An image processing apparatus converts a color image signal into a luminance signal and a color signal in a predetermined color space (111), and performs tone conversion processing on the luminance signal on the basis of a predetermined tone conversion characteristic (112). A function for chroma correction processing is then set using the luminance signal, the tone conversion-processed luminance signal, a maximum value of the luminance signal in the color space, and a luminance value when a maximum chroma is indicated in a hue region to which the color image signal belongs, as parameters (113), whereupon chroma correction processing is performed on the color signal using the luminance signal, the tone conversion-processed luminance signal, and the set function (114).
