Dynamic Patch Display for Accurate Light Output Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing software and display devices face challenges in measuring the physical property values of light output from color patches, as they often cannot change the display position of color patches or adjust the measurable area of sensors, making it difficult to verify if images represented by CMYK values are displayed in their original colors.
Innovation Solution
A measurement method that displays a patch image based on pixel values at target coordinates on a display screen at different coordinates and measures the physical property values of light output from these patches, allowing for accurate verification of luminance and chromaticity corresponding to CMYK values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color patches are displayed at fixed positions in image processing software, then the software can generate and display color patches corresponding to specific CMYK values, but the display position of color patches cannot be changed by external control
Solution Approach 1:
The patent implements dynamic positioning of color patches by allowing the display coordinates to be changed through external control. The measurement device can specify target coordinates on the display screen, and the system dynamically adjusts which color patch is displayed at those coordinates, transforming a static display system into a dynamic one that adapts to measurement requirements.
2Adaptability or versatility
If sensors are provided with fixed measurement areas, then the sensor can measure physical property values from specific regions, but the measurable area cannot be changed
Solution Approach 1:
The patent implements dynamic measurement area selection by allowing the measurement device to specify target coordinates where color patches should be displayed. This enables the measurement area to be dynamically adjusted to match the position of color patches generated by image processing software, transforming a fixed measurement system into a flexible one that adapts to different measurement scenarios.
3Measurement precision
If the physical property value of light output from color patches cannot be measured due to position mismatch, then verification of original color display becomes impossible, but adding measurement capability increases system complexity
Solution Approach 1:
The patent introduces an intermediary mechanism where the measurement device communicates with the display device to coordinate color patch display positions and measurement targets. This intermediary coordination allows the measurement system to accurately capture physical property values from color patches without requiring complex integrated hardware, solving the verification problem through coordinated control.
