摘要
A color measuring device includes a unit configured to calculate a reference-value matrix for converting imaged reference RGB value of a reference color patch a reference colorimetric value of the reference color patch; a unit configured to convert a color-measurement RGB value of a color measurement object into an imaged colorimetric value of the color measurement object by using the corresponding reference-value matrix; a unit configured to select reference color patches of which the reference colorimetric values each have a close distance from the imaged colorimetric value in the predetermined color space; a unit configured to select, as selection RGB values, the imaged reference RGB values of the selected patches; a unit configured to calculate a selection-RGB-value matrix for converting the selection RGB values into the reference colorimetric values; and a unit configured to convert the color-measurement RGB value into a colorimetric value by using the selection-RGB-value matrix.
