Terminal Device Color Display Control for Measurement Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using a colorimeter with a separate display section and a computer screen, users may mistakenly operate the colorimeter due to differences in color reproducibility between the two displays, leading to incorrect color measurements.
Innovation Solution
A terminal device and colorimeter system that determines whether to display a color measurement result on both the terminal display section and the colorimeter display section or only on the terminal display section based on the distance between them, ensuring the user views the measurement result on the display with higher color reproducibility to avoid mistakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the color measurement result is displayed on both the colorimeter display section and the terminal display section, then user convenience is improved, but color measurement accuracy deteriorates due to different color reproducibilities
Solution Approach 1:
The patent implements dynamic control of the display system by detecting the distance between the terminal device and colorimeter. When the distance is within a threshold (indicating the user is close and can see both displays), the system prohibits color display on the colorimeter display section. When the distance exceeds the threshold, the system permits color display on the colorimeter display section. This dynamic adjustment resolves the contradiction by adapting the display behavior to the actual usage scenario.
2Measurement precision
If the color measurement result is displayed only on the terminal display section, then color measurement accuracy is improved, but user convenience deteriorates
Solution Approach 1:
The system dynamically switches between single-display and dual-display modes based on distance detection. When the terminal device is far from the colorimeter, the system permits color display on the colorimeter display section, providing dual-display convenience. When the terminal device is close, the system prohibits color display on the colorimeter display section, ensuring accurate color reference on the terminal display. This dynamic behavior resolves the contradiction by providing the appropriate display mode for each situation.
3Adaptability or versatility
If the color measurement result is displayed on the colorimeter display section, then device independence is improved, but operation reliability deteriorates due to potential user mistakes
Solution Approach 1:
The system performs preliminary anti-action by proactively prohibiting color display on the colorimeter display section when the terminal device is detected to be close (within threshold distance). This preventive measure stops the potential harmful action (user mistake due to color reproduction differences) before it can occur. By detecting the risky scenario in advance and blocking the problematic display behavior, the system maintains operation reliability while preserving device independence functionality.

AI summary
A terminal device includes a communication section configured to communicate with a colorimeter including a colorimeter display section, and a processing section configured to perform display processing on a terminal display section, wherein the processing section performs determination processing as to whether to display a color of a color measurement result produced by the colorimeter both on the colorimeter display section and the terminal display section or display the color only on the terminal display section based on a distance from the colorimeter.
