ABSTRACT:
An LUT1preparation section1and an LUT2preparation section2prepare an LUT1and an LUT2for producing linear output from first raw data or second raw data. Using the LUT1and LUT2, an LUT1conversion section3and an LUT2inverse conversion section4convert 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 section5prepares an L matching LUT so that the K value of the four color values adjusted becomes equal. A K preservation 4DLUT preparation section6prepares 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 section7resets some of data in the prepared K preservation 4DLUT, whereby partial calorimetric match is intended.
