Claims (3)

  1. A light source for irradiating light toward the fundus of the eye to be examined, a focusing optical member arranged to be movable in the optical axis direction by a drive mechanism, and a light receiving element for receiving reflected light from the fundus of the eye to be examined A photographing optical system for photographing a fundus image of the eye to be examined;
    Control means for controlling driving of the drive mechanism, and acquiring a fundus image of the eye to be examined based on a light reception signal output from the light receiving element,
    The control means includes
    Moving the focusing optical member to obtain images at a plurality of positions;
    Obtaining a luminance frequency distribution of images acquired at a plurality of positions, and using the frequency distribution, obtaining a change characteristic of a luminance value having a frequency equal to or higher than a predetermined threshold with respect to the position of the optical member;
    An ophthalmologic photographing apparatus comprising: obtaining a focus position of the focus optical member based on the change characteristic; and moving the focus optical member to a position corresponding to the focus position.
  2. The ophthalmologic photographing apparatus according to claim 1.
    The imaging optical system is an imaging optical system for acquiring a fundus front image of the eye to be examined,
    The control means acquires a fundus front image based on a light reception signal output from the light receiving element, differentiates the front image, and obtains a frequency distribution of luminance in the differentiated front image. Ophthalmic imaging device.
  3. The ophthalmologic photographing apparatus according to claim 1.
    The photographing optical system includes an optical scanner that scans light emitted from the light source on the fundus of the eye to be examined, and receives light that is reflected by the measurement light from the fundus of the eye to be examined and reference light. An imaging optical system for receiving a tomographic image of the eye to be examined,
    The ophthalmologic photographing apparatus characterized in that the control means acquires a fundus tomographic image based on a light reception signal output from the light receiving element, and obtains a luminance frequency distribution in the tomographic image.
