Abstract:
1. An imaging apparatus comprising: a photographing unit having an optical system for photographing an object through the optical system to generate an image of the object; a combining unit for correcting displacement of plural images of the same object generated by the photographing unit and for combining the plural images whose displacement has been corrected, thereby generating a combined image; and a limb-darkening compensating unit for compensating for limb darkening in the combined image generated by the combining unit based on limb-darkening characteristics of the optical system; wherein the limb-darkening compensating unit: (i) calculates a limb-darkening characteristic component of each of the plural images, (ii) corrects positions of the limb-darkening characteristic components of the plural images to combine said limb-darkening characteristic components, thereby generating a limb-darkening characteristic compensation value, and (iii) compensates for limb darkening in the combined image using the limb-darkening characteristic compensation value.
