ABSTRACT:
This invention has as its object to provide an image recording apparatus, which can omit a color processing calculation process for designated colors of an image when color processing results for all the colors, which may be designated upon image drawings, can be held, and can increase an image recording processing speed without impairing color reproducibility of an image. Upon conversion from color coordinate values in a color space for designating image colors of input image data from a host computer (2) into color coordinate values in a color space inherent to the recording apparatus, a CPU (1) registers, in a color processing table (7b), the color coordinate values in the color space inherent to the recording apparatus for all the colors input as image data, and performs color coordinate conversion by retrieving the color coordinate values held in the color processing table (7c) as much as possible upon execution of the color coordinate conversion in place of performing a color processing calculation in each conversion.
