Abstract: A derivation unit derives imaging conditions corresponding to virtual grid characteristics (grid ratio) received by a receiving unit on the basis of a table stored in a storage unit. The derivation unit sets the derived imaging conditions in a radiation source control unit. The radiation source control unit controls a radiation source on the basis of the set imaging conditions such that a radiographic image is captured. An execution unit of an image processing device acquires the radiographic image captured by the radiation detector through a detector control unit. The execution unit performs a virtual grid process for the acquired radiographic image on the basis of the virtual grid characteristics received by the receiving unit and the imaging conditions derived by the derivation unit to generate a radiographic image from which the influence of scattered radiation has been removed and displays the radiographic image on a display unit.

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: The present invention is capable of reducing a load of a processing operation of a user. Namely, a console first acquires an original image of a radiographic image acquired from a radiographic image capturing device, in order to perform common processing operations. The console detects common processing operations performed on an original image by the user and stores processing content of the common processing operations and the original image in association with each other. In a case in which processing transitions to individual processing (purpose A) for generating a purpose A image, the console performs image analysis process A on the acquired original image and reflects the common processing to generate an image for purpose A. Further, the console detects individual processing operations performed on the image for purpose A by the user, and performs image processing corresponding to the individual processing operations to generate a purpose A image.
