A radiographic apparatus, comprises a generating unit that generates a composite image using a plurality of radiographic images that have been obtained by a plurality of radiation detecting apparatuses through single radiation irradiation by a radiation generating unit, a determining unit that determines a region to be analyzed so as to eliminate an overlap in an overlapping portion arising from a spatial placement of the plurality of radiation detecting apparatuses, and an obtaining unit that obtains an area dose for the composite image by obtaining an area dose for the region to be analyzed determined by the determining unit.
