Between the image pickup section and the film rewinding section,
A film encoder 10, a reproducing magnetic head MH1, a recording magnetic head MH2, and an optical reading device 11 are provided. The film encoder 10 is rotated by being driven by the guide roller 10a that rotates with the feeding of the film 3, and generates a pulse signal for each predetermined film feeding amount. By counting the pulse signals generated by the film encoder 10, the feeding amount and feeding speed of the film 3 can be detected, and the feeding control of the film 3 is performed based on the detected feeding amount. The reproducing head MH1 is a magnetic head for reproducing magnetic information previously recorded in the magnetic recording portion 3b of the film 3, and is brought into contact with the film 3 at the start of reproducing magnetic data by a mechanism (not shown), and at the end of reproducing the film. Evacuated from 3. The recording head MH2 is a magnetic head for recording various information in the magnetic recording unit 3b, and is brought into contact with the film 3 at the start of recording magnetic data by a mechanism (not shown) and retracted from the film 3 at the end of recording. Further, the optical reading device 11 reads the information optically recorded on the film 3. In this embodiment, an example in which the reproducing head and the recording head are provided separately is shown, but a recording / reproducing head may be used. A magnetic head for recording and reproducing is also installed in the magnetic recording portion 3c between the perforations 3a. Photo interrupters PH1 and PH2 for detecting the perforations 3a of the film 3 are provided before and after the aperture 5 in the film feeding direction. The positional relationship between the filmed frames and the perforations of the film 3 is set to be the same for all frames. In this embodiment, in the feeding control of the film 3 based on the film feeding amount detected by the film encoder 10. , Photointerrupter P
Positioning control of each shooting frame with respect to the aperture 5 is performed based on the detection result of perforation by H1 and PH2.

In FIG. 2, a microcomputer 20 is composed of a CPU and its peripheral parts, and executes a control program described later to execute film feeding control, image pickup control, video reproduction control, magnetic information reproduction / recording control, etc. Do. The microcomputer 20 has the above-mentioned CCD
9, the image pickup circuit 21, and the video control circuit 22 are connected. The image pickup circuit 21 converts the image signal read by the CCD 9 into a video signal, and the video control circuit 22 processes the video signal and reproduces the image on the video monitor 23 via the terminal 23a. Although the video monitor 23 may be built in the film image display apparatus 1, a home television receiver is usually used as the video monitor.

The microcomputer 20 is also connected to various switches SW1 to SW11, the film encoder 10, the optical reading device 11, and the photo interrupters PH1 and PH2 described above. The switch SW1 is a switch for detecting the developed state of the film 3, the switch SW2 is a power switch, the switch SW3 is a cartridge loading detection switch for the cartridge chamber, and the switch SW4 is an opening detection switch for the cartridge chamber cover (not shown). is there. Further, the switches SW5 to SW10 are operation switches for film feeding, SW5 is a one-frame feed switch, SW6 is a one-frame return switch, SW7 is an index mode switch, SW8 is a frame designation mode switch,
SW9 is a skip mode switch, and SW10 is a rewind switch. Further, the switch SW11 is an eject switch for ejecting the cartridge 2 from the cartridge chamber. In this specification, the term "one frame feed" or simply "frame feed" refers to the operation of winding the film 3 from the film cartridge 2 onto the winding spool 4 of the film image display device 1 one frame at a time. The microcomputer 20 further includes drivers DR1 to DR that drive the motors M1 to M4, respectively.
4, a reproducing circuit 24 for driving the reproducing head MH1, a recording circuit 25 for driving the recording head MH2, a warning buzzer Bz, a memory 26, and an input device 27 for inputting a frame number and the like.

5 to 18 are flowcharts showing the processing of the microcomputer 20. The operation of the embodiment will be described with reference to these flowcharts. Figure 5
FIG. 7 is a flowchart showing the main processing. When the power switch SW2 is turned on in step 101, the process is started, and in step 102, the initialization routine shown in FIG. 8 is executed to initialize each part.

In step 201 of FIG. 8, a reset operation is performed when the power of each control circuit and each device is turned on.
In the following step 202, it is determined by the switch SW3 whether or not the cartridge 2 is loaded in the cartridge chamber of the film image display apparatus 1. If the cartridge 2 is loaded, the process proceeds to step 203. After the image is displayed on the film image display device 1, the power may be turned off without taking out the cartridge 2 from the device 1. In that case, it is considered that the film information of the cartridge 2 is reproduced and stored in the memory 26 at the time of the previous image display. Therefore, when the power is turned on again with the cartridge 2 loaded, the information reproduction and storage operation is performed again. You don't have to. Therefore, if the cartridge 2 is already loaded when the power is turned on, the memory 26 is loaded in step 203.
The information of the cartridge 2 that is more loaded is extracted.
This information includes information including the IS0 sensitivity optically recorded on the surface of the cartridge 2 and the number of films, and the information about shooting recorded for the leader portion of the film 3 and each shooting frame. When the above process is completed, the process returns to step 103 in FIG.

In step 103 after the return, if the cartridge 2 is not loaded, a message prompting the loading of the cartridge 2, such as "please load the cartridge", is displayed on the video monitor 23. Also, if a cartridge 2 is loaded, information about the loaded cartridge 2 and a message about the operation to be performed after this, for example, "The cartridge is already loaded. ◯◯◯◯. When the cartridge is taken out, the eject button is displayed, and when the operation is continued, the operation is selected. Here, the information regarding the loaded cartridge is the one extracted from the memory 26 in step 203 of FIG. In step 104, power switch SW
It is reconfirmed whether or not 2 has been input. If it has been input, the process proceeds to step 105, and if it has not been input, the process ends. In step 105, the eject switch S
The state of W11 is confirmed. If the eject switch SW11 is operated, the process proceeds to step 106, and if not, the process proceeds to step 105A. When the eject switch SW11 is not operated, it is confirmed in step 105A whether or not the cartridge 2 is loaded. If the cartridge 2 is loaded, the process proceeds to step 125 to wait for the next operation input, and if the cartridge 2 is not loaded, the process proceeds to step 105B to display the operation message "please load the cartridge" on the video monitor 23. , Return to step 104. That is, here, in a state where the eject switch SW11 is not operated and the cartridge 2 is not loaded, the state of waiting for the operation of the eject switch SW11 is continued while displaying a message prompting the loading of the cartridge 2. .. On the other hand, with the cartridge 2 loaded,
The eject switch SW11 is operated or the next operation input waiting state is continued. When the eject switch SW11 is operated while the power switch SW2 is turned on, it is confirmed in step 106 whether or not the cartridge 2 is loaded. If the cartridge 2 is loaded, the process proceeds to step 106A, and if the cartridge 2 is not loaded, the step 1 is performed.
Proceed to 06D. When the eject switch SW11 is operated while the cartridge 2 is loaded, the film 3 of the loaded cartridge 2 is loaded in step 106A.
Check if is rewound. When the film 3 is not rewound into the cartridge 2, step 106B
Film DR3 by driver DR1 and motor M1
Is rewound into the cartridge 2. In step 106C, the display mechanism 2c of the cartridge 2 described above is set to "developed" by an actuator (not shown). This is to prevent the developed cartridge from being accidentally loaded into the camera. In step 106D, the cartridge chamber lid is opened by an actuator (not shown). A mechanism that prevents the lid of the cartridge chamber from being opened carelessly may be provided so that the mechanism is released when the cartridge is ejected. In step 107, it is confirmed by the switch SW4 whether or not the lid of the cartridge chamber is closed. With respect to the cartridge chamber lid, the lid may be automatically closed in conjunction with the operation of the eject switch SW11, or a cartridge chamber lid closing switch may be provided and closed manually. Step 1 if the lid of the cartridge chamber is closed
08, and if not closed, it proceeds to step 107A. In step 107A, the timer is started, and in the following step 107B, it is confirmed whether the timer has timed out. When the time is not up, the process returns to step 107, and the waiting state for the closing operation of the cartridge chamber lid is continued for a certain time. On the other hand, even when the time is up, if the cartridge chamber lid is not closed, the routine proceeds to step 107C, where the actuator (not shown) forcibly closes the cartridge chamber lid. However, if the cartridge chamber lid is not opened and closed by the actuator, it is opened and closed manually. In step 108, it is confirmed whether or not the cartridge 2 is loaded. When the cartridge 2 is not loaded, the process returns to step 104, and when it is loaded, the process proceeds to step 109.

When the cartridge 2 is loaded in the cartridge chamber, the switch SW1 is used to confirm whether or not the development is completed in step 109. If the development is completed in the subsequent step 110, the process proceeds to step 113. If the development is not completed, Go to step 111. If the loaded cartridge 2 has not been developed, the buzzer Bz is sounded in step 111 to warn, and in the subsequent step 112, the operation for ejecting the cartridge is performed. For example, an actuator opens the lid of the cartridge chamber so that the cartridge 2 can be taken out. If the developed cartridge 2 is loaded, the driver DR2 is controlled in step 113 to drive the motor M2 to open the cartridge door 2d. In the following step 114, the cartridge 2
Film data such as ISO sensitivity and the number of films recorded on the surface of the sheet is read by a reading device (not shown) and stored in the memory 26.

In step 115 of FIG. 6, the driver DR1 is controlled to drive the motor M1 to feed the film 3 out of the cartridge 2. In step 116, the optical reading device 11 starts reading the optical data recorded on the film 3, and in the following step 117, the reproducing head MH1 is brought into contact with the film 3 and the reproducing circuit 24 starts reproducing the magnetic data. Usually, in the leader portion of the film 3, the cartridge loading direction information of the camera and the like are recorded in an optical or magnetic recording form, and the reading of these data is started when the feeding of the film 3 is started. The magnetic data recorded in the magnetic recording portion 3b of the first frame of the film 3 is also read when the film is fed. In step 118, detection of perforation is started by the photo interrupters PH1 and PH2. In step 119, it is determined whether or not the first frame of the film 3 is set at the image pickup position, that is, a predetermined position facing the aperture 5, based on the perforation detection result detected by the photo interrupters PH1 and PH2. When the frame is set to the image pickup position, the process proceeds to step 120, where the driver DR1 is controlled to stop the motor M1 and the feeding of the film 3 is stopped.
Further, the reproducing head MH1 is retracted to end the input of magnetic data by the reproducing circuit 24 and the input of optical data by the optical reading device 11. In setting the first frame, the motor M3 may be driven in accordance with the feeding of the film 3 by the motor M1, and the film 3 may be wound up. Even in this case, both motors M1 and M3 are stopped according to the setting of the first frame.

In step 121, the optical data processing routine shown in FIG. 9 is executed to process the optical data read by the optical reading device 11. In step 210 of FIG. 9, it is determined whether or not the loading direction information of the camera is detected. If the loading direction information is detected, the process proceeds to step 211. If the loading direction information is not detected, the process proceeds to step 212. In this embodiment, a camera having a cartridge chamber on the right side and a film winding spool on the left side when the camera is viewed from the back side is a standard camera. When viewed from the back of the camera, there is a cartridge chamber on the left side and a film winding spool on the right side. Filmed with a non-standard camera The leader of the film was optically or magnetically filmed with a non-standard camera. It is assumed that the loading direction information indicating is recorded. If an image of the film on which such loading direction information is recorded is taken as it is, the video monitor 23
Since the upside down image is played back in, step 21
At 1, the upside down process is performed. In this vertical inversion processing, for example, the CCD 9 may be rotated 180 degrees to mechanically perform the vertical inversion of the image, or the image pickup lens 8 may optically perform the vertical inversion of the image. Alternatively, the image may be digitally processed and vertically inverted. Next, in step 212, film-specific information such as ISO sensitivity, film type, and number of films is extracted from the read optical data and stored in the memory 26. The color of the image can be corrected based on this information. Further, in step 213, roll information such as shooting content recorded by the photographer is extracted from the optical data and stored in the memory 26.

Next, in step 122 of FIG.
The magnetic data processing indicated by 0 is performed to process the magnetic data reproduced by the reproducing circuit 24 and the reproducing head MH1. In step 220 of FIG. 10, it is determined whether or not the magnetic data is recorded in the leader portion of the film 3, and if the magnetic data is recorded, the process proceeds to step 221, and if the magnetic data is not recorded, the process proceeds to step 225. . When the magnetic data is recorded in the leader portion of the film 3, it is determined in step 221 whether or not the loading direction information indicating the film taken by the non-standard camera is detected. If the loading direction information is detected, the process proceeds to step 222. If the loading direction information is not detected, the process proceeds to step 223. When the loading direction information is detected, the image is turned upside down by the method described above in step 222.
In step 223, the magnetic data recorded in the leader portion of the film 3 is extracted, and in step 224, the magnetic data of the leader portion extracted is stored in the memory 26. In step 225, the magnetic data of the first frame read at the time of feeding the film is stored in the memory 26. When the processing of the optical data and the magnetic data is completed, step 12 in FIG.
3, the data to be displayed is generated based on the data read at the time of film feeding, and the following step 12
The display data generated in 4 is displayed on the video monitor 23. As described above, during the initial feeding process by feeding the film from the cartridge 2, the feeding control is performed so that the first frame faces the image pickup unit, and in response to this operation, the first frame of the film 3 and The information recorded magnetically or optically in the reader unit is reproduced, and the reproduced information of the first frame and / or the reader unit is displayed without displaying the image of the first frame set by the initial feeding. Therefore, the information of the film 3 can be displayed in advance before the feeding mode of the loaded film cartridge is selected.

Next, in step 125 of FIG.
The feed mode determination routine shown in 1 is executed, and the switch S
The feeding mode set by W5 to SW10 is determined. In step 301 of FIG. 11, it is determined whether or not the one-frame feed switch SW5 is operated. When the one-frame feed switch SW5 is operated, the process proceeds to step 302 to set the one-frame feed mode. In step 303, it is determined whether or not the one-frame return switch SW6 is operated, and 1
Step 3 when the piece return switch SW6 is operated
Proceed to 04 to set the one-frame return mode. Step 30
In step 5, it is determined whether the index mode switch SW7 is operated, and the index mode switch SW7 is operated.
When is operated, the process proceeds to step 306 to set the index mode. The index mode is a mode in which the information of all pieces is first fetched and displayed. In step 307, it is determined whether or not the piece designation mode switch SW8 is operated, and the piece designation mode switch S
When W8 is operated, the process proceeds to step 308 to set the piece designation mode. The piece designation mode is a mode for displaying an arbitrary piece designated by the user. In step 309, it is determined whether or not the skip mode switch SW9 is operated, and when the skip mode switch SW9 is operated, the process proceeds to step 310 to set the skip mode. The skip mode is a mode in which frames are displayed one by one for a certain period of time. In addition, step 3
At 11, it is determined whether or not the rewind switch SW10 is operated. When the rewind switch SW10 is operated, the process proceeds to step 312 to set the rewind mode. In step 313, the set feeding mode is displayed on the video monitor 23, and the process returns to step 126 in FIG. 7.

In this embodiment, the dedicated operation switches SW5 to SW10 are provided for each feeding mode to set the feeding mode, but the feeding mode setting operation is not limited to this embodiment. For example, the one-frame feed mode, the one-frame rewind mode, and the rewind mode are each provided with a dedicated operation switch, but the index mode, the frame designation mode, and the skip mode are replaced by one dedicated operation switch.
It is also possible to provide a number of mode switches and switch the index mode, the frame designation mode, and the skip mode in a predetermined order each time the mode switch is operated.

FIG. 12 shows a modified example of the feeding mode discrimination in which the index mode, the frame designation mode and the skip mode are switched by one mode switch. In step 301, it is determined whether or not the one-frame feed switch SW5 is operated. When the one-frame feed switch SW5 is operated, the process proceeds to step 302 to set the one-frame feed mode. In step 303, it is determined whether or not the one-frame return switch SW6 is operated, and the one-frame return switch SW is
When 6 is operated, the routine proceeds to step 304, where the one frame return mode is set. In step 321, it is determined whether or not the rewind switch SW10 is operated. If the rewind switch SW10 is operated, step 322 is performed.
Go to and set the rewind mode.

In step 323, it is determined whether or not a mode switch (not shown) for switching between the index mode, the frame designation mode and the skip mode is operated. If the mode switch is operated, the process proceeds to step 324. At step 324, the currently set feeding mode among the index mode, the frame designation mode and the skip mode is recognized. If the index mode is currently set in step 325, the flow advances to step 326 to switch the setting from the index mode to the frame designation mode. If the current frame designation mode is set in step 327, the flow advances to step 328 to switch the setting from the frame designation mode to the skip mode. When the current setting mode is neither the index mode nor the frame designation mode, it is determined that the skip mode is set and the process proceeds to step 329, and the setting is switched from the skip mode to the index mode. In step 330 where the setting of the feeding mode is completed, the set feeding mode is displayed on the video monitor 23. In the following step 331, it is determined whether or not the mode switch is operated, and when it is operated, the feeding mode switched by the mode switch is not the mode desired by the user, and the user is in the feeding mode. It is determined that the user wants to re-change the above, and the process returns to step 324, and the feeding mode is set again by the mode switch. If the mode switch is not operated, the process returns to step 126 in FIG.

In steps 126 to 137 after the return, the processing according to the feeding mode set in the feeding mode discrimination routine shown in FIG. 11 or 12 is performed. That is, when the single frame feed mode is set, step 1
26 to step 127, the one-frame feed mode processing shown in FIG. 13 is performed, and when the one-frame return mode is set, the routine proceeds from step 128 to step 129.
The one-frame returning process shown in 4 is performed. When the index mode is set, the process proceeds from step 130 to step 131 to perform the index mode processing shown in FIG. 15, and when the frame designation mode is set, the process proceeds from step 132 to step 133. The frame designation mode process shown in 16 is performed. Further, when the skip mode is set, the routine proceeds from step 134 to step 135 to perform the skip mode processing shown in FIG. 17, and when the rewind mode is set, the routine proceeds from step 136 to step 137. The rewinding process shown in 18 is performed. When all of the above feeding modes are not set, the process proceeds to step 104.

The one-frame feed mode process will be described with reference to the one-frame feed mode routine shown in FIG. As mentioned above,
Immediately after the film 3 is sent out from the cartridge 2, it is the first
The frame is set at the image pickup position. If one frame is fed in this state, the film 3 is started to be wound without displaying the image of the first frame, and the second frame is set to the image pickup position. Therefore, in this embodiment, when the one-frame feed operation is performed when the first frame is set to the image pickup position, the image of the first frame is first input and displayed. Further, if one frame is fed when the last frame is at the image pickup position, the film 3 is fed to a portion where there is no frame to be displayed, which causes confusion to the user. Therefore, in this embodiment, if the one-frame feed operation is performed when the last frame is at the image pickup position, the one-frame feed is prohibited and a warning is issued. Further, if the reproducing head MH1 is always kept in contact with the magnetic recording portion 3b of the film 3 when feeding one frame, the film 3 may be damaged. Therefore, in this embodiment, it is checked whether or not the magnetic data of the next frame has already been reproduced and stored in the memory 26 before the feeding of one frame, and if the data of the next frame is stored, the magnetic data at the time of feeding one frame is checked. The head MH1 is not pressed against the film 3 so that the magnetic data is not reproduced.

In step 401, it is determined whether or not the first frame of the film 3 is set at the image pickup position, and the first frame
If the frame is in the image pickup position, the process proceeds to step 401A, and it is confirmed whether or not the film 3 has been fed from the cartridge 2, that is, immediately after the initial feeding. Immediately after the initial feeding, the process proceeds to step 409, and if not, step 402.
Proceed to. Normally, the first frame is set to the image pickup position as described above when the film is fed out after the cartridge is loaded.
In this case, if the one frame is fed, the image of the first frame is not displayed. In that case, therefore, the one frame is not fed, and the image of the first frame is displayed first.

If the first frame is not in the image pickup position, it is determined in step 402 whether or not the last frame is set in the image pickup position. If the last frame is in the image pickup position, the process proceeds to step 403, otherwise. If so, go to step 404. Since some magnetic data is recorded in the frame that has been photographed, the frame having the maximum frame number in which the magnetic data is recorded may be the final frame. 1 even though the last frame is in the shooting position
When the frame feed switch SW5 is operated, one frame is not fed, and in step 403, "Because it is the last frame, no more,
A warning message "Cannot advance frames" is displayed on the video monitor 23 and a buzzer Bz is sounded to warn the user, and the process returns to step 104 of FIG.

As described above, in the one-frame feed mode of this embodiment, if the one-frame feed operation is performed when the last frame is set at the image pickup position, the one-frame feed is prohibited and a warning is given. Since it was done, there is no need to feed the film to the part where there is no frame to display,
Operability is improved. Even when the fast-forwarding frame feed mode is provided, similarly, when the fast-forwarding frame feed operation is performed when the last frame is at the image pickup position, the frame feed is prohibited and a warning is issued. When the first frame is set to the image pickup position and the one frame feed operation is performed, the image of the first frame is input and displayed, and when the first frame is not in the image pickup position, the one frame feed operation is performed. When the first frame is in the image pickup position, the image can be displayed from the first frame when the first frame is set in the image pickup position. In particular, even if the one-frame feeding mode is set after the film is fed from the cartridge, the images can be displayed in order from the first frame.

If the frame at the image pickup position is neither the first frame nor the last frame, one frame is fed. First in step 404,
It is determined whether or not the magnetic data of the next frame has already been reproduced and stored in the memory 26. If there is data of the next frame, it is not necessary to reproduce the magnetic data, so step 40
If you skip 5 and there is no data for the next piece, step 4
In step 05, the reproducing head MH1 is brought into contact with the film 3 and the reproducing operation of the magnetic data by the reproducing circuit 24 is started. In this way, when the magnetic data of the next frame is already reproduced and stored in the memory 26, the magnetic head MH
Since the information reproducing operation is not performed while the 1 is retracted from the film 3, the occurrence of scratches on the film 3 and the abrasion of the magnetic head MH1 are suppressed. Then step 406
Then, the winding of the film 3 is started by the winding driver DR3 and the motor M3, and it is determined in the next step 407 whether or not the next frame is set to the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2. To do. When the next frame is set to the image pickup position, the motor M3 is stopped and the film 3
Then, the reproduction head MH1 is retracted from the film 3 and the reproduction of magnetic data by the reproduction circuit 24 is completed. In step 409, CCD9
And the image of the photographing frame is inputted by the image pickup circuit 21. In step 410, frame information is generated from the information stored in the memory 26, in step 411, an image is displayed on the video monitor 23, and in step 412, the video monitor 2 is displayed.
The magnetic data of the current frame is displayed in 3. The magnetic data of the current frame includes the shooting conditions of the frame and shooting contents recorded by the photographer himself.

The one-frame return mode process will be described with reference to the one-frame return mode routine shown in FIG. If one frame is returned when the first frame is in the image pickup position, the film 3 is fed to a portion where there is no frame to be displayed, and the user is confused. Therefore, in this embodiment, if the one-frame returning operation is performed when the first frame is at the image pickup position, the one-frame returning is prohibited and a warning is issued. Also, when the index mode is set, the film 3 is fed to the last frame,
The last frame is set to the imaging position. If one frame is rewound in this state, the image of the last frame is not displayed and the next frame is rewound. Therefore, in this embodiment, when the last frame is at the image pickup position, it is confirmed whether or not the index mode is set, and when the index mode is set, one frame return is prohibited and the image of the last frame is input. And display it. If the index mode is not set, one frame is returned.

In step 501, it is determined whether or not the first frame of the film 3 is set at the image pickup position, and the first frame
If the frame is in the image pickup position, the process proceeds to step 502, and if not, the process proceeds to step 503. When the 1 frame return switch SW6 is operated even though the 1st frame is in the image pickup position, the 1 frame is not returned, and in step 502, a warning message "The frame cannot be returned because it is the 1st frame" is displayed. While displaying on the monitor 23, the buzzer Bz is sounded to give a warning, and the process returns to step 104 in FIG.
As described above, when the one frame returning operation is performed when the first frame is set to the image pickup position, the one frame returning is prohibited and the warning is issued. The operability is improved without being fed. Even when the fast-forwarding frame returning mode is provided, similarly, when the fast-forwarding frame returning operation is performed when the first frame is at the image pickup position, the frame returning is prohibited and a warning is issued.

If the first frame is not in the image pickup position, it is judged in step 503 whether or not the last frame is set in the image pickup position. If the last frame is in the image pickup position, the process proceeds to step 504, otherwise. If so, go to step 505. Since some magnetic data is recorded in the frame that has been photographed, the frame having the maximum frame number in which the magnetic data is recorded may be the final frame. If the last frame is at the image pickup position, it is determined in step 504 whether or not the index mode is currently set. If it is the index mode, the process proceeds to step 508, and if not, the process proceeds to step 505.
If one frame is returned when the film is fed in the index mode and the last frame is at the image pickup position, the image of the last frame is not displayed. In that case, the one frame is not returned and the image of the last frame is not displayed. Display. As described above, when the one frame return operation is performed when the last frame is set at the image pickup position, the image of the last frame is input and displayed, and when the last frame is not at the image pickup position, the one frame return operation is performed. Since the film is rewound by one frame, the image can be displayed from the last frame even if the one-frame return mode is set when the last frame is at the image pickup position. In particular, even if the one-frame feed mode is set after the film is fed in the index mode and the last frame is set at the image pickup position, images can be displayed in order from the last frame.

When the frame at the image pickup position is not the last frame and is not in the index mode, one frame is returned. In step 505, the rewinding of the film 3 is started by the sending / rewinding driver DR1 and the motor M1, and in the following step 506, the next frame is set to the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2. It is determined whether it has been done. When the next frame is set to the image pickup position, the motor M1 is stopped in step 507 to complete the one frame return of the film 3. In step 508, the CCD 9 and the image pickup circuit 21 input the image of the photographing frame. Memory 2 in step 509
The frame information is generated based on the information stored in 6, and in the following step 510, an image is displayed on the video monitor 23, and in step 511, the magnetic data of the current frame is displayed on the video monitor 23. The magnetic data of the current frame includes the shooting conditions of the frame and shooting contents recorded by the photographer himself.

The index mode processing will be described with reference to the index mode routine shown in FIG. As described above, the index mode is a mode for first fetching and displaying the information of all the frames and then selecting a frame for displaying an image while looking at the index information of all the displayed frames. Normally, the index mode is set when the first frame immediately after the film is fed from the cartridge is at the image pickup position, but in this embodiment, the index mode can be set regardless of which frame is at the image pickup position. If the index mode is set when the last frame is set to the image pickup position, the magnetic data of all the frames have already been reproduced and stored, so that they are displayed immediately. In addition,
Since some magnetic data is recorded in the photographed frame, the maximum frame in which the magnetic data is recorded may be the final frame. In step 600, it is confirmed whether or not the photographing frame information of the film 3 of the loaded cartridge 2 is stored in the memory 26. If the shooting frame information has already been recorded, the process proceeds to step 602, and if not, the process proceeds to step 601. This avoids wasteful film feeding. In step 601, it is determined whether or not the prescribed final frame of the film 3 is in the image capturing position. If the final frame is in the image capturing position, the process proceeds to step 602, and if not, the process proceeds to step 604. When the last frame is at the image pickup position, the magnetic data from the first frame to the last frame is reproduced and stored in the memory 26 during the film feeding process up to the last frame, so that it is stored in the memory 26 in step 602. Extract the data of all the pieces that are
In the following step 603, the data of all frames are displayed as an index on the video monitor 23. Then, the process returns to step 104 in FIG. 5 to wait for the next film feeding instruction from the user.

When the last frame is not at the image pickup position, the magnetic data from the first frame to the frame at the current image pickup position has already been reproduced and stored in the memory 26, but the magnetic data from the next frame to the last frame is recorded. Since it is considered that the data has not been reproduced yet, the magnetic data from the next frame to the last frame is reproduced and stored as the film is fed to the last frame. In step 604, the reproducing head MH1 is brought into contact with the film 3 to start reproduction of magnetic data by the reproducing circuit 24 and storage in the memory 26, and in the following step 605, the driver DR3
Then, the winding of the film 3 is started by the motor M3. In step 606, the photo interrupters PH1 and PH
On the basis of the perforation detection result detected by 2, it is judged whether or not the prescribed final frame of the film 3 has reached the image pickup position, and when the final frame has reached the image pickup position, step 60
Proceed to 7. Since some magnetic data is recorded in the frame that has been photographed, the frame having the maximum frame number in which the magnetic data is recorded may be the final frame. In step 607, the motor M3 is stopped to end the winding of the film 3, and the reproducing head MH1 is retracted from the film 3 to end the reproduction of magnetic data by the reproducing circuit 24. Next, in step 608, the magnetic data of all the frames stored in the memory 26 are extracted, and in the following step 609, the data of all the frames are index-displayed on the video monitor 23. Then, the process returns to step 104 in FIG. 5 to wait for the next film feeding instruction from the user.

As described above, in the index mode of this embodiment, the information of each photographing frame is reproduced while the film 3 is fed to the last frame, and the information of each reproduced photographing frame is displayed. It is possible to know what kind of image is being photographed on each photographing frame of the film 3 before displaying, and it is possible to feed the frame for which an image is to be displayed to the image pickup position and immediately display the image. Operability during film feeding is improved. Further, since the information of each photographing frame is reproduced while the film 3 is fed to the last frame and the information of each reproduced photographing frame is stored, the index information of all the photographing frames of the film 3 can be displayed at any time. Further, in the index mode, since the magnetic data has already been reproduced from the first frame to the frame at the image pickup position and stored in the memory 26, the reproducing head MH1 while feeding the film 3 from the next frame to the last frame. Were brought into contact with the film 3 to reproduce magnetic data and stored in the memory 26. This allows film 3
Of scratches and wear of the magnetic head MH1 are suppressed. Furthermore, if the final frame in which the magnetic data is recorded is taken as the final frame in the index mode, the film feeding and the magnetic data reproducing operation up to the unexposed final frame can be omitted. Incidentally, when the index mode is set in the state of being in the middle frame, it is possible to omit the frame information already stored in the memory 26 between that time and the last frame. Further, in this embodiment, the data of all the frames are reproduced, and they are stored in the memory 26 and displayed collectively. However, the data may be sequentially displayed in the process of reproduction. In that case, it is also possible to add a function of stopping the index mode on the way.

The designated frame mode processing will be described with reference to the designated frame mode routine shown in FIG. As described above, the designated frame mode is a mode for displaying an image of an arbitrary frame designated by the user. In this embodiment, a warning is given when a frame number larger than the maximum frame number of the film 3 is designated. If the designated frame number is larger than the frame number at the current imaging position, the magnetic data from the next frame to the designated frame is reproduced and stored as the film 3 is wound up. If the frame number is smaller than the frame number at the current imaging position, the reproduction and storage of the magnetic data up to the frame at the imaging position has already been completed when the frame was previously wound to the imaging position. Do not play or remember. Since some magnetic data has been recorded in the frames that have already been shot, by setting the maximum frame in the designated frame mode as the maximum frame that has already been shot, the film is fed and the magnetic data of the last frame not exposed is recorded. It is not necessary to perform the playback operation. In step 701, the designated frame number input from the input device 27 is input. Continued Step 70
In step 2, it is judged whether or not the designated frame number is larger than the specified maximum frame number of the film 3, and if it is larger, the process proceeds to step 703, and if not, the process proceeds to step 704. Note that, as described above, the maximum frame number may be the maximum frame number of a photographed piece in which magnetic data is recorded. When a frame number larger than the maximum frame number is specified, a warning message "The specified frame exceeds the maximum frame of the film" is displayed on the video monitor 23 and the buzzer Bz is sounded at step 703. Give a warning.

When a frame number smaller than the maximum frame number is designated, it is judged at step 704 whether or not the designated frame number is larger than the frame number at the current image pickup position, and it is decided that it is larger than the frame number at the image pickup position. If it is larger, the process proceeds to step 705, where the reproducing head MH1 is brought into contact with the film 3 to start reproducing the magnetic data by the reproducing circuit 24, and at the same time to start storing the reproduced magnetic data in the memory 26. On the other hand, when the designated frame number is smaller than the frame number at the image capturing position, the magnetic data up to the frame at the image capturing position has already been reproduced and stored in the memory 26. Therefore, step 705 is skipped and the magnetic data Do not play or remember. In step 706, when the designated frame number is larger than the frame number at the image pickup position, the film winding is started by the winding driver DR3 and the motor M3, and when the designated frame number is smaller than the frame number at the image pickup position. Rewinding driver DR
1 and the motor M1 start the rewinding of the film 3.

In step 707, it is determined whether or not the designated frame is set to the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2. When the designated frame is set to the image pickup position, the process proceeds to step 708. , The driving driver and motor are stopped to finish the film feeding, and the reproducing head MH
1 is withdrawn from the film 3 and the reproduction of the magnetic data by the reproduction circuit 24 is completed. Thus, in the frame designation mode, the magnetic data from the first frame to the frame at the image pickup position has already been reproduced and stored in the memory 26.
The number of the designated frame is larger than the number of the frame in the shooting position,
Only when the film 3 is wound up, the magnetic head MH1 is brought into contact with the film 3 to perform the information reproducing operation. As a result, scratches on the film 3 and the magnetic head M
The wear of H1 is suppressed. In step 709, CCD9
And the image of the designated frame is input by the image pickup circuit 21. In step 710, the video control circuit 22 generates frame information, in step 711, an image is displayed on the video monitor 23, and in step 712, the magnetic data of the current frame is displayed. The magnetic data of the current frame includes the shooting conditions of the frame and shooting contents recorded by the photographer himself.

As described above, in the frame designation mode of this embodiment, the photographing frame designated by the input device 27 is fed to the image pickup position to display the image, so that the contents of the image of each photographing frame are displayed. With the film that is known, you can immediately display the image of the frame you want to see. Further, when the number of shooting frames designated by the input device 27 exceeds the maximum number of frames, a warning is given, so that the user can immediately notice an erroneous operation and repeat the frame designating operation, thereby improving operability. You can

The skip mode processing will be described with reference to the skip mode routine shown in FIG. As described above, the skip mode is a mode in which images are displayed one frame at a time for a certain period of time. In this embodiment, since the skip mode is executed while the film is being wound, a warning is given when the skip mode is set when the last frame is at the image pickup position. If the skip mode is set when the first frame immediately after the film is fed from the cartridge 2 is in the image pickup position, the image of the first frame is first input and displayed. In step 801, it is determined whether or not the last frame is in the image pickup position. When the last frame is in the image pickup position, the process proceeds to step 802, and a warning message "The image cannot be displayed in the skip mode because it is the last frame" is displayed on the video monitor Is displayed and the buzzer Bz is sounded to give a warning, and the process returns to step 104 of FIG. 5 to wait for the next film feeding instruction from the user. At this time, the film may be rewound by fast-forwarding to the first frame, and the image may be displayed in the skip mode from the first frame. Further, since some magnetic data is recorded in the frame that has been photographed, the maximum frame in which the magnetic data is recorded may be the final frame.

If the last frame is not in the image pickup position, step 8
In 03, it is determined whether or not the first frame is at the image pickup position. Immediately after the film is fed from the cartridge 2, the first frame is set to the image pickup position, but the image of the first frame is not displayed. Therefore, when the first frame is in the image pickup position, the film 3 is not wound and the step is performed. After proceeding to step 809 and thereafter, first, the image of the first frame is input and displayed. If the first frame is not in the image pickup position, it is determined in step 804 whether or not the magnetic data of the next frame has already been reproduced and stored in the memory 26. If there is no magnetic data, the process proceeds to step 805 to reproduce. Playback circuit 24 by bringing head MH1 into contact with film 3
The magnetic data is started to be reproduced by the memory 2
The storage of the reproduction data in 6 is started. If the magnetic data is already stored in the memory 26, step 80
Skip 5 In step 806, the winding of the film 3 is started by the winding driver DR3 and the motor M3.

As described above, in the skip mode of this embodiment, when the skip mode is set when the first frame is set to the image pickup position, the image of the first frame is input and displayed, and the first frame is displayed. If the skip mode is set when the frame is not in the shooting position, the film is wound up one frame, so even if the skip mode is set when the first frame is in the shooting position, the image is displayed from the first frame. can do.
In particular, even if the skip mode is set after the film is fed from the cartridge, the images can be displayed sequentially from the first frame. Also, the magnetic data of the next frame is stored in the memory 2.
Since the magnetic head MH1 is brought into contact with the film 3 to perform the information reproducing operation only when it is not stored in the memory 6, the occurrence of scratches on the film 3 and the abrasion of the magnetic head MH1 are suppressed.

In step 807, the photo interrupter PH
1, based on the perforation detection result by PH2, it is determined whether or not the next frame is set to the image capturing position. When the next frame is set to the image capturing position, the process proceeds to step 808, and the driver DR3 and the motor M3 are stopped. Thus, the winding of the film 3 is stopped, the reproducing head MH1 is retracted from the film 3, and the reproduction of magnetic data by the reproducing circuit 24 is completed. In step 809, the image of the designated frame is input by the CCD 9 and the image pickup circuit 21. Step 810
Then, the video control circuit 22 generates frame information, and in the subsequent step 811, an image is displayed on the video monitor 23, and in step 812, the magnetic data of the current frame is displayed. The magnetic data of the current frame includes the shooting conditions of the frame and shooting contents recorded by the photographer himself. Step 8
In step 13, the display of the image is continued for a predetermined time, and in the following step 814, it is determined whether or not the frame on which the image is currently displayed is the last frame of the film 3, and if it is the last frame, the process returns to step 104 of FIG. If it is not the last piece, step 804
Return to and repeat the above process until the final frame. At this time, since some magnetic data is recorded in the photographed frame, the frame having the maximum frame number in which the magnetic data is recorded may be the last frame. The image display in the skip mode may be performed while rewinding the film 3 into the film cartridge 2. Further, it is possible to add a function of canceling the skip mode on the way.

The rewinding process will be described with reference to the rewinding mode routine shown in FIG. In step 901, it is determined whether or not a film image is displayed on the video monitor 23. When the film image is displayed, the process proceeds to step 902 to stop the display. Next, in step 903, the rewinding driver DR1 and the motor M1 start the rewinding of the film 3 into the cartridge 2, and the following step 904.
Then, it is determined whether or not the film 3 is rewound into the cartridge 2 based on the perforation detection result by the photo interrupters PH1 and PH2. When the rewinding is completed, the process proceeds to step 905, the motor M1 is stopped, and the rewinding of the film 3 is completed. Further, after the driver DR2 and the motor M2 close the cartridge door 2d in step 906, the film 3 is discharged from the cartridge chamber by the eject mechanism, and the process returns to step 104 in FIG.

-Modification of Embodiment- In the above-described embodiment, the film 3 is fed from the cartridge 2 so that the feeding mode of the film 3 can be selected after confirming the contents of the loaded film 3. Is initially fed until the first frame reaches the image pickup position, and information other than the image magnetically and optically recorded on the leader portion of the film 3 or the first frame is reproduced to set the image pickup position. An example is shown in which the contents of the film 3 can be confirmed by displaying information other than the reproduced leader portion and / or the image of the first frame without displaying the image of the first frame. However, it is sufficient that the information recorded in the reader unit is fed until the 0th frame reaches the image pickup position without being initially fed until the 1st frame reaches the image pickup position. Where 0th
The piece is a virtual piece adjacent to the leader side of the first piece.

Therefore, referring to FIG. 19, a modified example of the above-described embodiment in which the information recorded in the reader is read while the film is initially fed until the 0th frame reaches the image pickup position will be described. Since this modification is different only in part of the main processing shown in FIG. 6 of the above-described embodiment, differences from the above-described embodiment will be mainly described. After the feeding of the film 3 is started, the perforation detection is started in step 118, and the 0th frame of the film 3 is set to the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2 in step 119A. It is determined whether or not it has been set. When the 0th frame is set to the image pickup position, the process proceeds to step 120, the feeding of the film 3 is stopped, and the input of magnetic data and optical data is completed. After that, optical data processing and magnetic data processing are performed in the same manner as in the above-described embodiment, and the film 3
The information read from the reader unit of the above is displayed on the video monitor. In this way, the film is fed out from the cartridge, and the film is fed so that the portion on the leader side for one frame rather than the first frame faces the imaging position, and it is magnetically or optically recorded on the leader portion of the film. Since information other than images is played back and displayed, information about the contents of the film is displayed before selecting the feeding mode of the loaded film cartridge, and the optimum film feeding according to the contents of the film is displayed. You can select the mode.

-Other Modifications of Embodiment- By the way, when the film in which no information is recorded in the leader section is initially fed and the 0th frame is stopped at the image pickup position, it is recorded in the 1st frame. Since the stored information cannot be read, the contents of the loaded film cannot be confirmed at all. Therefore, referring to FIG. 20, it is confirmed whether or not the information is recorded in the leader portion during the initial feeding of the film, and when the information is recorded in the leader portion, the 0th frame is fed to the imaging position, Another modified example of the above-described embodiment will be described in which the first frame is fed to the image pickup position when no information is recorded in the reader unit. Since this modification is different only in part of the main processing shown in FIG. 6 of the above-described embodiment, differences from the above-described embodiment will be mainly described. After the feeding of the film 3 is started, the detection of perforation is started in step 118, and the subsequent step 119B
It is determined whether or not the information is recorded in the reader section. If the information of the reader section has been read by the reproducing magnetic head MH1 and the optical reading device 11, the procedure proceeds to step 119C, and if the information of the reader section has not been read, the procedure proceeds to step 119D. If the information is recorded in the reader section, it is determined in step 119C whether or not the 0th frame of the film 3 is set at the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2. When the 0th frame is set to the image pickup position, the process proceeds to step 120, the feeding of the film 3 is stopped, and the input of magnetic data and optical data is completed. After that, optical data processing and magnetic data processing are performed in the same manner as in the above-described embodiment, and the film 3
The information read from the reader unit of the above is displayed on the video monitor.

On the other hand, when the information is not recorded in the leader portion, it is determined in step 119D whether or not the first frame of the film 3 is set at the image pickup position based on the perforation detection result. When the first frame is set to the image pickup position, the process proceeds to step 120, the feeding of the film 3 is stopped, and the input of magnetic data and optical data is completed. At this time, the information recorded on the first frame can be read even if the information is not recorded on the leader section. After that, optical data processing and magnetic data processing are performed as in the above-described embodiment, and the information read from the reader section of the film 3 is displayed on the video monitor 23.
As described above, when information other than the image is not recorded on the leader portion of the film, the film is further fed so that the first frame faces the imaging position, and the first frame of the film is magnetically or optically supplied. Since the information other than the recorded image is reproduced and displayed, the information about the film contents is displayed before selecting the feeding mode of the loaded film cartridge, and it is suitable for the contents of the film. A variety of film feeding modes can be selected.

-Other Modifications of Embodiment- In the above-described embodiment, the film 3 is loaded from the cartridge 2 so that the feeding mode of the film 3 can be selected after confirming the contents of the loaded film 3. The initial feed until the first frame reaches the image pickup position, and the information other than the image magnetically and optically recorded on the leader section of the film 3 and the first frame is reproduced and set to the image pickup position. An example is shown in which the contents of the film 3 can be confirmed by displaying information other than the reproduced leader portion and / or the image of the first frame without displaying the image of the first frame. However, for a film in which information is not recorded in the leader section and each shooting frame but only the image is recorded, the content of the film is confirmed even when the film is initially fed until the first frame reaches the image pickup position. In addition to not being able to obtain information about the leader section and the first frame, the image of the first frame is not displayed.

Therefore, referring to FIG. 21, the information is reproduced while the film is initially fed until the first frame reaches the image pickup position, and when the information is not reproduced from the leader section and the first frame, the information is displayed. A modified example of the above embodiment in which the image of the first frame is displayed instead will be described. Note that this modified example is different only in part of the main processing shown in FIG. 7 of the above-described embodiment, and therefore the differences from the above-described embodiment will be mainly described. As described above, in steps 121 and 122, the optical data processing and the magnetic data processing are performed, and the optical data and the magnetic data obtained from the leader section and the first frame are processed with the initial feeding of the film. In the following step 122A, it is judged whether or not there is reproduction data, and if there is reproduction data for the leader section and / or the first frame, the process proceeds to step 123 and thereafter, and as described above, the leader section and / or the first frame is fed at the initial feeding of the film. Display information read from.

On the other hand, if there is no reproduction data for the leader section and the first frame, it is determined that the film has no information recorded thereon, and the process proceeds to step 122B. Then, in step 122B, the image of the first frame is input by the CCD 9 and the image pickup circuit 21, and in the following step 122C, the image of the first frame is displayed on the video monitor 23. In this way, while feeding the film from the cartridge, the information other than the image recorded on the leader portion and the first frame of the film is reproduced,
When information other than the image is not recorded on the reader section and the first frame, the first frame is fed to the image pickup position and the image of the first frame is displayed on the display means. If information other than images is recorded magnetically or optically in the reader,
The portion closer to the leader by one frame than the first frame, that is, the 0th frame is fed to the image pickup position to display information other than the image recorded in the leader section, and the information other than the image is recorded in the reader section. When the information other than the image is recorded on the first frame, the first frame is fed to the image pickup position and the information other than the image recorded on the first frame is displayed. This makes it possible to handle a film on which information other than images is recorded and a film on which information is not recorded, and in the former film, the contents of the film before the feeding mode of the loaded film cartridge is selected. Information is displayed, and the optimum film feeding mode can be selected according to the content of the film. Also, in the latter film, the image of the first frame is displayed before selecting the feeding mode of the loaded film cartridge, and the content of the film is confirmed by looking at the image of the first frame, and it is optimal according to the content of the film. A variety of film feeding modes can be selected.

-Other Modifications of Embodiment- In the above-described embodiment, an example is shown in which information is read from the information recording unit that records information other than the images of all the shooting frames in the index mode, and the information of all the shooting frames is displayed as an index. It was However, execution of the index mode is meaningless for a film on which no information is recorded.
Therefore, referring to FIG. 22, a modified example of the above embodiment will be described in which the recording information other than the image is reproduced during the initial feeding of the film and the setting of the index mode is prohibited when there is no recording information. It should be noted that this modification is different only in part of the index mode processing shown in FIG. 15 of the above-described embodiment, and therefore the differences from the above-described embodiment will be mainly described. When the main routine shown in FIGS. 5 to 7 is executed, the recording information other than the image is reproduced while the film 3 is sent out from the cartridge 2 and the initial feeding is performed until the first frame reaches the image pickup position. It is recorded in the memory 26. Then, the index mode switch SW7
When is operated to set the index mode, the microcomputer 20 executes the index mode routine shown in FIG.

In step 1101, it is determined whether or not information other than the image was recorded on the leader section and / or the first frame at the initial feeding of the film. If information is recorded in the leader section and / or the first frame,
When it is judged that the film has information other than the image recorded on each photographing frame, the steps 600 to 609 in FIG. 15 are executed to reproduce the information of each photographing frame and display the index. On the other hand, when the information other than the image is not recorded on the leader section and / or the first frame, it is determined that the film has no information recorded, and step 110
After proceeding to step 2 and prohibiting the setting of the index mode, a warning message "The index mode cannot be selected because the film has no information recorded" is displayed on the video monitor 23 in step 1103. In this way, the first frame of the film is fed to the imaging position while the first frame is being fed.
The magnetic recording information of the frame is reproduced, and when the magnetic recording information is not reproduced from the first frame, the setting of the index mode is prohibited. Therefore, the film in which no information is recorded is fed to the last frame in the index mode. It is possible to prevent useless operations that are performed. Further, when the magnetic recording information is not reproduced from the first frame, the setting of the index mode is prohibited and the warning is displayed.
It can be recognized that a film having no information recorded therein has been loaded.

-Other Modifications of the Embodiment-As described above, in the index mode, information other than the images recorded on all frames is fetched and displayed, and the images are displayed while viewing the index information of all the displayed frames. This is a mode for selecting a piece to watch. In the above-described embodiment, when the index mode is set, the information other than the image is reproduced and the last frame is fed to capture the information. However, it is not always the case that the last frame has been photographed. Some films were taken out of the camera and developed during shooting. In such a half-taken film, since the image and information other than the image are not recorded up to the last frame, it is meaningless to feed such a film to the last frame in the index mode. Therefore, according to FIG. 23, the frame having the largest frame number in which information other than the image is recorded is set as the final frame, the film is fed to the final frame, and the information of all photographed frames is taken in. An example will be described. It should be noted that this modification is different only in part of the index mode processing shown in FIG. 15 of the above-described embodiment, and therefore the differences from the above-described embodiment will be mainly described. In step 1101, it is determined whether or not information other than the image was recorded on the leader section and / or the first frame at the initial feeding of the film. If information other than the image is not recorded on the leader section and / or the first frame, it is determined that the film has no information recorded, and the process proceeds to step 1102 to prohibit the setting of the index mode, and then the step. At 1103, a warning message "The index mode cannot be selected because the film has no information recorded" is displayed on the video monitor 23. After that, the steps 607 to 609 of FIG. 15 described above are executed to display the information of all the frames as an index.

On the other hand, when information is recorded on the leader section and / or the first frame, it is judged that the film has information other than the image recorded on each photographing frame, and the above-mentioned FIG.
5. Steps 600 to 605 of No. 5 are executed to start reproduction of information and film winding. In step 1104, the presence / absence of recording information is confirmed. If there is recording information other than an image, it is determined that the frame is a photographed frame, and the process proceeds to step 606. If there is no recording information, it is determined that the frame is an unexposed frame, and step 110
Go to 5. In the case of the photographed frame having the record information, it is determined in step 606 whether or not the film is the final frame according to the regulation,
If it is the last frame, steps 607 to 60 of FIG. 15 described above.
9 is executed to display the information of all the frames as an index, and if it is not the last frame, the process returns to step 1104. On the other hand, in the case of an unexposed frame having no recording information, in step 1105, the frames up to the frame immediately before the frame in which the recording information is not detected are the frames already recorded with the recording information. Set as a piece. The frame set as the last frame in this index mode is effective in all subsequent film feeding, and the film is fed in the range from the first frame to the set last frame which has been photographed. After setting the last frame, the above steps 607 to 609 of FIG. 15 are executed to display the information of all photographed frames as an index.
In this way, the magnetic recording information of each shooting frame is reproduced while the film is being fed, and the frame with the highest frame number in which the magnetic recording information is reproduced is set as the final frame of the film. Useless operations such as feeding to a position are prevented. Further, since the film is fed within the range from the first frame to the frame having the maximum frame number in which the magnetic information set as the last frame is reproduced, in all film feeding modes including the index mode. Useless operations such as feeding the unexposed frame to the imaging position are prevented.

In the structure of the above embodiment and its modification, the taking lens 8, the CCD 9, the image pickup circuit 21 and the image control circuit 22 serve as an image reproducing means, the reproducing circuit 24, the reproducing magnetic head MH1 and the optical reading device 11. Represents information reproducing means, the video monitor 23 constitutes display means, the drivers DR1 and DR3 and the motors M1 and M3 constitute feeding means, and the microcomputer 20 constitutes control means.
