Abstract
A width of a illumination light being transmitted through a film is restricted within a distance between frames of the film. The film is transported to a position where only an area between frames is illuminated after the image of one frame is picked up, and a film transport is stopped. Then, the light is diminished or turned off when any operation is not instructed within a first time. Next, the film is transported in such a manner that a middle part of the frame is positioned below or above a photo detector when any operation is not instructed within a second time after the first time has passed, and the film transport is stopped. Then, a magnetic head is pressed against the film and the film is released from being held between the capstan and the pinch roller.
Claims20
A film image input method comprising the step of transporting a long developed photographic film including a plurality of frames;
- illuminating an image of each frame by a light source;
- picking up an illuminated image by a line sensor;
- and generating an output image signal by the line sensor, the method comprising the steps of:
- restricting a width of a illumination light of the light source which is transmitted through the film to be within a distance between frames of the film;
- transporting the film up to a position where only an area between frames of the film is illuminated after the image of one frame is picked up by the line sensor;
- and
- stopping a film transport.
A film image input method comprising the step of transporting a long developed photographic film which is held between a capstan and a pinch roller, the film including a plurality of frames;
- illuminating an image of each frame by a light source;
- picking up an illuminated image by a line sensor;
- and generating an output image signal by the line sensor, the method comprising the steps of:
- transporting one of a forward end part of the film or a rear end part of the film where there is no frame up to a pickup position where the line sensor picks up the image on the film in the case when a predetermined operation is not instructed within a first time after the image of one frame is picked up by the line sensor;
- and
- releasing the film from being held between the capstan and the pinch roller after one of the forward end or the rear end of the film is transported up to the pickup position.
A film image input method comprising the step of transporting a long developed photographic film which is held between a capstan and a pinch roller, the film including a plurality of frames, a perforation being provided for each frame;
- illuminating an image on each of the frames by a light source;
- detecting the perforation by means of a perforation detecting means;
- picking up an illuminated image by a line sensor in accordance with a detection of the perforation;
- and generating an output image signal by the line sensor, the method comprising the steps of:
- transporting a middle part of the frame up to a vicinity of the perforation detecting means in the case that a predetermined operation is not instructed within a first time after the image of one frame is picked up by the line sensor;
- stopping a film transport;
- and
- releasing the film from being held between the capstan and the pinch roller.
A film image input method comprising the step of transporting a long developed photographic including a plurality of frames;
- illuminating an image of each frame by a light source;
- picking up an illuminated image by a line sensor;
- and generating an output image signal by the line sensor, the method comprising the steps of:
- moving the photographic film continuously within one frame at a low speed in the case when a predetermined operation is not instructed within a first time after the image of one frame is picked up by the line sensor in order to prevent an illumination position from concentrating at one position.
