Abstract
In an example of the disclosure, a device (38) includes: an acquiring unit to obtain first reflectance output values acquired from reference samples (52) by a reference color measuring device and to obtain second reflectance output values acquired from the reference samples (52) by a second color measuring device (2); a processing unit to determine, for a plurality of wavelength values, correspondences between a first reflectance output value acquired by the reference color measuring device and a second reflectance output value acquired by the second color measuring device, and to perform, for each wavelength value, an interpolation based on the correspondences to obtain interpolation data; and a correcting unit to correct, based on the interpolation data, third reflectance output values acquired by the second color measuring device (2) from a sample of interest (12).
