Abstract:
1. An estimation device configured to estimate a feature value of a specific component contained in a sample, comprising: a spectral estimation parameter storage module configured to store a spectral estimation parameter used to convert a plurality of band images in different wavelength bands into an optical spectrum; a calibration parameter storage module configured to store a calibration parameter used to convert the optical spectrum into the feature value; a multiband image acquirer configured to obtain a multiband image of the sample taken in a plurality of wavelength bands including at least a specified wavelength band for the specific component; an optical spectrum operator configured to compute the optical spectrum from the multiband image using the spectral estimation parameter stored in the spectral estimation parameter storage module; and a calibration processor configured to compute the feature value from the optical spectrum computed by the optical spectrum operator using the calibration parameter stored in the calibration parameter storage module.
