Abstract
An LUTpreparation sectionand an LUTpreparation sectionprepare an LUTand an LUTfor producing linear output from first raw data or second raw data. Using the LUTand LUT, an LUTconversion sectionand an LUTinverse conversion sectionconvert CMYK of the first raw data and C'M′Y′K′ of the second raw data into four color values adjusted, and an L matching LUT preparation sectionprepares an L matching LUT so that the K value of the four color values adjusted becomes equal. A K preservation 4DLUT preparation sectionprepares a K preservation 4DLUT from the four color values adjusted, the L matching LUT, and the Lab value of the first and second raw data. A 4DLUT reset sectionresets some of data in the prepared K preservation 4DLUT, whereby partial calorimetric match is intended.
