Abstract:
In an image processing apparatus of the present invention, interpolation operations are performed with a LUT to obtain CMY image data corresponding to input RGB image data. The image processing apparatus includes a gamut selecting section for selecting a gamut corresponding to an inputted image, from an RGB color space, based on input RGB image data; a LUT writing section for changing CMY image data in the LUT to CMY image data corresponding to grid points contained in the selected gamut; and a position information changing section for writing position information in a memory, wherein the position information indicates RGB color space positions of the grid points contained in the selected gamut. Thus, the image processing apparatus of the present invention can save memory space.
