Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic display apparatuses lack variety in expression forms, limiting their ability to effectively display multiple videos with uniform and flexible operations, especially with the increasing demand for diverse video content.
Innovation Solution
A video display apparatus that receives multiple videos and controls their display in a multi-window format, determining window projecting amounts to create varying levels of projection and recession using parallax, allowing for adaptive 2D or 3D display based on video attributes, categories, and user instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If uniform conversion of selected image to stereoscopic format is applied, then the selected image becomes conspicuous and visibility is improved, but the expression forms become limited and variety is reduced
Solution Approach 1:
The patent applies different projection amounts to different windows based on their spatial positions and content attributes. Each window is assigned a specific projection amount (positive for protruding, negative for recessing) rather than uniform treatment, enabling diverse expression forms while maintaining visibility. This local differentiation resolves the contradiction by allowing both conspicuous display and varied expression.
Solution Approach 2:
The system dynamically adjusts projection amounts based on window attributes, content types, and user settings. The projection amounts can be changed during operation according to different display scenarios, making the system adaptable. This dynamic adjustment enables the same display hardware to present multiple expression forms (2D, 3D protruding, 3D recessing) without physical reconfiguration.
2Adaptability or versatility
If multi-window format with varying projection amounts is implemented, then variety of expression forms is improved, but display complexity increases
Solution Approach 1:
The display is segmented into multiple independent windows, each capable of having its own projection amount. This segmentation allows complex multi-expression display to be managed through simple individual window controls. Each window's projection can be adjusted independently without affecting others, simplifying the overall control architecture despite the complexity of the display output.
Solution Approach 2:
The system changes display parameters (projection amounts) based on window attributes and content characteristics rather than requiring complex hardware reconfiguration. By adjusting parameters such as projection amount, window position, and size through software control, the system achieves diverse expression forms without proportionally increasing physical device complexity.
3Adaptability or versatility
If flexible display based on flexible operation is provided, then adaptability is improved, but operation complexity increases
Solution Approach 1:
The system automatically determines projection amounts and display configurations based on window attributes, content types, and pre-set rules rather than requiring manual configuration for each scenario. The display apparatus self-adjusts to create appropriate expression forms, reducing the operational burden on users while maintaining high adaptability.
Solution Approach 2:
A single display apparatus performs multiple functions (2D display, 3D protruding display, 3D recessing display) through software-based projection amount adjustment rather than requiring separate hardware systems. This multi-functionality is achieved through a universal control mechanism that handles diverse display scenarios, improving adaptability without proportionally increasing operation complexity.

AI summary
A video display apparatus includes: a receiving unit which receives plural videos; a display unit; and a control unit which controls display of the display unit such that the plural videos appear on the display unit in a multi-window format for displaying the plural videos, wherein for each of the plural windows, the control unit determines a window projecting amount indicating an amount of projection of the window, and controls the display such that a video to be displayed in the window appears to be projecting or receding, due to parallax, by an amount obtained by adding the window projecting amount to a video projecting amount indicating an amount of projection of the video.
