1. A radiography system comprising:
a radiation source that irradiates a subject with radiation;
a camera that is provided in the radiation source and images visible light reflected from the subject irradiated with light having uniform brightness to output an optical image; and
a processor,
wherein the processor is configured to:
acquire the optical image,
derive spinal column shape information representing a shape of a spinal column of the subject based on the optical image,
extract a feature point of the subject from the optical image,
extract derivation reference information for deriving the spinal column shape information from the feature point,
derive a polynomial representing the shape of the spinal column as the spinal column shape information based on the derivation reference information,
display, on a display, a spinal column shape derivation button that is selected to derive the spinal column shape information, and
prior to the derivation of the spinal column shape information based on the optical image:
acquire information regarding a body height of the subject,
extract right and left shoulder joint points and right and left hip joint points of the subject, as the feature point,
determine whether or not the derivation of the spinal column shape information based on the optical image is needed, based on the body height of the subject and a length of a line that connects a middle point of a line connecting the right and left shoulder joint points and a middle point of a line connecting the right and left hip joint points, and
disable the displayed spinal column shape derivation button upon determining that the derivation of the spinal column shape information is not needed.
