An object is to enhance usability of parameter check when an imaging parameter is changed in multistation imaging, and easily obtain a desired image with high quality. In the multistation imaging, it is determined in a lump before imaging whether an image having desired quality is obtained by using the changed value of the imaging parameter, and the result is presented to an operator. The determination is executed in the order of “possible or impossible” determination of execution of imaging itself and “possible or impossible” determination of combination of obtained images. When it is determined that it is impossible to execute the imaging itself, the determination processing is finished. At this time, a recommended value may be presented.
