A photo film, which is hard and has a little winding peculiarity and which is excellent in dynamic intensity, is used, whereby film feeding problems, which easily occur when a line sensor is used, are reduced. A long roll of a developed photo film for still photography, which is loaded between a feeding side and a winding side, is fed at a constant speed between the feeding side and the winding side, so that the image data are taken in through a line sensor. Before taking in the image data of the desired frame, first, a taking environment such as a brightness and a white balance of every frame is detected during the first feeding of the photo film. And, when one frame is reproduced, the image data of the desired frame are taken in through the line sensor during the second feeding of the photo film, and further, an exposure, a white balance and the like are adjusted in accordance with the detected taking environment of said frame when the image data are taken in. The base of the photo film used in the film image input method is poly-ethylene-naphthalate, and more preferably, is heat treated at more than 50 DEG C. and less than the glass transition temperature for 0.1-1500 hours.
