1. An image correction apparatus comprising: a representative color information calculating device which calculates color information representative of a specific image contained in an image represented by applied image data; a target color information setting device which sets target color information; a target color information modifying device which modifies the target color information, while maintaining a tint that is based upon the target color information that has been set by said target color information setting circuit, in such a manner that target brightness information calculated based upon the target color information that has been set will be the same as representative brightness information of the specific image calculated based upon the representative color information of the specific image that has been calculated by said representative color information calculating circuit; and an image data correcting circuit which corrects at least data representing the specific image in the applied image data in such a manner that the representative color information of the specific image that has been calculated by said representative color information calculating circuit will have the modified target color information obtained as a result of the modification by said target color information modifying circuit.
