Abstract: It is detected whether a grid stripe is present in a radiographic image. In a case in which the grid stripe is detected, a process of removing the grid stripe from the radiographic image is performed and the radiographic image is displayed. In a case in which the grid stripe is not detected, a process of removing a scattered component from the radiographic image is performed and a radiographic image subjected to the scattered radiation removal process and a radiographic image before the process are displayed.

Abstract: A radiographic image captured by irradiating a subject with radiation is acquired. A scattered radiation removal unit removes a scattered component from the radiographic image using at least imaging conditions. A correction information acquisition unit acquires correction information for correcting the degree of removal of the scattered component and changes the imaging conditions on the basis of the correction information. The scattered radiation removal unit performs a process of removing the scattered component from the radiographic image on the basis of the changed imaging conditions.
