Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional stereoscopic image display apparatuses fail to provide a universally acceptable stereoscopic perspective as different observers perceive the same 3D content differently, making it difficult to display an image that feels adequate to all viewers.

Innovation Solution

A display apparatus and method that includes an image processing system which enhances or adjusts the stereoscopic perspective based on observer settings by analyzing the subject distance in images and adjusting the blue component ratio or blurring to create a more pronounced depth effect, allowing for customizable stereoscopic experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional stereoscopic image display apparatus displays the same 3D content, then the image is displayed with a fixed stereoscopic perspective, but different observers perceive different stereoscopic perspectives making it difficult to provide a universally adequate image

Engineering Contradiction:

Improveadaptability to different observer preferencesVSAvoidcomplexity of image processing system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display apparatus dynamically adjusts the stereoscopic perspective enhancement amount based on individual observer settings. The image processing section modifies the enhancement level in real-time according to observer characteristics, transforming a static display system into an adaptive one that accommodates different perception preferences without requiring complete system redesign

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the enhancement amount parameter of the stereoscopic perspective based on observer settings. By adjusting this specific parameter rather than overhauling the entire image processing pipeline, the system achieves adaptability while maintaining relatively simple device architecture

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If the stereoscopic perspective enhancement amount is increased to provide stronger depth effect, then the perceived depth is enhanced, but the image's contour or structural outline may be altered

Engineering Contradiction:

Improveprecision of stereoscopic perspective enhancementVSAvoidintegrity of image contour and structure

Core Design Contradiction:

Manufacturing precisionVSShape

Solution Approach 1:

The image processing section applies stereoscopic perspective enhancement selectively to specific regions of the image based on subject distance. By adjusting the enhancement amount according to local depth information rather than uniformly across the entire image, the system enhances perceived depth while preserving the overall contour and structural integrity of the image

Inventive Principle:

Principle #3Local quality

AI summary

A display apparatus includes a display section and a changing section. The display section displays an image that gives a stereoscopic perspective to an observer. The changing section changes an amount by which the stereoscopic perspective in the image displayed by the display section is enhanced according to a setting of the observer.
