Claims
- 1. A photographic system comprising:
- a photographic camera, including:
- a camera body,
- a viewfinder,
- a user-operable shutter release,
- a camera lens for transmitting light from a subject external to the camera body onto a photographic film disposed inside the camera body to form an image of the subject on the photographic film,
- a first housing disposed in the camera body for housing a cartridge containing the photographic film,
- a second housing disposed in the camera body for housing the photographic film drawn from the cartridge,
- film drive means disposed in the camera body for driving the photographic film between the first and second housings and for automatically setting and loading the film,
- sensor means for optically detecting film position detecting holes and for generating a film position detecting signal based upon the film position detecting holes, wherein the film position detecting holes are 0.75 mm away from a first longitudinal edge of the photographic film,
- an exposure device for exposing the image of the subject onto a constant portion of an effective exposure area of the photographic film, the portion of the effective exposure area being located opposite an exposure opening between the first and second housings,
- user-operable selecting means for enabling a user to select one of a plurality of picture frame sizes, the plurality of picture frame sizes including frame sizes with different aspect ratios,
- recording means disposed in the camera body for recording on the photographic film an exposure information signal containing a first information based on a picture frame size selected using the user-operable selecting means and a second information related to the portion of the effective exposure area of the photographic film exposed by the exposure device, and
- control means including a micro-computer electrically connected to the sensor means and to the film drive means for controlling a position of the effective area in order to expose the image of the subject based upon the film position detecting signal, the control means controlling the recording means to record at least the exposure information signal on a longitudinal marginal area along a second longitudinal edge of the photographic film, wherein the marginal area is substantially 2.5 mm in film-width direction and is devoid of sprocket holes to allow recording of the exposure information signal; and
- a photographic printer for printing on a photosensitive paper a processed photographic film exposed using the photographic camera, the printer including:
- a printer body;
- film feeding means for feeding the processed photographic film in a predetermined direction,
- detecting means for non-mechanically detecting the exposure information signal recorded by the photographic camera in the longitudinal marginal area along the second longitudinal edge of the processed photographic film, wherein the information signal includes the first information and the second information, and wherein the longitudinal marginal area is a substantially 2.5 mm in film-width direction and is devoid of sprocket holes to allow recording of the exposure information signal,
- logic circuits means for determining whether an aspect ratio of a picture to be printed is of a first or a second frame format based on the first information of the exposure information signal and for determining the position of the image of the subject in the portion of the effective exposure area of the processed photographic film based on the second information of the exposure information signal, the logic circuits means distinguishing the print size control signal from other signals to avoid an error, and
- printing means for varying a width of an opening of a mask used to print the image of the subject in the effective exposure area of the processed photographic film onto the print paper based on the determined aspect ratio of the picture and for positioning the image of the subject in the effective exposure area of the processed photographic film within the opening of the mask based on the determined position of the image of the subject in the effective exposure area of the processed photographic film.
- 2. The photographic system according to claim 1, wherein the photographic printer further includes means for feeding the print paper for a length corresponding to an increase in the opening width at least when the opening width is increased.
- 3. The photographic system according to claim 1, wherein the logic circuit means receiving an output of the film feed sensor for determining that the detecting means correctly detected the picture aspect information.
- 4. The photographic system according to claim 1, wherein the holes are 1.0 mm in a diameter, and centers of the holes are 1.25 mm away from the longitudinal edge of the photographic film.
- 5. The photographic film printer system according to claim 1, wherein the second information indicates a center of the frame.
- 6. A photographic film printer system comprising:
- a printer body;
- film feeding means for feeding a processed photographic film in a predetermined direction, the leading edge of the film being shaped as a substantially straight line for splicing with each other without using a tongue-removing process;
- first means disposed on the printer body for generating a position control signal in response to a print frame control signal located along an edge of the photographic film, the print frame control signal relating to an exposed portion of an effective exposure area of the photographic film;
- second means disposed on the printer body for generating a print size control signal in response to picture aspect information located along the edge of the photographic film;
- logic circuits means for determining whether an aspect of a picture is of a first or a second frame format based on the print size control signal generated by the second means and for determining a frame of an image of a subject in the exposure portion of the effective exposure area of the photographic film based on the print frame control generated by the first means; and
- printing means disposed on the printer body for varying a width of an opening of a mask used to print the image of the subject in the effective exposure area of the photographic film onto photographic print paper based upon the determined frame format and for positioning the image of the subject in the effective exposure area of the photographic film within the opening of the mask, based on the determined frame of the image of the subject in the effective exposure area of the photographic film,
- wherein the exposure control signals indicates the area to be printed and the logic circuits means distinguishes the print size control signal from other signals to avoid an error.
- 7. The photographic film printer system according to claim 6, wherein the first means and the second means respectively include first and second sensing means arranged on the printer body in alignment with a marginal area of the photographic film.
- 8. The photographic film printer system according to claim 6, further comprising opening width control means for varying an opening width of a slit aligned with a path of the photographic film, the opening width of the slit being controlled in response to the print size control signal.
- 9. The photographic film printer system according to claim 6, further including means for feeding the print paper for a length corresponding to an increase in the opening width at least when the opening width is increased.
- 10. The photographic system according to claim 6, wherein the exposure position control signal indicates a center of the frame.
