Master-Slave Display Apparatus Centralized Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-projection systems, individual projectors must perform image processing on the entire image, leading to usability issues and increased processing burden, as image information is directly supplied from the head projector to downstream projectors without centralized control.
Innovation Solution
A display apparatus with a master and slave mode configuration, where a master projector performs image processing on combined image information and outputs it to downstream projectors, reducing the need for each projector to perform extensive image processing and allowing centralized image quality correction, thereby reducing processing burdens and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image information is directly supplied from head projector to downstream projectors without centralized processing, then each projector can independently process and display images, but the processing burden increases for each projector and image quality correction becomes difficult to manage
Solution Approach 1:
The patent introduces a master projector as an intermediary that performs centralized image processing on the entire image before distributing processed image information to downstream projectors. This mediator approach resolves the contradiction by centralizing the complex processing tasks in one unit while allowing downstream projectors to simply display their assigned portions, thereby improving ease of operation for image quality correction while reducing the processing burden on each individual projector.
2Reliability
If each projector individually performs image processing on the entire image, then each projector has full control over image processing, but the processing load increases and usability decreases
Solution Approach 1:
The patent applies segmentation by dividing the image processing tasks: the master projector performs centralized processing on the entire image to ensure quality and control, while downstream projectors are segmented to handle only their specific display portions. This segmentation maintains reliable image processing control through centralized management while improving overall processing efficiency by eliminating redundant processing across multiple projectors.
3Manufacturing precision
If multiple projectors perform extensive image processing, then image quality can be corrected at each projector, but the processing time and computational resources increase significantly
Solution Approach 1:
The master projector performs preliminary image processing on the entire image before distribution to downstream projectors. This preliminary action ensures that image quality correction is completed in advance, allowing downstream projectors to receive pre-processed image information that requires minimal additional processing. This approach maintains high image quality while significantly reducing the processing time required at each projector.
