A dynamic radiographing system enables determination of an evaluation value of the heart function of a subject by plain radiography. The dynamic radiographing system comprises a radiographing apparatus, an image processing apparatus, and a console for diagnosis. The radiographing apparatus dynamically radiographs the heart of a subject and creates radiographs in plural time phases (Step S1). The image processing apparatus calculates an evaluation value of the heart function by using the radiographs in plural time phases (Step S4). The console for diagnosis displays information on the calculated evaluation value on the display section (Step S5).
