Information processing apparatus and information processing method

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.
