Summary:PROBLEM TO BE SOLVED: To suppress an exposure dosage and to achieve uniform density of each radiation image in radiography that obtains a long radiation image by photographing the radiation image in each region while sequentially moving a radiation detector to multiple regions adjoining to a subject.SOLUTION: In performing radiography of each region N1, N2, ..., visible light image of each region N1, N2, ... is photographed, a photographed portion of the subject N included in the visible light image is recognized, a radiation dose of a radiation source is set so that concentration of each radiation image is uniform based on a recognized result of the photographed portion, and the radiation image of each region N1, N2, ... is synthesized so as to generate the long radiation image exhibiting the entire subject N.
