    摘要: A color identifying apparatus for identifying the color of a reaction surface which has caused a color reaction with a gas to be specified includes a storage that, for every set of a plurality of referential color coordinates generated pixel by pixel from RGB bitmap images of a reaction surface which has caused a color reaction with a gas, stores pieces of reference data, which respectively represent both each coordinate on a chromaticity diagram and frequencies that depend on the numbers of the referential color coordinates corresponding to each one of the coordinates on the chromaticity diagram, and identification information for identifying the reaction surface; an image capturing unit that captures an image of the reaction surface and generates RGB bitmap images of the reaction surface; an arithmetic unit that generates a plurality of measured color coordinates pixel by pixel from the RGB bitmap images generated by the image capturing unit, generates measured data, which represents both each coordinate on the chromaticity diagram and frequencies that depend on the numbers of the measured color coordinates corresponding to each one of the coordinates on the chromaticity diagram, specifies one piece of the reference data which corresponds to the measured data by checking the measured data against each piece of the reference data, and specifies the identification information which is related to the identified piece of the reference data; and an output unit that outputs the identification information specified by the arithmetic unit.
