[0007]

The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a block diagram of a camera system showing an embodiment of the present invention. The light flux from the subject that has passed through the front lens group 1 disposed on the front side of the subject side passes through the beam splitter 2 disposed behind the front lens group 1 and on the optical axis 0 of the photographing optical system. To reach. The beam splitter 2 directs a light beam from a subject to the direction of the optical axis 0 of the photographing optical system.
It serves to divide the light into a direction in which the light is reflected upward perpendicularly to the optical axis 0. A part of the light flux from the subject passes through the beam splitter 2 and travels straight in the optical axis direction, while the rest of the light flux is reflected above the splitter 2 toward a mirror 7 inclined at 45 degrees. .

The transmitted light flux passes through the diaphragm 3 disposed behind the beam splitter 2 and the diaphragm 3
The light passes through the rear lens group 4 disposed behind the rear lens group 4 and reaches the shutter 5 disposed behind the rear lens group 4. Immediately after the shutter 5, the silver salt film 6
Is provided. Therefore, the front lens group 1, the beam splitter 2, and the rear lens group 4 compose a photographing optical system for the silver salt film 6, and the release switch 2 of the camera.
When 0 is pressed to open the shutter 5, the shutter 5
The above-mentioned silver salt film 6 stretched behind is exposed.

Here, the following film is used as the silver salt film 6. That is, as shown in FIG. 3, the silver salt film 6 is a magnetic film 4 made of a magnetic recording medium for magnetically recording processing information at the time of printing in a strip shape along the longitudinal direction of the film on the upper end of the back surface thereof.
0 is attached.

On the other hand, as shown in FIG. 1, the light beam reflected upward by the beam splitter 2 is reflected backward by the mirror 7 and transmitted through a relay lens 8 arranged behind the mirror 7. CC passing through the infrared cut filter 25 arranged behind the relay lens 8 and arranged behind the infrared cut filter 25.
It is irradiated to D9. Therefore, the front lens group 1, the beam splitter 2, the mirror 7, the relay lens 8, the infrared cut filter 25, and the CCD 9 constitute an electronic image photographing optical system.

The output of the CCD 9 is amplified by the preamplifier 10 and input to the process circuit 11. In this process circuit, various processes such as gamma correction and gain adjustment are performed and converted into an analog video signal. This analog video signal is converted into a digital video signal by the A / D converter 12. This digital video signal is synchronized with the depression of the release switch 20 by a video RAM (random access memory) 1 by an address signal corresponding to the number of film frames from a sequence controller 22 for controlling the sequence of the entire camera.
3 is stored. The digital video signal stored in the video RAM 13 is the same as the sequence controller 2 described above.
The LCD driver 14 is designated by the address signal from 2
Entered in. The liquid crystal drive signal of the digital video signal is output from the liquid crystal driver 14, and the image of the digital video signal is displayed on the liquid crystal screen 15. While observing the image displayed on the liquid crystal screen 15, the sequence information is provided by the print information writing means 16 at the appropriate time by using the print information writing means 16 to obtain the process information such as the number of prints of the image and the trimming range.
The processing information at the time of printing such as the number of prints and the trimming range which are input to the sequence controller 22 are stored in the print information storage means 17 including a RAM.

A signal is input to the sequence controller 22 from the film rewinding switch 21 in addition to the release switch 20. That is, when the film rewinding switch 21 is closed,
This signal is input to the sequence controller 22, and the output signal from the sequence controller 22 is input to the motor driver 24. The motor driver 24 rotates the film driving motor 23 provided in the camera body in the rewinding direction to rewind the silver salt film 6.

The magnetic film 40 attached to the silver salt film 6 is provided with the magnetic head 18 for recording the print information and the magnetic head 26 for detecting the synchronization signal, respectively. The print information recording magnetic head 18 and the sync signal detecting magnetic head 26 are connected to the sequence controller 22, respectively. The magnetic head 26 for detecting the synchronizing signal
Has a role of detecting a synchronization signal previously recorded on the magnetic film 40 of the silver salt film 6 when the silver salt film 6 is rewound. The print information storage is synchronized with the synchronization signal. The processing information at the time of printing such as the number of prints and the trimming range stored in the means 17 is written on the magnetic film 40 by the print information recording magnetic head 18. If the print information stored in the print information storage means 17 is not recorded in the magnetic film 40, it is stored in the IC card 19.

Next, the operation of the camera system thus configured will be described. When the photographer depresses the release button, the release switch 20 is closed, and the exposure control means (not shown in detail in the present embodiment) is actuated to determine an appropriate exposure factor to determine the shutter 5.
Is opened, and the silver salt film 6 is exposed. Further, in synchronization with the exposure operation of the silver salt film 6, the light flux of the same subject exposed on the silver salt film 6 is changed to the CC.
It is irradiated to D9.

Therefore, the CCD 9 is charged with electric charges according to the irradiated light flux, and outputs a scanned image signal. The image signal output from the CCD 9 is input to the preamplifier 10 and amplified, and then input to the process circuit 11. Here, various correction processes such as gamma correction and gain adjustment are performed and converted into an analog video signal. This analog video signal is the above A / D
The digital video signal is A / D converted by the converter 12 and output to the video RAM 13. The data of the digital video signal input to the video RAM 13 is stored in a memory address specified by an address signal from the sequence controller 22 according to the number of film frames.

Incidentally, FIG. 4 shows a state in which the data of the digital video signal is stored in the video RAM 13. The video RAM 13 stores the data of the digital video signal for each number of shooting frames, and when the number of shooting frames is designated, the digital video signal of the number of frames can be called.

This digital video signal is the same video RAM
At the same time as being stored in the video RAM 13, the same digital video signal stored in the video RAM 13 is output to the liquid crystal driver 14 by the same address signal from the sequence controller 22. The same image as the subject that was exposed to
It is displayed on the liquid crystal screen 15 in real time. Therefore,
Thereby, the image photographed on the silver salt film 6 can be confirmed.

When the above operations are repeated and the required number of images have been taken, the processing information for printing is then written.
This is done as follows. That is, the print information writing means 16 inputs the address of the number of frames to which the processing information at the time of printing is written to the sequence controller 22. Then, the sequence controller 22 outputs an address signal corresponding to the number of film frames to the video RAM 13, and a digital video signal which is data stored in the memory address of the address signal is output to the liquid crystal driver 14. Then, the image of the number of photographed frames is displayed on the liquid crystal screen 15. While confirming the image displayed on the liquid crystal screen 15, the photographer inputs the processing information at the time of printing such as the number of prints of the image and the trimming range from the print information writing means 16 to the sequence controller 22. It is stored in the print information storage means 17.

Here, the trimming information written as the processing information at the time of printing will be described. The trimming information specifies the trimming range as shown in FIG. For example, on the liquid crystal screen 15, the XY coordinates of two points on the diagonal of the trimming range are associated with the XY coordinates.
The coordinate display is the trimming information of the trimming range. In FIG. 6, all coordinates on the LCD screen are 1 to 1 in the X direction.
3, the Y direction is divided into 1 to 9, and the coordinates of the trimming range shown are (3, 2), (12, 8).
Becomes Therefore, as the data of the trimming range, four numbers {3, 2, 12, 8} may be sequentially input.

FIG. 5 shows a state in which the number of prints and trimming information, which are processing information at the time of printing, are stored in the print information storage unit 17. In this way, the print information storage means 17 stores the data of the desired number of prints and the data of the trimming information with respect to the number of film frames.

After the necessary print information for the number of frames taken has been stored in the print information storage means 17 in this manner, the print information data stored in the print information storage means 17 is converted to the silver salt film 6 described above. The above-mentioned magnetic film 40 is recorded. This recording operation is automatically performed by the magnetic heads 18 and 26 by rewinding the film. That is, the film rewind switch 2
When 2 is closed, a film rewind signal is output from the sequence controller 22 to the motor driver 24, and the motor driver 24 rotates the film driving motor 23 in the rewind direction. When the rewinding of the film is started, the sync signal previously magnetically recorded on the magnetic film 40 of the silver salt film 6 is detected by the sync signal detecting head 26. Then, the print information for each number of frames stored in the print information storage means 17 is output to the print information recording magnetic head 18 in synchronization with the synchronization signal, and the magnetic film 40 of the silver salt film 6 is output. To record.

FIG. 2 shows the correspondence between the print information recording portion of the magnetic film 40 of the silver salt film 6, the sync signal detecting magnetic head 26, and the print information recording magnetic head 18. A sync signal is recorded on the sync signal track 30 on the outer side of the magnetic film 40, and the sync signal is detected by the sync signal detecting magnetic head 26. The sync signal is amplified by the sync signal amplifier 31 and input to the sequence controller 22. The print information output from the sequence controller 22 is the print information signal amplifier 3
Amplified by 3 and output to the print information recording magnetic head 18, and is recorded on the print information recording track 32 inside the magnetic film 40 in synchronization with the synchronizing signal by the print magnetic head 18.

In the above embodiment, the processing information at the time of printing is stored in the print information storage means 17 after the photographing for all the film frames is finished. Each time the subject image is exposed on the silver salt film 6 and at the same time, the same subject image is displayed on the liquid crystal screen 15, the image is confirmed, and the printing process information such as the number of prints and the print range is printed. Information may be input to the sequence controller from the information writing unit 16 and stored in the print information storage unit 17. The print information does not necessarily have to be recorded on the magnetic film 40 on the silver salt film 6, but may be stored on the IC card 19.

The silver salt film in which the print information is written in this way is automatically printed by the information in the laboratory.

[0025]

As described above, according to the present invention, the same subject as the subject exposed on the silver salt film can be stored in the electronic image storage means and displayed as an electronic image. While checking the electronic image, it is possible to specify the print processing information such as the number of prints and trimming information. For this reason, the troublesome work of designating the processing information at the time of printing such as the number of prints and the trimming range after performing the printing once and confirming as before is not necessary, and the processing can be performed faster and without waste. You can finish the print.
