PROBLEM TO BE SOLVED: To prevent degradation in image quality and realize color reproduction of high image quality, in color transformation definition making the best use of color reproduction property. SOLUTION: A color is fixed on an L* axis of a first to a fifth ranges L11-L15 within a first intensity region L110 at a second image apparatus. Then, an intensity color line, of which the intensity changes with a constant ratio in the saturation direction, is established from a demarcation point of each range on the L* axis. Next, an intensity color line is established in parallel to a C* axis, so that intensity may become constant in the saturation direction from a demarcation point of a ninth and a tenth ranges L19 and L20 within a second intensity region L120 at the second image apparatus. Then, a color is fixed on the L* axis of a sixth to an eighth ranges L16-L18 within the first intensity region L110, and an intensity color line, of which the intensity changes with a constant ratio in the saturation direction, is established from a demarcation point of each range on the L* axis.
