Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for colorimetry on a color chart are cumbersome, requiring frequent replacement of input devices with spectrophotometers, leading to low usability.
Innovation Solution
A method for controlling an information processing apparatus that involves acquiring reference values and patch layout information, performing colorimetry using a spectrophotometer, and automatically determining the row of the color chart on which the user has performed colorimetry based on the acquired values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of rows is required using input devices, then measurement precision can be controlled, but device complexity and ease of operation deteriorate due to frequent replacement of input devices with spectrophotometers
Solution Approach 1:
The system automatically determines which row requires colorimetry based on the color chart layout and patch positions, eliminating the need for manual row selection. The spectrophotometer automatically identifies and measures the correct row without requiring user intervention to select or re-select rows, making the system self-serve the measurement process.
Solution Approach 2:
The control apparatus acts as an intermediary between the user and the spectrophotometer. It receives color chart information, determines the target row automatically, and controls the spectrophotometer to measure the correct row without requiring the user to manually select or replace input devices.
2Adaptability or versatility
If frequent replacement of input devices occurs, then adaptability to different rows can be achieved, but ease of operation deteriorates due to cumbersome procedures
Solution Approach 1:
The control apparatus performs preliminary determination of the target row based on color chart layout information before the spectrophotometer measurement begins. This pre-calculation eliminates the need for frequent device replacement or re-selection during the measurement process, as the correct row is already identified and locked in.
3Measurement precision
If manual row selection is performed, then measurement precision is maintained, but loss of time increases due to repeated device replacement
Solution Approach 1:
The control apparatus uses feedback from the color chart layout information to automatically determine the target row. By continuously referring to the pre-stored layout data and comparing it with the current measurement position, the system maintains measurement precision while eliminating time-consuming manual selection and device replacement steps.

AI summary
A method of controlling an information processing apparatus includes acquiring reference values of patches of a color chart and information on layout of the patches, acquiring colorimetric values obtained by performing colorimetry on the color chart by a spectrophotometer, and specifying a row of the color chart on which a user has performed colorimetry based on the acquired reference values of the patches, the acquired information on the layout of the patches, and the acquired colorimetric values.
