PROBLEM TO BE SOLVED: To provide a mechanism which can suppress deterioration of image quality in a composite image of a subject in performing radiography on the subject by using a plurality of FPDs for automatically detecting the irradiation of radiation related to the radiography.SOLUTION: A radiographic apparatus includes: a plurality of FPDs of FPD 120-1 and FPD120-2 which detect radiation and accumulate electric charges an irradiation determination part 141 which drives one of the plurality of the FPDs 120 of FPD 120-1 and 120-2 for determining whether the radiation related to radiography is emitted or not in accordance with the charge amount of the electric charges accumulated in one of the FPDs 120 and an imaging control part 142 which drives all of the FPDs of FPD 120-1 and 120-2 and makes the FPDs accumulate the electric charges by the detection of the radiation related to the radiography when the irradiation determination part 141 determines that the radiation related to the radiography is emitted.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】放射線撮影に係る放射線が照射されたことを自動的に検出する複数のFPDを用いて被写体の放射線撮影を行う際に、被写体の合成画像における画質の低下を抑制できる仕組みを提供する。【解決手段】放射線を検出して電荷を蓄積する複数のFPD120-1及び120-2と、複数のFPD120-1及び120-2のうちの1つのFPD120を駆動させて、当該1つのFPD120に蓄積された電荷の電荷量に応じて放射線撮影に係る放射線が照射されたか否かを判定する照射判定部141と、照射判定部141において放射線撮影に係る放射線が照射されたと判定された場合に、全てのFPD120-1及び120-2を駆動させて放射線撮影に係る放射線の検出による電荷の蓄積を行わせる撮影制御部142を備える。【選択図】図1
