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.

Abstract: A fundus camera, which does not take time for adjustment of illumination light amount and focusing even if brightness of the fundus is different for each eye to be inspected, includes an illumination unit for illuminating the fundus of the eye to be inspected, a photometry unit for performing photometry of reflection light from the fundus illuminated by the illumination unit, an illumination light amount control unit for controlling a light amount of the illumination unit, a focus detection area determining unit for determining a focus detection area with respect to a fundus image taken by an image pickup unit, and a focus detection unit for detecting a focus position in the area determined by the focus detection area determining unit. The photometry unit calculates a photometry value of the focus detection area, and the illumination light amount is controlled based on the photometry value.

Abstract: An ophthalmologic apparatus includes a focusing lens provided in an optical path connecting a subject's eye and an imaging unit, a diopter correction lens provided in the optical path to be insertable and removable, and a position determination unit configured to determine a position of the focusing lens on the optical path in a state where the diopter correction lens is inserted, based on an in-focus state where the diopter correction lens is not inserted.

Abstract: An ophthalmologic apparatus includes: a position control unit configured to control a position changing unit which changes a position of an examination unit, such that fine movement driving of the examination unit is performed in a case where a tilt angle of the operating member is smaller than a first angle, and coarse movement driving of the examination unit is performed in a case where the tilt angle of the operating member is equal to or greater than the first angle; and an angle control unit configured to control an angle changing unit which changes the angle of the operating member such that the tilt angle of the operating member is automatically changed to a second angle which is smaller than the first angle, in accordance with a change from the coarse movement to the fine movement.

Abstract: There is provided an electric joystick for an ophthalmologic apparatus which exhibits a relatively small difference from operation of a manual joystick when performing alignment of an ophthalmologic apparatus. An ophthalmologic apparatus including an inspection unit which images or measures part of an eye to be inspected, a driving unit which moves the inspection unit, and an operation knob tiltable in an arbitrary direction includes a detection unit which detects a detected amount corresponding to the operation force applied to the operation knob in a case where the tilt angle of the operation knob tilted from a non-tilt position exceeds a predetermined angle, and a control unit which drives the driving unit in accordance with the detected amount detected by the detection unit.
