A radiographic apparatus which includes an X-ray irradiation unit which irradiates X-rays and an X-ray detection unit which detects an X-ray image of an object irradiated by the X-ray irradiation unit includes a first defect detection unit which detects, as a position-dependent defect, a pixel, of X-ray images, whose pixel value is always abnormal, and acquires position information of the defect in the X-ray image, a second defect detection unit which detects, as a defect, a pixel, of the X-ray images, which temporarily becomes abnormal dependent on the lapse of time, and a determination unit which determines a correction method for correcting the pixel value of the pixel in which the abnormality is detected by the second defect detection unit, based on the information indicating the imaging condition.
