The second acquisition unit acquires an optical image obtained by imaging the subject facing radiography with a camera. The specifying unit specifies a region of the measurement target part in the optical image based on the designation information. The extraction unit extracts a region in a radiation image corresponding to the region of the measurement target part as a measurement region of the bone density based on correspondence relationship information between pixels of the radiation image and pixels of the optical image.
