Abstract
Provided is an image processing device including: an image read-in unit 51 which reads in one or more observation images which retain observation results from one or a plurality of wavelength regions; a reflection-absorption band region deletion unit 52 which deletes, from each of one or more of the observation images, observation results with respect to a reflection-absorption band region, and generates reflection-absorption band-deleted images; a coefficient constituent proportional value computation unit 53 which, using the reflection-absorption band-deleted images, derives a proportional value of a coefficient constituent for each wavelength band used in the observation; and a coefficient constituent deletion unit 54 which, on the basis of the obtained proportional values of the coefficient constituents for each of the wavelength bands, deletes the coefficient constituents from each of the observation values included in the one or more observation images, and generates illumination-corrected images.
