A image processing apparatus includes a color converting unit (6); a registration list (35) that registers a plurality of paper profiles associated with a plurality of registered papers; a parameter managing unit (13) that includes a function of extracting a registered paper capable of approximating color reproduction characteristics of a user's paper sheet from among the registered papers registered in the registration list (35), based on a feature amount calculated from spectral reflectance characteristics of the user's paper sheet set in an image forming apparatus (42); and a user interface for receiving a user operation that instructs the parameter managing unit (13) to extract a registered paper capable of approximating the color reproduction characteristics of the user's paper sheet, and for presenting the registered paper extracted by the parameter managing unit (13) to the user.
