Abstract

【課題】 撮影モードに拘わらず、画像補正を適切に行えるようにする。 【解決手段】 X線撮影装置に設定されている撮影モード(動画撮影モード/静止画撮影モード)それぞれに対し、異なるゲイン補正信号GSA、GSBを用いて補正処理を行うことにより、静止画撮影モードと動画撮影モードとでゲイン特性が異なる撮像手段を用いてX線撮影装置を構成した場合であっても補正エラーの低減された画像を取得することが可能となるようにする。 【選択図】 図1
PROBLEM TO BE SOLVED: To provide an imaging apparatus in which image correction is appropriately carried out regardless of image capturing modes. SOLUTION: Different gain correction signals (GSA, GSB) are used to correct imaging modes (motion image capturing mode/still image capturing mode) set to an X-ray imaging apparatus. In this way, even when imaging means whose gain characteristic is different between the motion image capturing mode and the still image capturing mode is used to constitute an X-ray imaging apparatus, it is possible to obtain images in which correction errors are reduced.
