1. A method of acquiring a facial image of a subject to analyze a degree of ocular proptosis, the method comprising:
acquiring a front image of the subject's face while guidance is given to satisfy a first photographing condition, wherein the first photographing condition includes a condition in which the subject's both eyes are placed at predetermined areas in a first captured image;
generating panorama guidance on the basis of position information of a first point and a second point extracted from the front image, wherein the panorama guidance is generated in a horizontal direction with respect to a front of the face, and the first point and the second point are spaced apart from each other in a vertical direction with respect to the front of the face;
providing guidance on movement of a photographing device to acquire a preview image corresponding to the panorama guidance, which comprises monitoring whether a vertical separation distance between the first point and the second point extracted from the preview image is within a predetermined error range with respect to an initial separation distance; and
acquiring a side image of the subject's face while guidance is given to satisfy a second photographing condition, wherein the second photographing condition includes a condition in which a vertical separation distance between the first point and the second point extracted from a second captured image is within the predetermined error range with respect to an initial separation distance,
wherein in order for the acquired images to be used in calculating the degree of ocular proptosis, the first captured image includes iris areas of the subject and the second captured image includes an outer canthus and a cornea of one of the subject's eyes.
