Dynamic Link Calibration for Medical Display Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical monitors struggle to maintain consistent display characteristics between images displayed from external devices and those displayed independently, leading to potential differences in image quality, especially when calibration schedules are not met.
Innovation Solution
A display apparatus and method that execute periodic single unit and link calibrations, determining if an image signal from an external apparatus is present to adjust calibration timing, ensuring that both types of images are calibrated appropriately to match target values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If link calibration is performed only during periodic calibration schedules, then calibration timing is standardized, but link calibration may not be performed when external apparatus is connected leading to display characteristic differences
Solution Approach 1:
The calibration execution unit dynamically determines whether to execute link calibration based on real-time detection of external apparatus connection status, transitioning from a static periodic calibration schedule to a dynamic calibration execution strategy that adapts to actual usage conditions
Solution Approach 2:
The system continuously monitors the connection status of external apparatus and uses this feedback information to trigger link calibration when needed, creating a closed-loop control system that maintains display characteristic consistency based on actual operational state
2Reliability
If link calibration is executed whenever external apparatus is connected, then display characteristics are maintained, but calibration operations may occur unnecessarily consuming time and resources
Solution Approach 1:
The system performs link calibration selectively rather than continuously - executing calibration only when external apparatus connection status changes or when display characteristic deviation is detected, avoiding unnecessary calibration operations while maintaining sufficient display quality
Solution Approach 2:
The calibration execution unit changes the operational parameters of the calibration process based on external apparatus connection status and display characteristic measurements, adjusting when and how calibration is performed to optimize both reliability and efficiency

Function Achieved in This Case
This approach ensures that display characteristics of images from external devices and those displayed independently on medical monitors remain consistent, preventing differences and maintaining image quality as per target values, even when calibration schedules are not adhered to.

AI summary
A display apparatus that can execute single unit calibration that is performed by displaying an image stored in the display apparatus in advance, and link calibration that is performed by displaying an image based on an image signal which is input from an external apparatus, comprises an execution unit that performs periodic calibration in which the single unit calibration and the link calibration are periodically executed and a determination unit that determines whether an image signal from the external apparatus is input or not, wherein the execution unit executes the link calibration during a period in which the determination unit determines that an image signal from the external apparatus is input, when the link calibration could not be executed during the periodic calibration.
