Next, the operation of the present embodiment will be described. FIG.
As shown in (A), the photographer sets the finder optical system 19
To determine the shooting range. At this time, since the viewfinder optical system 19 has a view range of 12% (area ratio) of the exposure range 44, the subject image observed from the eyepiece viewfinder window 10 is twice as large as usual. Then, framing is performed, and the release button 7 is pressed to perform photographing.

The used lens-equipped film unit 2 is sent to a developing station as it is, and the cartridge case 33 containing the exposed film is taken out of the lens-equipped film unit 2 and the film is developed. Then, for example, in a print process in a minilab, the photographic film 23 after the film development process is wound into a print process cartridge 58. At this time, image data is read from each photographed frame (pre-scan), PAR
The bits and magnetic recording data are read and stored in the memory 56. The prescanned image data is used for index printing.

At the time of print processing, fine scan is performed one frame at a time from the photo film 23 pulled out from the print processing cartridge. Then, the frame number is read by the magnetic head 52. The frame number is output to the controller 59, and the PAR bit data and the magnetic recording data of the corresponding photographing frame are read from the memory 56. Further, the photographed frame subjected to the fine scan is taken up by the original cartridge case 33. At this time, three PAR bits 46 are read from the optical mark area 45.

The image data recorded in the image memory 55 is read out by the image processing circuit 57, and image processing is performed based on the corresponding PAR bit data and magnetic recording data. That is, as shown in FIG. 6B, in the case of the present embodiment, since three PAR bits are imprinted, the range of 露 光 of the exposure range 44 is The print range 66 is determined. The processed image data is sent to the image memory 60 and is exposed on a C-size color photographic paper 65. As a result, as shown in FIG. 6C, a double enlarged print photograph is created.

In the above-described embodiment, three optical marks are printed in the optical mark area in advance, and when the optical marks are detected, a print range is selected and an enlarged print photograph is created at an arbitrary enlargement magnification. Data indicating that the print is double-magnified may be magnetically recorded. As shown in FIG. 5, the magnetic recording layer of the photographic film 70 used for the APS has a plurality of magnetic recording areas. The magnetic recording area includes an area 71 for recording shooting information of each frame such as an aperture value, an area 72 for recording image processing information in a laboratory, and the like. Magnetic recording area 73 for recording type information arranged in the leader of photo film 70
Then, data indicating double telephoto shooting is magnetically recorded in advance. Thus, by reading the magnetic recording area 73 after the development processing of the used photographic film, the enlarged print is performed at a magnification twice as large as that of the standard print. Note that magnetic recording may be performed in a magnetic recording area indicated by reference numeral 74.

In the above embodiment, the enlargement ratio of the enlarged print photograph is doubled. However, the enlargement ratio does not need to be limited to two times, and may be set to an arbitrary magnification between two and three times. Good. In this case, it is necessary to set the finder magnification corresponding to the enlargement magnification.

With a viewfinder with a viewfinder magnification set so that the center of the shooting range formed in the effective exposure range of the photo film is the center of the viewing range, and the viewing range is the printing range for enlarged printing Since an indication that telephoto shooting is to be performed is provided on the exterior of the film unit, an enlarged print can be obtained at low cost even with a lens-fitted film unit.

When a photographic print is made from a photographic film taken by the film unit with a lens,
Enlarged print identification marks exposed in the mark exposure area are detected, and enlarged prints are performed at a magnification corresponding to the ratio between the photographing range and the visual field range. Therefore, enlarged prints can be performed without changing the structure of the conventional printing device. It is possible to automatically recognize that there is, and it is possible to perform enlarged printing at high speed.

Further, a method is pre-recorded on the magnetic recording layer formed on the photographic film, which indicates that the printing range at the time of printing is different from the standard printing range, and automatically reads the information at the time of printing. However, enlarged prints can be obtained at low cost.
