Abstract: An image processing apparatus includes a profile generating section, a designating section, a calculating section and a correcting section. The profile generating section generates a color conversion profile based on first calorimetric values obtained from a first color chart output from a target device and second calorimetric values obtained from a second color chart from an output device other than the target device. The calculating section calculates difference information between a first data value obtained by converting a designated color into a device-independent color space and a second data value obtained by converting the designated color using the color conversion profile into an intermediate color and converting the intermediate color using the device-independent color space. The correcting section corrects the first calorimetric values based on the difference information. The profile generating section generates the color conversion profile again based on the corrected first colorimetric values.
