Information Processing Device, Information Processing System, And Information Processing Method

An information processing device comprising:

• an image acquisition unit configured to acquire a plurality of spectroscopic images for a plurality of spectral wavelengths as a captured image of an imaging target;
• a spectrum calculation unit configured to calculate an optical spectrum in each of pixels, based on the plurality of spectroscopic images;
• a feature wavelength detection unit configured to detect a feature wavelength corresponding to a predetermined feature condition of the optical spectrum in each of the pixels;
• a color set unit configured to calculate a feature angle corresponding to the feature wavelength in each of the pixels when a spectral wavelength range including the plurality of spectral wavelengths is allocated to a predetermined angle range of a hue circle, and set, as a feature color of a corresponding pixel, a color in the hue circle corresponding to the feature angle;
• and
• an image generation unit configured to generate a feature detection image obtained by converting each of the pixels of the captured image into the feature color corresponding to the pixel.
