Color Measurement Row Detection for Repeated Color Charts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color measurement methods require users to manually switch between input devices, impairing usability when determining the correct row for color measurement on color charts with identical patches, especially when multiple rows are present.
Innovation Solution
An information processing apparatus and system that utilize colorimetric values and additional information to automatically determine the measured row, allowing for seamless color measurement without manual row selection when patches are identical across rows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic row determination is performed using only colorimetric values, then user convenience is improved, but it becomes impossible to specify the correct row when identical color patches are arranged in multiple rows
Solution Approach 1:
The patent introduces a new dimension of information (row identification information such as position data, timing data, or external identifiers) beyond the traditional colorimetric values to uniquely identify rows. This dimensional expansion allows the system to distinguish between identical color patches in different rows, resolving the ambiguity that prevents automatic row determination when patches are repeated across multiple rows.
2Measurement precision
If manual row selection using input apparatus is required, then row specification accuracy is improved, but ease of operation deteriorates due to hand switching between devices
Solution Approach 1:
The system performs self-service by automatically determining the measured row through colorimetric analysis and row identification information without requiring manual intervention. The apparatus autonomously matches measured color data with stored reference data, identifies the corresponding row, and proceeds with color management operations, thereby eliminating the need for users to manually select rows using input devices like mice or keyboards.
3Reliability
If color measurement is performed on color charts with identical patches in multiple rows, then measurement completeness is improved, but automatic row determination becomes difficult
Solution Approach 1:
The patent introduces row identification information as an intermediary element that mediates between the colorimetric measurements and the row specification. This intermediary data (such as positional coordinates, timing stamps, or external identifiers associated with each row) bridges the gap between identical color patches and their unique row locations, enabling the system to maintain measurement completeness across all rows while simplifying the determination process through automatic matching.

AI summary
An information processing apparatus performs, as a first specification processing, specification processing of specifying, in a color chart composed of a plurality of rows each including a plurality of color patches, one candidate row that is a candidate for a color-measured row in which a user performed color measurement, based on colorimetric values of the candidate row and reference values of respective color patches in the color chart; and performs specification processing of specifying, in a case where it is not possible to specify only one candidate row in the first specification processing, the color-measured row with use of information other than colorimetric values.
