3D Display Crosstalk Reduction via Pixel Density Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional display apparatuses suffer from image-quality deterioration due to crosstalk, which occurs when observation angles of the left and right eyes are not properly aligned, causing intermingling of left-eye and right-eye images.
Innovation Solution
A display apparatus with a light-beam control section that controls light beams to display a plurality of observing-point images, including two or more first observing-point images and one or more second observing-point images, where the number of pixels in each second observing-point image is smaller than in each first observing-point image, reducing crosstalk by interpolating pixel information between left-eye and right-eye images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple observing-point images are displayed to enable three-dimensional viewing from different angles, then the three-dimensional display capability is improved, but crosstalk between left-eye and right-eye images increases causing image-quality deterioration
Solution Approach 1:
The patent segments the displaying area into multiple regions, each dedicated to a specific observing point. By dividing the display into distinct segments (first displaying area for left-eye, second displaying area for right-eye, and additional areas for intermediate observing points), the system prevents crosstalk while maintaining multi-angle three-dimensional viewing capability. Each segment displays images optimized for its specific observing point, eliminating the intermingling of left-eye and right-eye images.
Solution Approach 2:
The patent applies local quality by providing different image resolutions and pixel densities for different observing points. The first and second displaying areas (for left and right eyes) use full-resolution images, while intermediate observing points use lower-resolution interpolated images. This local differentiation ensures that each observing point receives appropriately optimized image quality, reducing crosstalk while maintaining overall three-dimensional display performance.
2Object-affected harmful factors
If the number of pixels in second observing-point images is reduced compared to first observing-point images, then crosstalk is reduced, but the resolution for intermediate observing points may deteriorate
Solution Approach 1:
The patent applies partial action by providing full-resolution images only for the primary left-eye and right-eye observing points, while providing reduced-resolution interpolated images for intermediate observing points. This partial differentiation reduces overall crosstalk while maintaining acceptable image quality for intermediate views. The system performs sufficient action for critical observing points (left and right eyes) while using reduced action for less critical points (intermediate angles), optimizing the trade-off between crosstalk reduction and image resolution.
