3D Display Apparatus Reducing Dead Zones via Depth-Based Image Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display apparatuses suffer from dead zones, where viewers cannot see a 3D image due to crosstalk when changing positions, as images are sequentially arranged, leading to radical differences in image views.
Innovation Solution
A 3D display apparatus and image processing method that generate multi-view foreground and rear ground images with specific arrangement patterns to reduce dead zones, allowing viewers to comfortably watch 3D images from any position by separating and arranging images based on depth information using a multi-view image generator and renderer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multi-view images are arranged sequentially from 1st view to 9th view, then the display structure is simple, but dead zones are generated causing crosstalk when viewer position changes
Solution Approach 1:
The patent segments the multi-view images into foreground images (with depth information less than preset value) and rear ground images (with depth information equal to or higher than preset value). This segmentation allows different arrangement patterns to be applied to different depth layers, resolving the contradiction by creating a more complex but reliable arrangement that eliminates dead zones while maintaining manageable structure through systematic categorization.
Solution Approach 2:
The patent applies different arrangement patterns to different types of images based on their depth characteristics. Foreground images use one arrangement pattern while rear ground images use another pattern, with both patterns shifted by different view numbers. This local differentiation in arrangement quality eliminates dead zones and crosstalk while maintaining overall system organization.
2Adaptability or versatility
If images are arranged with radical difference in views to cover all positions, then viewing coverage is improved, but dead zones occur where two far-separated views are viewed simultaneously
Solution Approach 1:
The patent changes the arrangement parameters by introducing depth-based categorization and differential view shifts. Foreground images are shifted by a first view number while rear ground images are shifted by a second view number (different from the first). This parameter change creates overlapping view coverage that eliminates dead zones while preventing crosstalk through proper depth-layered arrangement.
Solution Approach 2:
The patent adds a depth dimension to the traditional sequential arrangement by separating images into foreground and rear ground layers based on depth information. This dimensional change allows the system to achieve comprehensive viewing coverage without dead zones by arranging images in three-dimensional space rather than simple sequential order.
3Ease of manufacture
If sequential arrangement is used, then the processing method is simple, but the viewer cannot watch 3D image comfortably when position changes
Solution Approach 1:
The patent segments images based on depth information into foreground and rear ground categories, applying systematic but differentiated processing to each segment. This segmentation approach maintains reasonable processing complexity while dramatically improving viewing comfort by eliminating dead zones and crosstalk through depth-aware arrangement.
Solution Approach 2:
The patent introduces depth-based parameter changes in the arrangement process, where foreground and rear ground images are shifted by different view numbers. This parameter differentiation improves viewing comfort across multiple positions while maintaining systematic processing that is not overly complex.

AI summary
A three-dimensional (3D) display apparatus is provided, including an image input device which receives an image and depth information, a multi-view image generator which generates a multi-view foreground image having depth information which is less than a preset depth value, and a multi-view rear ground image having depth information which is equal to or greater than the preset depth value, using the received image and depth information, a multi-view image renderer which performs rendering by arranging the multi-view foreground image according to a first arrangement pattern and the multi-view rear ground image according to a second arrangement pattern, and a display which outputs the rendered multi-view image.
