An image processing apparatus transforms a color signal of a first color space defined by a predetermined standard into a color signal of a second color space which is defined according to display characteristics of a display device and has a color gamut wider than a color gamut of the first color space, and outputs the transformed color signal. More specifically, the image processing apparatus includes: a first correction unit configured to, for each of color values making up the color signal of the first color space, correct a color value exceeding a first upper limit to the first upper limit and correct a color value falling below a first lower limit to the first lower limit, the first upper limit and the first lower limit being necessary for expressing the color gamut of the second color space; a color space transformation unit configured to transform the color signal of the first color space corrected by said first correction unit, into the color signal of the second color space; and a second correction unit configured to, for each of color values making up the color signal of the second color space generated by said color space transformation unit, (i) correct a color value exceeding a second upper limit to the second upper limit and correct a color value falling below a second lower limit to the second lower limit, and (ii) output the corrected values, the second upper limit and the second lower limit being values which can be displayed by the display device.
