PROBLEM TO BE SOLVED: To improve performance of comparative image reading by appropriately performing comparative image reading when a radiographic image being an object of the comparative image reading includes non-recurrent unevenness in the density. SOLUTION: A radiographic image corrector includes: a data acquisition means for acquiring data which are similar in the unevenness in the density by using a pixel value in a prescribed region of the radiographic image with respect to each of two radiographic images obtained about an identical subject being the object of the comparative image reading; and a correction means for correcting the pixel value of either of two radiographic images so that the data which are similar in the unevenness in the density and are acquired from the corrected respective radiographic images by the data acquisition means coincide with one another on the basis of the data which are similar in the unevenness in the density and are acquired from the respective radiographic images by the data acquisition means.
