An acquisition unit of a console acquires a first radiographic image and a second radiographic image. The first radiographic image and the second radiographic image are radiographic images which are output from a radiation detector by directing a radiation source to emit first radiation and second radiation in order to perform a moving image capture mode that continuously acquires a radiographic image required for the display of a moving image according to a preset frame interval. A receiving unit receives a request signal to request the generation of an energy subtraction image referred to for diagnosis. A generation unit generates the energy subtraction image in a case in which the receiving unit receives the request signal.
