Solution Overview

Problem

Current 3D rendering technologies are limited to horizontal disparity evaluation, resulting in unsatisfactory 3D effects when the viewer's eyes axis is not horizontal, as they only perform horizontal view interpolation.

Innovation Solution

A method that determines a rendered tridimensional content by considering the viewer's eyes orientation relative to a display device's reference axis, allowing for adaptation of the 3D vision by calculating or selecting a rendered view based on the viewer's orientation, disparity direction, and occlusion information, which can include depth maps and light-field data, to provide a more immersive 3D experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If horizontal view interpolation is performed using traditional 3D camera rigs, then the processing method is simple and only horizontal disparity can be evaluated, but the 3D effect becomes unsatisfactory when the viewer's eyes axis is not horizontal

Engineering Contradiction:
Improve3D effect quality for various eye orientationsVSAvoidview interpolation processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the view interpolation process adaptive to the viewer's eye orientation. Instead of using fixed horizontal interpolation, the system dynamically adjusts the interpolation direction and parameters based on real-time detection of the viewer's gaze direction, allowing the 3D rendering to adapt to various viewing angles while maintaining computational efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the interpolation parameters dynamically based on the viewer's eye orientation. By modifying the interpolation direction vector and disparity parameters according to the detected gaze angle, the system achieves high-quality 3D rendering for non-horizontal viewing angles without requiring complex reconfiguration of the entire rendering pipeline

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If multiple reference views are used to improve interpolation quality, then the 3D rendering accuracy improves, but the computing complexity and data processing load increase

Engineering Contradiction:
Improverendered view accuracyVSAvoidcomputing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by using a single reference view but adapting the interpolation process locally to match the viewer's specific eye orientation. Instead of requiring multiple reference views for different directions, the system adjusts the interpolation parameters locally for each pixel based on the viewer's gaze direction, achieving high accuracy without the computational burden of processing multiple reference views

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses a single reference view as a template and creates synthesized views by copying and transforming the reference image data according to the viewer's eye orientation. The system generates virtual camera views by warping and interpolating the reference view according to calculated disparity parameters, avoiding the need to store and process multiple actual reference views

Inventive Principle:
Principle #26Copying

3Manufacturing precision

If occlusion information is added to the reference content, then the rendered view quality improves, but the amount of data to be processed increases

Engineering Contradiction:
Improverendered content qualityVSAvoiddata quantity
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies partial action by selectively using occlusion information only where needed during the interpolation process. Instead of processing and storing complete occlusion data for the entire scene, the system extracts and applies occlusion masks only for the specific regions and viewing angles required for the current rendered view, reducing data processing load while maintaining rendering quality

Inventive Principle:
Principle #16Partial or excessive action
