A mammography apparatus (radiographic imaging apparatus) includes: a total irradiation time acquisition unit that acquires the total irradiation time of X-rays (radiation)； a divided irradiation time calculation unit that calculates a divided irradiation time by dividing the total irradiation time； an imaging controller that obtains a plurality of time-division images by time-division imaging in which radiographic imaging is performed multiple times according to the divided irradiation time； a feature point recognition unit that recognizes feature points for each of the time-division images； a time-division image selection unit that selects some or all of the time-division images from the plurality of time-division images using the feature points； and a composite image generation unit that generates a composite image using the selected time-division images.
