摘要： PROBLEM TO BE SOLVED: To reduce the amount of use of single-color material based on a color signal, which is obtained by converting a color signal comprised of a plurality of color components into single color, while reducing influences on processing performance. SOLUTION: In a K generation unit 50 of an image processing apparatus, toner-saving conversion expression storage section 52 stores a toner-saving conversion expression obtained by modifying a coefficient of NTSC conversion expression to reduce the amount of toner to be used.

摘要： PROBLEM TO BE SOLVED: To achieve desirable color reproduction, even when an image signal the input color gamut of which is different is given.
SOLUTION: A brightness difference acquiring unit 11 acquires brightness difference between the maximum saturation point of a first standard input color gamut and the maximum saturation point of a second input color gamut with a color reproduction zone which is outside the first input color gamut. A reference point setting unit 12 sets, as a reference point 1, a point of brightness of the maximum saturation point of the first input color gamut on a brightness axis, when an image signal to be converted is a color point of the first input color gamut. In addition, a reference point 2 is set on the side, on which the brightness is higher than that of the reference point 1, when the image signal to be converted lies outside the first input color gamut, and when it is higher than the brightness of the reference point 1. A reference point 3 is set on the side, on which brightness is lower than that of the reference point 1, when the image signal to be converted is outside the first input color gamut and when being equal to or less than the brightness of the reference point 1. Then, the image signal to be converted is converted, into a converted image signal of an output color gamut by a conversion unit 13 toward the set reference point.
