PROBLEM TO BE SOLVED: To increase lightness difference of an illumination component at a required part of an image, in dodging processing. SOLUTION: An imaging means images an object light; an illumination component extracting means extracts an illumination component from a photographed image by the imaging means; a reflectance component extract means extracts reflectance component from the photographed image; a compression characteristic setting means sets at least two prescribed regions, with respect to the photographed image, sets a compression characteristics for emphasizing the lightness difference between the regions; a compression means compresses the dynamic range of the illumination component, on the basis of the compression characteristics set by the compression characteristics setting means; and an image generating means generates a new image, on the basis of the compressed illumination component whose dynamic range has been compressed and of the reflectance component.
