Abstract:
In order to perform observation and imaging by the same image capture unit, an ophthalmologic imaging method includes illuminating a fundus of an eye to be inspected with light having a first wavelength, guiding return light from the fundus to an image capture unit through a focus lens so as to obtain an in-focus position of the focus lens in accordance with the light having the first wavelength, illuminating the fundus with light having a second wavelength different from the first wavelength, and guiding return light from the fundus to the image capture unit through the focus lens so as to obtain an image of the fundus. The focus lens is moved to an in-focus position for the light having the second wavelength based on a wavelength difference between the light having the first wavelength and the light having the second wavelength.
