A radiation imaging system which captures a radiographic image obtains examination information including the patient information of a patient as a target for the imaging and imaging information defining the contents of imaging executed for the patient, controls the radiation imaging of a patient in accordance with the examination information, stores the captured radiographic image in association with the patient information of the image, and switches and displays, within one window, an imaging screen used for imaging based on the examination information and a playback screen used for playback of the stored radiographic image. The apparatus then detects a switching instruction for display of a displayed screen based on input operation by an operator, compares patient information corresponding to the imaging screen with patient information corresponding to the playback screen when display switching is performed based on the switching instruction, and notifies the operator of the comparison result.
