Abstract: In the case where a radiation exposure dose of a human body that includes an artificial object is obtained based on a radiation image signal detected by a radiation image detector through the application of radiation transmitted through the human body, information of the artificial object included in the human body is obtained and, in the case where information indicating that an artificial object is included in the human body is obtained as the information of the artificial object, a correction is performed to increase the radiation exposure dose, which is based on the radiation image signal, by a predetermined correction radiation exposure dose.

Abstract: A radiation image capturing system includes a first image capturing apparatus for capturing a radiation image of a subject, a second image capturing apparatus for capturing a radiation image of the subject, the second image capturing apparatus having a specification different from that of the first image capturing apparatus, an image correcting device for correcting the radiation image of the subject which is captured by the second image capturing apparatus such that the radiation image of the subject which is captured by the second image capturing apparatus has the same magnification as that of the radiation image of the subject which is captured by the first image capturing apparatus, and a display unit for displaying the corrected radiation image. The radiation images captured by the image capturing apparatus of different specifications are corrected to have the same magnification.
