  • Patent number: 10872397
    Abstract: An device extracts a luminance that satisfies a rule from among luminance of being observed values of electromagnetic waves in a plurality of wavelength bands different mutually and calculates a first interim optical path radiance based on the luminance. The observed values is associated with each pixel constituting an observation image for each of the wavelength bands. The device calculates a final optical path radiance for each of the wavelength bands by weighting the first and a second interim optical path radiance including information on atmosphere with a weighting coefficient and adding those weighted luminance. The weighting coefficient represents reliability for an assumption of a dark pixel that is a pixel assumed not to be affected by electromagnetic waves reflected by an object. The device subtracts the final optical path radiance from all pixels of the observation image for each of the wavelength bands.
