Abstract
In an image representing an observed ground surface area, the device calculates an optical-path-radiance with a high degree of accuracy. An image information processing device 3 includes: a storage unit 31 that associates and stores observation images representing the results of observing electromagnetic waves of a plurality of different wavelength bands reflected from a ground surface, information representing the wavelength bands, and information representing the observation environment; a first intermediate-optical-path-radiance calculation unit that, for each of the wavelength band, makes the radiance of a dark pixel meeting a radiance standard from among pixels composing an associated observation image an intermediate-optical-path-radiance; an irradiance calculation unit that calculates the irradiance from sunlight for each of the wavelength band on the basis of the information representing the observation environment; and a final-optical-path-radiance calculation unit that calculates a final-optical-path-radiance for each of the wavelength band on the basis of the irradiance and intermediate-optical-path-radiance.
