1. A slit lamp microscope comprising:
an illumination system including an illumination light source and configured to project slit light onto an anterior segment of a subject's eye from a first direction;
a first photographing system including a lens and configured to photograph the anterior segment onto which the slit light is being projected, from a second direction different from the first direction;
a second photographing system configured to photograph the anterior segment;
a fixation system including a fixation light source and configured to output fixation light for fixation of the subject's eye;
a movement mechanism including an actuator and configured to be capable of moving the illumination system and the first photographing system; and
a controller circuit configured to perform a first control for the movement mechanism to move at least the illumination system, a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light, and a third control for the second photographing system to photograph the anterior segment a plurality of times in parallel with the first control and the second control.
