To increase the accuracy of selection of a significant radiographic image from a plurality of radiographic apparatuses capable of capturing radiographic images.SOLUTION: A radiographic apparatus includes a plurality of radiographic apparatuses, each radiographic apparatus including a radiation detection unit which performs image capturing operation to capture a radiographic image, the plurality of radiographic apparatuses being a first radiographic apparatus and a second radiographic apparatus which includes a radiation detection unit with a different sensitivity from the radiation detection unit of the first radiographic apparatus. The radiographic system includes: a setting part which changes the sensitivity of at least one of both the first radiographic apparatus and the second radiographic apparatus to reduce the sensitivity difference between the sensitivity of the first radiographic apparatus and the sensitivity of the second radiographic apparatus； and an image acquisition part which acquires a radiographic image from a radiographic apparatus selected from the first and second radiographic apparatuses, on the basis of a signal output from the first and second radiographic apparatuses on which the change setting was performed.SELECTED DRAWING: Figure 8【課題】 撮像可能な複数の放射線撮像装置からの有意な放射線画像の選択の精度を向上させる。【解決手段】 放射線に基づく放射線画像を撮像するための撮像動作を行う放射線検出部を各々が含む複数の放射線撮像装置であって、第一の放射線撮像装置と、第一の放射線撮像装置の放射線検出部と感度が異なる放射線検出部を含む第二の放射線撮像装置と、を含む放射線撮像システムは、第一の放射線撮像装置の感度と第二の放射線撮像装置の感度の感度差を小さくするように、第一の放射線撮像装置及び第二の放射線撮像装置の少なくとも一方の感度を変更する設定を行う設定部と、変更する設定が行われた第一の放射線撮像装置及び第二の放射線撮像装置から出力された信号に基づいて、第一の放射線撮像装置及び第二の放射線撮像装置から選択された放射線撮像装置から放射線画像を取得する画像取得部と、を含む。【選択図】 図８
