Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual extraction of color chips is used, then flexibility in operation is maintained, but extraction errors occur and time consumption increases
Solution Approach 1:
An automatic recognition marker is introduced as an intermediary element between the color chart and the image processing system. This marker serves as a reference that enables automated identification and extraction of color chip positions, replacing manual keyboard/mouse operations while maintaining accuracy and reducing time consumption
2Ease of operation
If manual extraction operations are performed, then device complexity remains low, but operation complexity and error probability increase
Solution Approach 1:
The automatic recognition marker acts as a mediator that simplifies the operation process. Instead of manually locating and extracting each color chip, the system automatically identifies positions based on the marker, making the operation easier while significantly improving reliability by eliminating human error
3Extent of automation
If automatic recognition markers are added to the color chart, then patch recognition automation is achieved, but device complexity increases
Solution Approach 1:
The color chart is segmented into functional components: color chips for measurement and an automatic recognition marker for positioning. This segmentation allows the marker to be added as a separate element that enables automation without complicating the core color measurement functionality
Solution Approach 2:
The automatic recognition marker serves multiple functions: it provides reference for automated position detection, enables image processing algorithms to locate color chips accurately, and maintains compatibility with existing color chart structures. This multi-functionality justifies the added complexity by delivering significant automation benefits

AI summary
When relation between a color of a color chip (a patch) in a color chart and a color of a color chip in an image-captured color chart is calculated, the color chip of the image-captured color chart was manually extracted by operating a keyboard or a mouse. Such an operation had a problem that an extraction error may occur, and that it takes time to manually extract all color chips in the color chart. The present invention solved the problem by a color chart in which recognition can be easily and automatically executed. The color chart includes a plurality of patches, and an automatic recognition marker configured to automatically recognize at least one of the plurality of patches.
