Projector Color Adjustment Synchronization via Master-Slave Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems face complexity in synchronizing the adjustment of display states across multiple projectors, leading to potential degradation in image quality due to differences in display settings, which complicates the setting process and requires manual operation of all projectors for adjustments.
Innovation Solution
An image display apparatus with a communication section that allows for the transmission of control information for synchronized adjustments, including a schedule generation section to coordinate adjustments based on accepted operations, ensuring all projectors perform adjustments according to a common schedule, thereby simplifying the operation and maintaining image uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustment operations are performed manually on each image display apparatus, then the display state can be adjusted, but the operation becomes complicated and time-consuming
Solution Approach 1:
The system copies the schedule information from one master image display apparatus to other slave image display apparatuses through communication. This allows the adjustment schedule set on one device to be automatically replicated across multiple devices, eliminating the need for manual configuration on each device and significantly reducing operation complexity and time
Solution Approach 2:
The communication section acts as an intermediary that transmits control information and schedule data between image display apparatuses. This mediator enables centralized control where one apparatus can manage and coordinate adjustments across the entire system without requiring direct manual intervention on each device
2Reliability
If schedule information is set separately on each image display apparatus, then each device can operate independently, but the setting task becomes complicated and synchronization is difficult
Solution Approach 1:
The system merges the schedule management function into a centralized system where one master apparatus holds and manages the master schedule information. This consolidated approach ensures all image display apparatuses operate from the same synchronized schedule, maintaining display consistency while greatly simplifying the setting process compared to independent configuration on each device
Solution Approach 2:
Schedule information is copied from the master apparatus to slave apparatuses through the communication section. This copying mechanism ensures all devices receive identical synchronized schedule data, guaranteeing consistent operation across the system without requiring complex independent setting procedures
3Ease of operation
If adjustment is performed on only part of the image display apparatuses, then operation is simplified, but image quality degrades due to display state differences
Solution Approach 1:
The control system is designed with universal applicability where the master schedule information can be transmitted to and executed by multiple slave image display apparatuses simultaneously. This multi-functional capability ensures that adjustments are applied uniformly across all devices in the system, maintaining image quality consistency while keeping operation simple through centralized control

AI summary
A projector includes an image projection section that displays an image based on image information, a communication section that communicates with another projector, an input operation section that accepts operation for executing a light source color adjustment process, a light source color adjustment section that executes the light source color adjustment process based on the operation accepted by the input operation section, and a control section that causes the communication section to transmit, based on the operation accepted by the input operation section, control information that causes the other projector to perform the light source color adjustment process to the other projector.
