Abstract:
A film image capturing method wherein image data is captured with a line sensor from each of a plurality of frames on a continuous developed film being transported at a preset speed and being illuminated with a light source, comprising:pre-scanning for determining exposed conditions of each of the plurality of frames on the film;index scanning for capturing rough image data from each of the plurality of frames on the film, wherein capturing conditions for each rough image data are adjusted according to the exposed conditions of the frame, and for producing an index image showing all or selected frames of the plurality of frames on the film; andmain scanning capturing fine image data from a desired frame of the plurality of frames on the film, wherein capturing conditions for each fine image data is adjusted according to the exposed conditions of the desired frame;wherein the index scanning is enabled before said light source reaches a predetermined stable state required for the main scanning such that the producing of the index image is performed at an early stage; andwherein, if the index scanning is performed before said light source reaches the stable state, thenrescanning is performed for determining the exposed conditions of each frame or the desired frame of the plurality of frames on the film after said light source reaches the stable state, andthe main scanning is performed wherein capturing conditions for each fine image data are adjusted according to the exposed conditions of the desired frame.
