2D Quality Enhancer for Polarized 3D Co-Existence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Polarized 3D viewing systems inherently cut the viewing resolution in half, resulting in poor quality for co-existing 2D content, especially in personal computing scenarios where text is involved.
Innovation Solution
The system reformats 2D content to appear at full resolution by using a 3D content presence detector, 2D to 2D+ content modifier, and 2D+ and 3D content co-existence manager to modify 2D frames and present them as if targeted to each eye separately, enhancing the quality of 2D content while maintaining 3D content quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If polarized 3D viewing systems are used to achieve 3D content display, then 3D viewing capability is improved, but 2D content resolution deteriorates to half resolution
Solution Approach 1:
The display content is segmented into separate left-eye and right-eye views for 3D content, while 2D content is processed to create duplicate identical frames for both eyes. This segmentation allows the system to maintain full resolution for 2D content by treating it as two identical half-resolution images, whereas 3D content receives dedicated half-resolution processing for each eye.
Solution Approach 2:
Different quality processing is applied locally to different types of content: 2D content receives full resolution processing with frame duplication, while 3D content receives half resolution processing with separate left/right view generation. The system detects content type and applies appropriate processing quality to each region.
2Reliability
If polarized glasses are used for 3D content display, then left/right separation is achieved, but 2D content quality deteriorates due to half resolution per eye
Solution Approach 1:
Instead of the conventional approach where each eye receives half the resolution, the system inverts the approach for 2D content by providing each eye with a complete full-resolution image through frame duplication. This inversion maintains full resolution perception for 2D content while preserving the polarized left/right separation mechanism for 3D content.
3Adaptability or versatility
If conventional polarized 3D system displays 2D content, then 3D and 2D co-existence is achieved, but 2D content appears degraded with ghosting artifacts
Solution Approach 1:
The system changes the frame structure parameter for 2D content by duplicating identical frames for both left and right eyes, rather than splitting the image. This parameter change eliminates ghosting artifacts that occur in conventional systems where each eye receives different portions of the same 2D image, resulting in misalignment and visual artifacts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows 2D content to be displayed at full resolution alongside 3D content, significantly improving the viewing experience in mixed content scenarios without degrading the quality of 3D content.
Implementation Method 1
viewers wearing polarized glasses, with each eye lens being polarized at 45 degrees, for example, to the other or circularly polarized in opposite directions

AI summary
Polarized 3D viewing systems inherently cut the viewing resolution in half. While 3D content looks of good quality, the quality of any co-existing 2D content in windowed mode on the same screen looks poor. Embodiments may be directed to modifying the 2D content in real time and presents the enhanced 2D content (i.e. 2D+) to each eye as if it was 3D content targeted at each of the left and right eyes separately. The 2D+ content quality thus appears much better than when viewing the original 2D content on a polarized screen through polarized eyewear.
