Document Type and Number:
Japanese Patent JP7200516
Kind Code:
B2
Abstract:
To provide an ocular fundus imaging apparatus for capturing an ocular fundus image in which artifact is suppressed.SOLUTION: An ocular fundus imaging apparatus includes an imaging optical system including a radiation optical system for radiating an illumination light onto the ocular fundus through an objective lens and a light reception optical system that shares the objective lens with the radiation optical system and includes a light receiving element for receiving an ocular fundus reflection light of the illumination light, and acquires an ocular fundus image on the basis of a signal from the light receiving element. A control unit acquires refractivity information which is the information on the refractivity of an eye to be examined, and executes artifact suppression processing for suppressing generation of an artifact based on the reflection of the illumination light by the objective lens according to the refractivity. In more detail, an imaging mode is switched between a first mode in which the artifact suppression processing is not executed when capturing the ocular fundus image, and a second mode in which the artifact suppression processing is executed when capturing the ocular fundus image on the basis of the refractivity.SELECTED DRAWING: Figure 12
