Document Type and Number:
Japanese Patent JP6876283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concentration measurement system which photographs a measurement object, so as to be able to measure its concentration from chemical information correlating with color information (red (R), green (G), blue (B)) on the measurement object.SOLUTION: In a system, color information on a measurement object is set as numerical information on RGB, and is collated with a calibration curve created on the basis of the numerical information on RGB of a concentration-known sample, so that the concentration of the measurement object is measured as chemical information correlating with the color information on the measurement object.SELECTED DRAWING: Figure 2
