A compression plate of a mammography apparatus has an upper surface which is irradiated with radiation, a lower surface which is opposite to the upper surface and comes into contact with the breast, and a surface which is parallel to the upper surface between the upper surface and the lower surface. In the compression plate, a compression plate scale for identifying an in-plane position of each surface is given to any one of the surfaces. A first display control unit of a console performs control to display a radiographic image captured by the mammography apparatus on a display unit. A second display control unit of the console performs control to display an image scale which indicates a position on the radiographic image corresponding to the in-plane position of the compression plate on the radiographic image displayed on the display unit.
