7. An image processing method, comprising:
by a processor:
acquiring a fundus image;
generating a first sharpened image by performing a first sharpening processing using a first parameter on an entire region of the fundus image, and generating a second sharpened image by performing a second sharpening processing using a second parameter, which is different from the first parameter, on the entire region of the fundus image; and
generating a sharpened fundus image by generating a sharpened central image by combining the first sharpened image and the second sharpened image at a first combination ratio, and by generating a sharpened peripheral image of a peripheral region of the sharpened central image by combining the first sharpened image and the second sharpened image at a second combination ratio that is different from the first combination ratio.
