First Claim
1. An image correction method comprising the steps of:
- specifying a region including the face of one person in an image of people as a subject of the image displayed in a screen of image display means, in response to an input from an operator;
extracting a correction target region including at least the face of the person in the image, based on information on at least one of hue, saturation, lightness, and a position of an outline of the specified region;
setting a degree of correction to be carried out on each position in the correction target region, in such a manner that the degree of correction becomes lower from the inside of the correction target region to the outside thereof near a boundary of the correction target region; and
correcting at least one of hue, saturation and lightness in the correction target region, based on the degree of correction.
