Color correction apparatus

A method of color correction comprising:

• a determining step of determining whether or not preprocessing for removing the effect of previously-performed color adjustment is required for a reference image that is used as a reference of color adjustment and a color correction target image on which color correction is to be carried out;
• a preprocessing step of carrying out preprocessing on the reference image and color correction target image that are determined as requiring preprocessing and outputting preprocessed images;
• and
• a color correction step of acquiring a reference image or color correction target image that is not preprocessed if the determining unit determines that the reference image or color correction target image does not require preprocessing or acquiring a preprocessed reference image or color correction target image if the determining unit determines that the reference image or color correction target image requires preprocessing, and correcting the color correction target image on the basis of the acquired reference image.

A color correction program to be executed by a computer, the program comprising:

• a determining step of determining whether or not preprocessing for removing the effect of previously-performed color adjustment is required for a reference image that is used as a reference of color adjustment and a color correction target image on which color correction is to be carried out;
• a preprocessing step of carrying out preprocessing on the reference image and color correction target image that are determined as requiring preprocessing and outputting preprocessed images;
• and
• a color correction step of acquiring a reference image or color correction target image that is not preprocessed if the determining unit determines that the reference image or color correction target image does not require preprocessing or acquiring a preprocessed reference image or color correction target image if the determining unit determines that the reference image or color correction target image requires preprocessing, and correcting the color correction target image on the basis of the acquired reference image.
