Claim:
1. An ophthalmologic imaging method comprising: illuminating a fundus of an eye to be inspected with light having a first wavelength; obtaining a first in-focus position for light having the first wavelength based on return light of the light having the first wavelength from the fundus, the return light of the light having the first wavelength being guided to an image capture unit through a focus lens; moving, before instructing by an imaging switch used for acquiring an image of the fundus by illuminating the fundus with light having a second wavelength different from the first wavelength, the focus lens to a second in-focus position for light having the second wavelength based on (a) the first in-focus position and (b) a wavelength difference between the light having the first wavelength and the light having the second wavelength; illuminating the fundus of the eye to be inspected with the light having the second wavelength after the instructing by the imaging switch; and acquiring an image of the fundus based on return light of the light having the second wavelength from the fundus, the return light of the light having the second wavelength being guided to an image capture unit through the focus lens that had been moved to the second in-focus position.
