3D Video Signal Processor Automatic 2D Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D video display apparatuses fail to display 2D video content when a 3D video signal is received, requiring users to manually convert formats through a user input unit, and users without glasses may experience suboptimal viewing of 3D content or ghost phenomena.
Innovation Solution
A display apparatus with a video signal processor that detects the format of received video signals and automatically converts 3D signals to 2D, allowing users to select between 2D and 3D formats through a user interface, enabling direct 2D video display and optional conversion to 3D.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 3D video display apparatus displays 3D video signal when received, then 3D viewing capability is achieved, but users without glasses experience ghost phenomenon and suboptimal viewing
Solution Approach 1:
The display apparatus dynamically switches between 3D and 2D display modes based on whether glasses are detected. The system transitions from static 3D display to adaptive mode selection, detecting glass presence and automatically adjusting display format to eliminate ghost phenomenon for users without glasses.
Solution Approach 2:
The system automatically detects whether glasses are being worn and self-adjusts the display format without requiring manual user input. The apparatus serves itself by monitoring glass presence and converting between 3D and 2D modes autonomously, preventing ghost phenomenon for users without glasses.
2Adaptability or versatility
If a 3D video display apparatus requires manual format conversion through user input unit, then format flexibility is achieved, but user convenience deteriorates
Solution Approach 1:
The display apparatus automatically detects glass presence and performs format conversion without requiring manual user input through the user input unit. The system serves itself by monitoring glass presence and autonomously switching between 3D and 2D modes, maintaining format flexibility while dramatically improving user convenience.
Solution Approach 2:
The system performs automatic format conversion in advance based on glass detection, eliminating the need for users to manually convert formats. By detecting glass presence and pre-converting formats automatically, the system prepares the optimal display mode before user viewing begins.
3Ease of operation
If a display apparatus automatically converts 3D signal to 2D, then user convenience is improved, but device complexity increases
Solution Approach 1:
The display apparatus extracts format information from metadata accompanying the video signal to determine whether conversion is needed. By extracting and utilizing this existing information, the system avoids complex analysis while enabling automatic 3D-to-2D conversion based on glass presence detection.
Solution Approach 2:
The video signal processor performs multiple functions: it detects glass presence, extracts format information from metadata, determines conversion necessity, and executes format conversion. This multi-functionality consolidates complex operations into a single integrated component, managing device complexity while improving user convenience.

AI summary
An apparatus and method which display a three dimensional (3D) video signal, the apparatus comprising: a receiver which receives a video signal; a video signal processor which processes the received video signal; a display unit which displays thereon the processed video signal; and a controller which, in response to the received video signal being a 3D video signal, controls the video signal processor to convert the received 3D video signal into a two dimensional (2D) video signal, and displays the 2D video signal on the display unit.
