Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, photography system, and movement mechanism. The illumination system projects slit light onto an anterior segment of an eye. The photography system includes an optical system and image sensor. The optical system directs light coming from the anterior segment onto which the slit light is being projected. The image sensor includes a light detecting plane that receives the light directed by the optical system. The movement mechanism moves the illumination and photography systems. The subject plane along the optical axis of the illumination system, the optical system, and the light detecting plane satisfy the Scheimpflug condition. The photography system acquires a plurality of images of the anterior segment by performing repetitive photography in parallel with movement of the illumination and photography systems performed by the movement mechanism.
