Abstract: An ophthalmologic apparatus obtains a suitable defocus state early in split AF even immediately after the apparatus shifts to an fundus observation state. At the time of focus state detection immediately after the shift to the fundus observation state, the apparatus tarns the fundus observing illumination light off if a focus determination unit determines that the defocus amount is equal to or more than a predetermined value, and turns the fundus observing illumination light on if the focus determination unit determines that an in-focus state immediately before photographing is obtained, thereby allowing the examiner to check a fundus state immediately before photographing.

Abstract: An ophthalmic apparatus includes an illumination optical system which projects an illumination light beam from an illumination light source onto the fundus of the eye to be examined and an imaging optical system which guides reflected light from the fundus to imaging part. The ophthalmic apparatus calculates the contrast value of the fundus image formed by the imaging part, and focuses the imaging optical system on the fundus by moving a focus lens in the optical-axis direction of the imaging optical system based on the contrast value obtained by the calculation. The apparatus adjusts the contrast value obtained by the above calculation based on the position of the focus lens in the optical-axis direction.

Abstract: When an observation state by an infrared LED 10 is changed to a photographing state by a xenon lamp 3, a movable mirror 16 is pulled upward and an optical path is switched to an image sensor 17 side. A light guide 22a is shifted by an alignment index drive motor 23 so that an incident portion of an alignment index is shifted from a visible LED 22b to direct to an infrared LED 22c. An outgoing portion of the light guide 22a is set at a position where an image is formed on the image sensor 17 by a wavelength of the infrared LED 22c when an operation distance is appropriate. While changing a luminescent color, a position of a luminescent point of the alignment index is changed by switching the LED by the shift of the light guide 22a.
