Solution Overview

Problem

Current 3D video processing technologies often result in reduced resolution when displaying 3D imagery on televisions, leading to a need for improved image and video processing methods to achieve high-quality 3D rendering without significant resolution loss.

Innovation Solution

The system and methods for 3D rendering involve creating expanded 3D image frames from left and right eye sub-frames using techniques such as pixel row splicing and weighted estimation, which can retain or improve resolution, particularly by inserting new pixels between original pixel columns or rows and using inverted pixel strips to correct for resolution loss in passive 3D technologies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional 3D video processing methods are used to generate 3D imagery, then 3D display functionality is achieved, but resolution is significantly reduced

Engineering Contradiction:
Improveimage resolutionVSAvoid3D rendering capability
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent segments the 3D image processing into distinct components: left eye sub-frame, right eye sub-frame, and intermediate inverted frame. By dividing the full-resolution image into these segments and processing them separately through splicing and inversion operations, the system maintains resolution while enabling 3D rendering capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediate inverted frame as an additional dimensional element in the processing pipeline. This intermediate frame serves as a bridge between the left and right eye sub-frames, allowing resolution enhancement through weighted combination of multiple frames rather than direct manipulation of single sub-frames.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If pixel rows are spliced to create 3D sub-frames, then 3D format compatibility is achieved, but resolution loss occurs

Engineering Contradiction:
Improve3D format compatibilityVSAvoidimage resolution
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies inversion to the right eye sub-frame by reversing the order of pixel rows. This inverted frame is then combined with the left eye sub-frame using weighted averaging, where pixels from both frames contribute to the final high-resolution output. This inversion technique allows the system to recover resolution information that would otherwise be lost in conventional splicing methods.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the processing parameter from simple splicing to weighted combination with inversion. Instead of directly concatenating pixel rows from left and right sub-frames, the system applies weights to pixels from both the original and inverted frames, dynamically adjusting the contribution of each pixel to maximize resolution recovery while maintaining 3D format compatibility.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If conventional algorithms are used for 3D rendering, then processing speed is maintained, but image quality deteriorates

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent performs preliminary inversion of the right eye sub-frame before the final combination step. By pre-processing the right sub-frame through inversion and preparing the weighted combination factors in advance, the system reduces computational complexity during the final rendering stage, thereby maintaining processing efficiency while significantly improving image quality through the enhanced combination algorithm.

Inventive Principle:
Principle #10Preliminary action
