an illumination light source operable to illuminate an eye to be examined of a subject;

a light-intensity adjusting section operable to adjust a light intensity of the illumination light source;

a strobe emitting stroboscopic light;

an imaging device converting received light into an electrical signal;

an amplifying section amplifying the electrical signal from the imaging device according to an amplification factor;

a photography optical system guiding an image of the eye to the imaging device; and

a driving section controlling the illumination light source, the strobe, and the imaging device,

wherein the driving section photographs a still image by using only the illumination light source at a first time interval and photographs a still image by using the strobe at a second time interval after the first time interval passes, and

wherein the driving section sets an upper limit of the light intensity emitted by the illumination light source at the second time interval to exceed an upper limit of the light intensity emitted by the illumination light source at the first time interval.
