PROBLEM TO BE SOLVED: To make it possible to switch contents of transformation by a memory of small capacity. SOLUTION: A color transformation device 100 for converting input picture data into color data suitable for reproduction of the picture data is provided with a color transformation means 105 capable of changing a parameter for regulating contents of transformation, a storage means 110 for storing a reference parameter SP corresponding to a specific combination of input and output devices, storage means 111, 112 for storing difference dataΔP1,ΔP2 indicating the contents of a difference between a non-reference parameter corresponding to the other combination of input and output devices and the reference parameter SP, and a parameter setting means 901 for supplying the reference parameter SP to the means 105 in the case of the specific combination, and in the case of the other combination, generating the non-reference parameter on the basis of the difference dataΔP1,ΔP2 and supplying the non-reference parameter to the means 105.
