A feature amount converting unit (12) performs a color conversion of an input data. A history storage unit (11) stores history information about a measurement of a color chart including conversion values of measured values of the color chart. An arithmetic unit (10) compares the history information with new input information for measurement of the color chart, and determines the number of color patches based on a result of the comparison. A profile updating unit (15) updates a printer profile based on a determined color chart data. <IMAGE> |
