A radiographic image capturing system includes a radiographic image capture device, a radiation irradiation device, and a control device. The radiographic image capture device is capable of wired and wireless communications, and is capable of fluoroscopic imaging in which radiographic images are successively captured at notified synchronization timings or at a predetermined frame rate. The radiation irradiation device irradiates radiation toward the radiographic image capture device during fluoroscopic imaging, with continuous irradiation or pulse irradiation. The control device includes a wireless communication unit, a wired communication unit, and a controller that, if communication with the radiographic image capture device is performed by the wireless communication unit, prohibits fluoroscopic imaging with pulse irradiation in which the synchronization timings are notified to the radiographic image capture device and radiation is irradiated from the radiation irradiation device in pulses matching the notified synchronization timings.
