In tomosynthesis imaging which uses a radiation source that generates radiation and an Al filter and a Cu filter that change the quality of the radiation, irradiates a breast with the radiation emitted from the radiation source at a plurality of irradiation positions having different irradiation angles, and switches the Al filter and the Cu filter at each of the irradiation positions such that the radiation having different qualities is emitted to capture a plurality of radiographic images of the breast at each of the irradiation positions, a CPU performs control to set a last filter used at an n-th irradiation position as an initial filter used at an (n+1)-th irradiation position.
