A radiography apparatus (1) includes a radiation emitting device (10) that irradiates a subject (H) with radiation, a camera (13) that captures an image of the subject (H) to acquire a captured image (G1) of the subject, and a radiation detector (30) that detects the radiation transmitted through the subject (H) and generates a radiographic image of the subject (H). The driving state of at least one of the radiation emitting device (10) or the radiation detector (30) is controlled on the basis of whether the radiation detector (30) is included in the captured image (G1).
