Video Image Deflection for Off-Center Viewing in Multimedia Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia devices suffer from a poor display effect when users are not directly in front of the center point of the display area, as the viewing experience deteriorates with increasing angle from the center, with no effective solution in existing technologies to address this issue.
Innovation Solution
A video image display method that acquires a target image, determines the spatial positional data of left and right eye objects relative to the multimedia device, calculates a deflection coefficient based on this data, and deflects the video image accordingly to ensure it is directly facing the user, thereby improving the display effect by making the image appear to follow the user's gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user views the display from positions other than the center point, then the viewing flexibility and comfort are improved, but the display quality and viewing effect deteriorate
Solution Approach 1:
The patent applies dynamics by making the displayed image movable rather than fixed. The system dynamically adjusts the image position and orientation based on real-time detection of user eye position, allowing the image to follow the user's gaze and maintain optimal viewing quality regardless of the user's position relative to the display center
Solution Approach 2:
The patent implements feedback by using eye position detection to continuously monitor user viewing position and automatically adjusting the displayed image accordingly. The system detects eye position, calculates the appropriate transformation, and applies real-time adjustments to maintain display quality across different viewing angles
2Device complexity
If the display image is fixed at the center, then the display structure is simple, but the viewing effect deteriorates when users are not at the center position
Solution Approach 1:
The system uses eye position detection to provide feedback on user location, automatically adjusting the displayed image to follow the user's gaze. This feedback mechanism enables the simple display structure to achieve superior viewing effects across multiple positions without complex hardware modifications
Solution Approach 2:
The patent replaces complex mechanical adjustment systems with software-based image transformation. Instead of physically moving display components, the system uses digital image processing to deflect and reposition the displayed content, achieving adaptive viewing with minimal hardware complexity
3Manufacturing precision
If the image is deflected according to eye position data, then the viewing effect is improved, but the processing complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with software-based image transformation. Instead of physically moving display components, the system uses digital image processing to deflect and reposition the displayed content, achieving adaptive viewing with minimal hardware complexity
Solution Approach 2:
The system changes image display parameters (position, orientation, scale) based on detected eye position data. By dynamically adjusting these parameters through software, the system achieves improved viewing effects without adding physical complexity to the display hardware
