Solution Overview
Problem
Existing colorimetric methods fail to accurately determine which color patches should undergo colorimetry, leading to unnecessary colorimetric processes and increased load on colorimetric apparatuses.
Innovation Solution
A colorimetric method and apparatus that acquire colorimetric values and determine whether color patches should undergo colorimetry by comparing these values with reference values, using the L*a*b* color space to identify correct quadrants and decode values, and checking color differences within predetermined ranges to differentiate between patches that should and should not be colorimetrically measured.

Engineering Contradiction Analysis
1Productivity
If colorimetry is performed on all color patches without verification, then the colorimetric apparatus processes all patches, but unnecessary colorimetric operations increase the load on the apparatus and waste time
Solution Approach 1:
The patent applies preliminary action by verifying whether color patches should undergo colorimetry before actually performing the colorimetric measurement. The determination unit checks the color patch information and reference values in advance to identify patches that should not be measured, preventing unnecessary colorimetric operations from occurring in the first place.
Solution Approach 2:
The patent extracts and separates color patches into two categories: those that should undergo colorimetry and those that should not. By identifying and excluding patches that should not be measured from the colorimetric process, the system reduces unnecessary operations while maintaining accurate measurement of relevant patches.
2Measurement precision
If colorimetry is performed on color patches that should not undergo colorimetry, then the colorimetric apparatus processes all patches, but the accuracy of colorimetric measurements is compromised and unnecessary operations increase
Solution Approach 1:
The patent implements feedback by using reference values and determination units to verify whether color patches should undergo colorimetry before measurement. The system continuously checks the color patch information against reference data and adjusts the colorimetric process accordingly, ensuring only appropriate patches are measured and improving overall measurement accuracy and reliability.
3Measurement precision
If the determination process checks all color patches thoroughly, then the accuracy of identifying correct patches is improved, but the processing load on the colorimetric apparatus increases
Solution Approach 1:
The patent applies local quality by implementing different levels of verification for different color patches. Instead of uniformly processing all patches with the same complexity, the system determines the appropriate verification level based on the specific characteristics and requirements of each color patch, reducing overall processing load while maintaining identification accuracy where needed.

AI summary
A colorimetric method includes performing colorimetry on color patches to acquire colorimetric values, and determining whether or not color patches subjected to colorimetry are color patches that should undergo colorimetry based on the colorimetric values and reference values.
