摘要： A radiographic image capture system includes a radiation detector, a radiation source, a generator, and a controller. The radiation detector includes plural pixels that generate electrical charges upon irradiation with radiation and that accumulate the electrical charges. The radiation source irradiates radiation onto the radiation detector. The generator reads the respective electrical charges accumulated in each of the pixels as electrical signals and generates image data. The controller causes the generator to read the electrical charges accumulated in each of the pixels at a specific frame rate in cases where continuous fluoroscopic imaging is performed, and, in a case in which a specific condition is satisfied, causes the radiation source to reduce the radiation amount being irradiated and causes the generator to perform thinned reading to read out the pixels one section at a time while extending the reading cycle of the electrical charges for each pixel.
