PROBLEM TO BE SOLVED: To provide a radiation image photographing device that is suitable to high-speed moving picture photographing like fluoroscopy and angiography by preventing image quality deterioration caused by an artifact, that is, an after image resulting from a response characteristic of a fluorescent substance or photoelectric converting element. SOLUTION: To solve the above problem, this radiation image photographing device has an operating state detecting means and an after image correcting means. Further, a photographing condition detecting means detects operating states, such as endurance time, environmental temperature, X-ray energy and a sensor bias, determines an optimal after image correction parameter from a predefined LUT or the like in accordance with the detected operating states and corrects an image output.
