Solution Overview

Problem

Current naked-eye 3D display technologies require extra TV resources for viewpoint conversion, leading to reduced image definition and inefficient use of resources.

Innovation Solution

A method and system that decodes 3D signals, separates and improves images, estimates depth information, and interpolates viewpoints to create a composite image, which is then calibrated and transmitted for high-definition naked-eye 3D display, utilizing signal processing techniques like luminance partition scaling and hierarchical interpolation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If viewpoint conversion is performed using conventional methods, then multiple viewpoints can be generated for naked-eye 3D display, but extra TV resources are consumed and image definition is reduced

Engineering Contradiction:
Improveviewpoint conversion capabilityVSAvoidimage definition
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments the image processing into distinct modules: depth extraction module, viewpoint estimation module, and image synthesis module. Each module handles specific tasks independently, allowing efficient resource utilization while maintaining high image definition through specialized processing for each function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes processing parameters by using depth information as a key parameter to control viewpoint synthesis. By adjusting depth maps and using them to guide pixel displacement and blending operations, the system achieves high-definition multi-viewpoint generation without excessive resource consumption.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If viewpoint conversion is performed using conventional methods, then multiple viewpoints can be generated for naked-eye 3D display, but TV resources are used inefficiently

Engineering Contradiction:
Improveviewpoint conversion capabilityVSAvoidresource utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent performs preliminary depth extraction and analysis before viewpoint synthesis. By pre-processing the image to obtain accurate depth maps and identifying key objects, the system prepares data structures that facilitate efficient viewpoint conversion, reducing computational overhead during the actual synthesis process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses depth information to create virtual copies of objects at different positions for multiple viewpoints. Instead of processing entire images for each viewpoint, it selectively copies and relocates object pixels based on depth data, significantly reducing computational resources while maintaining image quality.

Inventive Principle:
Principle #26Copying
