Title:
CHARACTERISTIC VALUE MEASUREMENT DEVICE, METHOD, AND PROGRAM USING COLOR IMAGE
Document Type and Number:
WIPO Patent Application WO/2019/054016
Kind Code:
A1
Abstract:
This characteristic value measurement device is for measuring characteristic values of a detected substance in a sample, wherein the device comprises: an imaging means that captures a color image on a test paper onto which the sample has been dripped; and a computation means that executes prescribed computation on the basis of the captured color image and calculates the characteristic values of the detected substance in the sample on the basis of the results of the computation. The test paper retains a color-reaction reagent with wavelength characteristics such that the reflectance at a first wavelength represents a maximum value and the reflectance at a second wavelength that differs from the first wavelength represents a minimum value.
