For sharing, as a second profile for a second output device, a known first profile for converting input device-dependent image data into first output device-dependent image data by performing a pre-gradation converting process, a color converting process, and a post-gradation converting process on the input device-dependent image data, a differential between a one-dimensional gradation conversion curve of a first color image output device and an inverse conversion curve of a one-dimensional gradation conversion curve of a second color image output device is determined by a differential generator, and then the first profile and a differential table are used as the second profile for the second color image output device.
