PROBLEM TO BE SOLVED: To detect a body movement included in a radiation image with good accuracy regardless of an image capturing condition and a subject.SOLUTION: A contrast calculating part 24 calculates a contrast of a high frequency component and a contrast a low frequency component of a converted radiation image G0 at an analysis point set by an analysis point setting part 23. A ratio calculating part 25 calculates a ratio of the contrast of the high frequency component to the contrast of the low frequency component. A determination part 26 determines whether or not a body movement exists in capturing a radiation image G0 on the basis of the ratio. A display control part 27 displays the determination result on a display part 40. |
