Solution Overview

Problem

The subjective image quality of 3D display images is compromised due to the accuracy of three-dimensional shape data used for rendering, particularly when vertex reduction is necessary to manage data load and transmission efficiency.

Innovation Solution

An information processing system that includes a distribution server and a display control apparatus, which generate and transmit data sets containing three-dimensional shape data and stereo texture data, allowing for vertex reduction while maintaining image quality by using left-eye and right-eye texture data to render images, thus adapting to load information regarding transmission path bandwidth and processing performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If three-dimensional shape data with high accuracy is used for rendering, then the subjective image quality of the display image is improved, but the data load and transmission requirements increase

Engineering Contradiction:
Improveaccuracy of three-dimensional shape dataVSAvoiddata load
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent segments the texture data into left-eye texture data and right-eye texture data separately, allowing independent optimization for each eye's viewing requirements. This segmentation enables the system to use lower-resolution texture data for one eye while maintaining higher quality for the other, thereby reducing overall data load while preserving subjective image quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different texture resolutions to different regions of the display based on local quality requirements. By associating left-eye and right-eye texture data with the three-dimensional shape data, the system can selectively apply higher resolution only where needed (e.g., for regions with complex geometry or important visual features) while using lower resolution for simpler regions, thus balancing data load and image quality.

Inventive Principle:
Principle #3Local quality

2Productivity

If vertex reduction is performed on three-dimensional shape data to manage data load, then transmission efficiency is improved, but the accuracy of the three-dimensional shape data decreases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidaccuracy of three-dimensional shape data
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary action by pre-processing the three-dimensional shape data to associate it with corresponding left-eye and right-eye texture data before transmission. This preliminary association allows the rendering device to efficiently reconstruct the 3D scene using reduced vertex data while compensating for the loss of geometric detail through the accompanying texture information, thus maintaining transmission efficiency without significant quality degradation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces texture data as an intermediary element that mediates between the reduced three-dimensional shape data and the final display image. The texture data acts as a compensator that fills in the gaps created by vertex reduction, allowing the system to achieve both low data load and acceptable image quality by having the texture information compensate for the simplified geometry.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If stereo texture data is used to maintain image quality, then the stereoscopic effect is improved, but the data load increases

Engineering Contradiction:
Improvesubjective image qualityVSAvoiddata load
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies dynamics by making the texture data selection adaptive rather than static. The system dynamically adjusts which texture data to transmit and at what resolution based on the current viewing conditions, device capabilities, and network bandwidth. This dynamic approach allows the system to maximize image quality when possible while minimizing data load when constraints require it, thereby achieving both goals flexibly.

Inventive Principle:
Principle #15Dynamics
