To suppress effectively an image horizontal stripe in a radiation image caused by disturbance.SOLUTION: A control device of a radiation image pickup device, comprises: a disturbance source specification part 12a specifying a kind of a disturbance source to be handled； a frequency measurement part 12b measuring a frequency of disturbance generated by the disturbance source； a first adjustment part 13a controlling the disturbance source so as to correspond a period of the disturbance generated by the disturbance source to a prescribed period in accordance with a timing for reading out an electric charge from each photoelectric conversion element of a sensor array； and a second adjustment part 13b controlling a start timing of a reading flow of the electric charge in a mine image acquisition mode or a dark image acquisition mode so as to correspond the reading interval in the same pixel region of a main image and a dark image to the period of the disturbance generated by the disturbance source. The first adjustment part 13a and the second adjustment part 13b are selectively executed on the basis of the kind of the disturbance source.SELECTED DRAWING: Figure 1【課題】外乱に起因した放射線画像内の画像横縞をより効果的に抑制すること。【解決手段】放射線画像撮像装置の制御装置であって、対処すべき外乱源の種別を特定する外乱源特定部１２ａと、前記外乱源が発する外乱の周波数を測定する周波数測定部１２ｂと、前記外乱源が発する外乱の周期を前記センサアレーの各光電変換素子から電荷を読出すタイミングに係る所定の周期に対応させるように、前記外乱源を制御する第１の調整部１３ａと、本画像と暗画像の同一画素領域における読み出し間隔を前記外乱源が発する外乱の周期に対応させるように、本画像取得モード又は暗画像取得モードにおける電荷の読出しフローの開始タイミングを制御する第２の調整部１３ｂと、を備え、前記第１の調整部１３ａと前記第２の調整部１３ｂとは、前記外乱源の種別に基づいて選択的に実行される。【選択図】図１
