The present invention relates to an image processing apparatus, an image processing method, an image processing program, and an image printing apparatus, capable of solving an existing problem of color disappearance of a bright part in an image in backlighting correction. The image processing apparatus includes a specific image detection unit detecting an area including at least a part of a specific image in an input image, a difference acquisition unit acquiring a difference between brightness of the area detected by the specific image detection unit and brightness of a background area in the input image, a correction curve acquisition unit acquiring a correction curve for gradation correction on the basis of the difference, and a correction unit correcting the gradation value of a pixel, which belongs to a color gamut with a dark portion defined, from among pixels constituting the input image by using the correction curve.
