Abstract:
1. An image processing apparatus that separates image data in an N-dimensional first signal format, where 3<N, into image data in a second signal format, the second signal format indicating the amount of a colorant of each color used in an image output apparatus, the apparatus comprising: an input unit configured to acquire input image data in the first signal format; a conversion unit configured to convert the input image data in the first signal format into image data in an M-dimensional third signal format, where 3<M≦N; and a color separation unit configured to separate the converted image data in the third signal format into image data in the second signal format, using an M-dimensional color separation LUT whose input values are in the third signal format and whose output values are in the second signal format, wherein with respect to a pixel distribution, a correlation between each component of the converted image data in the third signal format is lower than a correlation between each component of the input image data in the first signal format.
