Multi-Projector Synchronization via Master Mediator Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-projection systems, synchronizing image quality adjustments across multiple projectors is challenging, leading to unnatural composite screens and increased costs due to network management requirements.
Innovation Solution
A projection apparatus with a holding unit for setting information, a reception unit for menu screen instructions, a determination unit to decide on menu display based on settings, and a projection unit to project the menu screen, allowing for synchronized adjustments without network interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If network cables and interfaces are added to transmit operation contents between projectors, then synchronized operation control is achieved, but device complexity and cost increase
Solution Approach 1:
The master projector serves as an intermediary device that receives operation inputs and distributes them to slave projectors. Instead of requiring direct network connections between all projectors, the master projector mediates the control signal distribution, simplifying the overall system architecture while achieving synchronized operation control across all projectors in the multi-projection system
Solution Approach 2:
The master projector performs multiple functions: it acts as both a regular projector displaying content and as a control distribution hub for the entire multi-projection system. By integrating control signal processing and distribution capabilities into the master projector, the system achieves synchronized operation without requiring additional dedicated control hardware at each projector location
2Extent of automation
If network management functionality is added to all projectors, then operation synchronization is enabled, but installation and management complexity increase
Solution Approach 1:
The control functionality is segmented and concentrated in the master projector rather than being distributed to all projectors. This segmentation allows the complex network management and operation synchronization tasks to be handled by a single device, reducing the installation and management burden on individual projectors while still achieving system-wide synchronization
3Manufacturing precision
If image quality adjustment is made to only one projector, then that projector's image quality is improved, but the composite screen becomes unnatural due to inconsistency
Solution Approach 1:
The system implements feedback by displaying adjustment confirmation screens on all slave projectors that reflect the image quality adjustments made on the master projector. This visual feedback mechanism allows operators to verify that adjustments are being applied consistently across all projectors, ensuring the composite screen maintains natural consistency while benefiting from improved image quality
