Engineering Contradiction Analysis
1Area of stationary object
If multiple projectors are used for projection splicing, then the coverage area is increased, but brightness unevenness and color inconsistency occur in the overlapping area
Solution Approach 1:
The patent applies local quality by implementing different processing strategies for overlapping and non-overlapping areas. The system identifies overlapping regions and applies brightness reduction and color correction specifically to these areas, while leaving non-overlapping areas unchanged. This localized processing ensures uniformity at the boundaries where projectors meet without affecting the overall image quality.
Solution Approach 2:
The system changes parameters (brightness and color) dynamically based on the spatial position of pixels. By detecting whether a pixel belongs to an overlapping area, the system adjusts its brightness and color parameters accordingly, creating a smooth transition between projected images and eliminating visible seams or color mismatches.
2Manufacturing precision
If current black level adjustment technology is used, then color adjustment is possible, but the adjustment process becomes tedious and complex
Solution Approach 1:
The system performs self-service by automatically detecting overlapping areas and calculating the necessary brightness and color corrections without requiring manual user input. The processing device autonomously identifies the geometry of projection overlaps and applies appropriate corrections, eliminating the need for users to manually define adjustment parameters.
Solution Approach 2:
The system implements feedback by continuously monitoring the projected image and adjusting brightness and color parameters based on detected overlapping regions. The processing device analyzes the actual projection output and makes real-time corrections to achieve uniform appearance across all projectors.
3Ease of operation
If user directly views projected image for adjustment, then simple interface is provided, but integrated view of multiple projectors and their interactive relationship is lost
Solution Approach 1:
The patent transitions from two-dimensional projected image viewing to three-dimensional spatial understanding by displaying virtual projector models and their spatial relationships on a computer screen. This additional dimensional representation allows users to comprehend the interactive relationships between multiple projectors while maintaining an intuitive interface through graphical visualization.
