1. An information processing apparatus comprising:
a control unit configured to
acquire characteristic data related to a spectroscopic sensitivity characteristic of an imaging apparatus,
acquire photographing-side spectroscopic data related to a spectroscopic distribution characteristic of a light source in a photographing environment in which the imaging apparatus performs imaging,
acquire color spectroscopic data related to a spectroscopic reflectance characteristic of a predetermined color,
calculate an RGB value output by the imaging apparatus when imaging of the predetermined color is performed by using the imaging apparatus by using the characteristic data, the photographing-side spectroscopic data, and the color spectroscopic data,
acquire display-side spectroscopic data related to a spectroscopic distribution characteristic of a light source in a display environment in which imaged data imaged by the imaging apparatus is displayed on a display apparatus,
calculate an XYZ value when the predetermined color is displayed on the display apparatus by using the display-side spectroscopic data and the color spectroscopic data, and
calculate conversion information for converting the RGB value into the XYZ value.
