PROBLEM TO BE SOLVED: To respectively record subject images having the same blur on silver salt film and a memory when a moving subject is photographed. SOLUTION: Based on the brightness of the subject and the sensitivity of the silver salt film, a diaphragm value and shutter speed with respect to the silver salt film are fixed at a point A. Based on the brightness of the subject and the sensitivity of an imaging device, the diaphragm value and the shutter speed with respect to the imaging device are fixed at a point B. In order to make the shutter speed equal, the diaphragm value and the shutter speed of the imaging device are fixed at a point C along a line L2.
