1. A radiographic image capturing system comprising: a radiographic image capturing device that is capable of performing fluoroscopic imaging, and that carries out capture of radiographic images continuously; a radiation irradiating device that performs continuous irradiation or pulse irradiation with respect to the radiographic image capturing device at a time of fluoroscopic imaging; and a control device having a controller that affects control such that, in a case in which a frame rate of fluoroscopic imaging is low, the radiation irradiating device performs fluoroscopic imaging by continuous irradiation with respect to the radiographic image capturing device.
