Solution Overview

Problem

Existing 3D video processing methods lack comprehensive visual information for adjusting depth settings, leading to visual fatigue and incomplete representation of 3D effects, as users struggle to adapt disparity levels to their individual preferences.

Innovation Solution

A method for displaying a 3D graphical settings menu that allows users to dynamically adjust image depth through a multimedia terminal, using a 3D graphical element with incremental depth settings, enabling users to preview and apply depth modifications interactively, with interpolation techniques to generate new images based on selected disparity values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a traditional 2D settings menu is used for depth adjustment, then the device complexity is reduced, but the visual information completeness for representing 3D effects is insufficient

Engineering Contradiction:

Improvevisual information completenessVSAvoidmenu structure complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The settings menu is transformed from a traditional 2D interface into a 3D graphical element that exists within the stereoscopic space. This 3D menu contains incremental depth settings that visually represent minimum and maximum depth values, allowing users to comprehend the overall amplitude of 3D effects through spatial positioning rather than abstract 2D controls.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If the disparity amplitude is increased to enhance 3D effects, then the visual impact is improved, but visual fatigue increases for some spectators

Engineering Contradiction:

Improve3D effect intensityVSAvoidvisual fatigue

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The 3D settings menu provides visual feedback by displaying the positional relationship between the menu element and the image foreground. This feedback mechanism allows spectators to understand the current depth settings and adjust them to comfortable levels, enabling adaptation to individual visual tolerance and reducing visual fatigue while maintaining desired 3D effect intensity.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the disparity is fixed by the director, then the production process is simplified, but the adaptability to individual viewer preferences is reduced

Engineering Contradiction:

Improvedepth setting adaptabilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The settings menu is designed as a dynamic 3D graphical element that can be moved along the vertical direction within the image space. Users can interactively adjust the menu position to modify depth settings, transforming the fixed director-defined disparity into a dynamic, user-adaptable configuration that maintains operational simplicity through intuitive spatial interaction.

Inventive Principle:

Principle #15Dynamics

AI summary

The invention relates to a method for displaying a settings menu. In order to optimize the graphical representation of setting carried out by a spectator, the method comprises steps for: - displaying said settings menu comprising a three-dimensional graphical element (20) of which one of the dimensions extends according to a depth direction (z), - displaying, on said graphical element, of at least one setting (203, 204, 205) representative of at least one item of depth information.
