Abstract:
A fundus camera includes an illumination optical system, an observation photographic optical system, a photographic diaphragm unit located in a position conjugate with the subject's eye in the observation photographic optical system, and an imaging unit disposed in the observation photographic optical system. The photographic diaphragm unit includes a first photographic diaphragm fixed during capturing of a still image and a second photographic diaphragm movable during capturing of a moving image. The fundus camera further includes a diaphragm driving unit configured to move the second photographic diaphragm on a plane orthogonal to an optical axis, an image recording unit configured to capture, with the first photographic diaphragm, a still image based on an output of the imaging unit and, with the second photographic diaphragm, a moving image based on an output of the imaging unit, and a display unit configured to display an image captured by the imaging unit.
