count to minimize processing time and computational load.
Solution Approach 2:
The system performs user position measurement beforehand to determine the optimal number of intermediate images to generate, avoiding unnecessary generation of excessive images when user position already provides sufficient viewing angles, thus reducing processing time while maintaining overlapping prevention.
3Adaptability or versatility
If fixed number of intermediate images are used, then device complexity is reduced, but adaptability to different user positions is limited
Solution Approach 1:
The patent implements a dynamic image generation system that adapts to different user positions by measuring position and adjusting the number of intermediate images accordingly. This dynamic approach provides high adaptability across various user positions while managing device complexity through selective image generation rather than always generating maximum images.
Solution Approach 2:
The system achieves universal adaptability to different user positions through a single flexible framework that can generate varying numbers of intermediate images based on position requirements, rather than requiring separate fixed systems for different position scenarios.

AI summary
A method for displaying a three-dimensional (3D) image in a display panel of a 3D display device is provided. The method includes generating M images corresponding to a maximum disparity in response to input two-dimensional (2D) images and disparity information of the respective 2D images. The 2D images include a left-side image and a right-side image. The method further includes selecting N images from among the M images, providing the selected N images to a display unit, and displaying the provided N images using the display panel.
