Abstract: Provided is an ophthalmologic apparatus, including: a scan unit configured to repeat two-dimensional scanning on a fundus of an eye to be inspected with measuring light; an image generation unit configured to generate a two-dimensional image of the fundus based on reflected light of the measuring light from the fundus that is two-dimensionally scanned; and a control unit configured to control, in the two-dimensional scanning, an amount of the measuring light that is radiated to the fundus and is not used to generate the two-dimensional image to be smaller than an amount of the measuring light that is radiated to the fundus and is used to generate the two-dimensional image.

Abstract: Provided is an ophthalmologic imaging apparatus capable of imaging with reduced imaging time based on a combination of an imaging type and a mydriatic state of an eye to be inspected. The ophthalmologic apparatus includes an acquiring unit configured to acquire information about a mydriatic state of a pupil of a person to be inspected, and a determining unit configured to determine an imaging order for imaging one of left and right eyes of the person to be inspected a plurality of times and imaging the other eye in accordance with the information about the mydriatic state acquired by the acquiring unit.

Abstract: Provided is an ophthalmologic examination method including a first control step of driving a focus unit based on an index image acquired by projecting an index to an eye to be inspected in a state of setting light intensity for illuminating the eye to be inspected to a first light intensity, a second control step of driving the focus unit based on the index image acquired in a state of setting the light intensity to a second light intensity higher than the first light intensity, and a memory step of storing specific information on the eye to be inspected during the first control step and the second control step. The second control step is executed after driving the focus unit to a position stored in the memory step in the case of storing again the specific information after storing the specific information.

Abstract: Provided is an ophthalmologic apparatus having an automatic focusing function and capable of imaging a subject in focus, including: a light intensity control unit for controlling a light intensity of light guided to an object to be inspected; an imaging unit for imaging the object to be inspected which is illuminated by the light; a focus state detection unit for detecting a focus state of the imaging unit with respect to the object to be inspected based on an output from the imaging unit; a focus lens drive unit for driving a focus lens based on the focus state detected by the focus state detection unit; and a drive control unit for controlling the focus lens drive unit to operate in accordance with timing when the light intensity of the light is changed by the light intensity control unit.

Abstract: An ophthalmologic apparatus includes a focusing unit configured to focus, on an imaging unit, a return beam from a fundus of a subject's eye, a first drive unit configured to drive the focusing unit based on an index image obtained by imaging, using the imaging unit, a return beam from the fundus resulting from an index projected on the fundus by a projection unit, and a second drive unit configured to drive, after the first drive unit has driven the focusing unit, the focusing unit based on a contrast of a fundus image obtained by imaging, using the imaging unit, a return beam from the fundus, the fundus having been illuminated by an illumination unit.
