Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to efficiently store and reproduce 3D image data from multiple cameras across various devices due to the lack of a defined file structure for 3D image data and related parameters, leading to compatibility issues and visual fatigue.
Innovation Solution
A mobile terminal apparatus and method that includes a camera unit and a 3D data manager to obtain, compress, and generate 3D data as a single file, analyzing 3D parameters to reproduce the data and provide a 3D effect, while reducing visual fatigue by processing boundary occlusion regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate image files are stored for 3D data from multiple cameras, then the 3D effect can be provided, but the compatibility and reliability of content sharing between devices deteriorates due to lack of defined file structure
Solution Approach 1:
The patent merges multiple separate image files from different cameras into a single integrated 3D image file. The file structure combines multiple image data portions (first image data from first camera, second image data from second camera) along with 3D parameter information into one unified file, eliminating the need for multiple separate files and ensuring compatibility across devices.
Solution Approach 2:
The patent creates a universal 3D image file structure that can be reproduced across various types of devices (mobile terminals, 3D TVs, PCs). The standardized file format includes all necessary components (multiple image data portions, 3D parameters, metadata) in a single file that any compliant device can interpret and reproduce, making the content universally compatible.
2Ease of operation
If all 3D image data and parameters are stored in one file, then the ease of operation and content sharing improves, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent segments the 3D image file into distinct functional portions: first image data portion, second image data portion, 3D parameter information, and metadata. Each segment serves a specific purpose and can be independently processed or extracted, reducing the overall processing complexity while maintaining the benefits of a unified file structure.
Solution Approach 2:
The patent incorporates 3D parameter information that describes the shooting conditions (camera positions, angles, distances) as structured data within the file. These parameters enable receiving devices to automatically adjust reproduction settings without complex manual configuration, simplifying operation while managing data complexity through standardized parameter formats.
3Loss of information
If boundary occlusion regions are included in 3D reproduction, then the completeness of visual information is maintained, but visual fatigue increases
Solution Approach 1:
The patent applies different processing quality to different regions of the 3D image. Boundary occlusion regions (areas visible in one camera's view but not the other) are identified and processed differently from central regions. The system can selectively adjust or mask these boundary areas to reduce visual fatigue while preserving the essential 3D effect and majority of visual information.
