    • An object is to carry out color correction in a highly accurate manner on images acquired by various digital cameras and scanners. A color correction apparatus includes a determining unit configured to determine whether or not preprocessing for removing the effect of previously-performed color correction is required for a reference image that is used for a reference of color correction and a color correction target image on which color correction is to be carried out; a preprocessing unit configured to carry out preprocessing on a reference image and a color correction target image that is determined by the determining unit as requiring preprocessing and output a preprocessed image; a color-correction processing unit configured to acquire 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 to acquire 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 to correct the color correction target image on the basis of the acquired reference image.
    • 目的是以高精度的方式对由各种数码相机和扫描仪获取的图像进行颜色校正。 颜色校正装置包括:确定单元,被配置为确定用于去除用于颜色校正的参考的参考图像的预先执行的颜色校正的效果的预处理是否需要用于其上的颜色校正的颜色校正目标图像 要进行; 预处理单元,被配置为对参考图像执行预处理,并且所述颜色校正目标图像由所述确定单元确定为需要预处理并输出预处理图像; 颜色校正处理单元,被配置为如果所述确定单元确定所述参考图像或颜色校正目标图像不需要预处理或获取预处理的参考图像或颜色校正目标,则获取未被预处理的参考图像或颜色校正目标图像 如果确定单元确定参考图像或颜色校正目标图像需要预处理,并且基于所获取的参考图像来校正颜色校正目标图像。
