Abstract
A technology is provided whereby correction may be carried out appropriately for both a person's face and other portions of an image, when performing color correction for image data of a photographic image in which a person appears. A process such as the following is carried out during color correction of image data of a photographic image. First, the image data of the photographic image is analyzed, and a first region which is part of the photographic image and in which a person's face is present is determined. Then, on the basis of the portion corresponding to the first region of the image data, a first parameter relating to color is calculated. On the basis of part of the image data corresponding to a second region which is part of the photographic image but different from the first region, a second parameter relating to color is calculated. The color tone of the data is then corrected on the basis of the first and second parameters.
