Spectral information generation device, spectral information generation system, and spectral information generation method

A spectral information generation system comprising:

• a first spectroscopic camera configured to output first spectral information that is an imaging signal for each of a plurality of wavelength bands;
• a second spectroscopic camera configured to output second spectral information that is an imaging signal for each of a plurality of wavelength bands different from the plurality of wavelength bands of the first spectroscopic camera but partially including wavelength bands common to the plurality of wavelength bands of the first spectroscopic camera;
• a distance information calculation unit configured to calculate distance information from the first spectral information and the second spectral information;
• and
• a spectroscopic processing unit configured to generate output spectral information from the first spectral information and the second spectral information.
