Display System Brightness Simulation for Projection Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods fail to accurately simulate the visibility of a projection image, as the visibility is not solely determined by the brightness of the projection image, making it difficult for users to envision the actual visibility when viewing a simulation image.
Innovation Solution
A display method and system that superimpose a display image onto a target image, adjusting the brightness of both based on specific information to simulate the projection image's visibility, including the target region and display image brightness, using a camera, display, and processor to create a realistic simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the brightness of the projection image is adjusted to simulate visibility, then the simulation accuracy improves, but the complexity of the display system increases
Solution Approach 1:
The patent segments the display image into multiple layers: a target image layer showing the background scene and a display image layer showing the projection content. Each layer can be independently adjusted in brightness, allowing precise control over the simulated visibility without requiring a completely complex system redesign.
Solution Approach 2:
The patent implements dynamic brightness adjustment where the brightness of the target image and display image can be independently modified based on input information. This allows the system to adapt the simulation to different lighting conditions and projection scenarios, improving accuracy while maintaining manageable complexity through software-based control.
2Measurement precision
If the brightness of the target region and display image are independently adjusted, then the visibility simulation accuracy improves, but the operation complexity increases
Solution Approach 1:
The patent uses feedback mechanisms where the processor receives input information about the actual brightness of the target region and the projection image, then automatically adjusts the brightness of the corresponding image layers. This feedback loop simplifies operation for the user while maintaining high simulation accuracy.
Solution Approach 2:
The system performs self-adjustment by automatically modifying the brightness of the target image and display image based on received information about actual lighting conditions. This eliminates the need for manual brightness adjustment by the user, improving ease of operation while maintaining accuracy.
