PROBLEM TO BE SOLVED: To provide an image processor and an image processing method by which gray reproduction is performed by the single color of K in the image processing of the color conversion of converting the image data of RGB to the image data of the color space of a prescribed color system, converting them to the image data of YMC on the basis of the converted image data of the color space of the prescribed color system and converting them to the image data of YMCK on the basis of the image data of YMC. SOLUTION: A printer driver 14 is provided with a multidimensional lookup table(DLUT) 16 for performing conversion to the image data of YMC after performing correction to follow YMC axes matched with a colorimetric value in Y=M=C at the time of converting the image data of RGB to the color spatial data of L*a*b*, adjusting a lightness range and converting them to the image data of YMC. An UCR processing part 22 for generating the color K and performing the conversion to the image data of YMCK on the basis of the image data of YMC outputted from the printer driver 14 is provided. |
