5 to 19 are flowcharts showing the processing of the microcomputer 20. The operation of the embodiment will be described with reference to these flowcharts. 5 to 7 are flowcharts showing the main program. When the power switch SW2 is turned on in step 101, the processing is started, and in step 102, each part initialization routine is executed to initialize each part.

<< Initial Setting of 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, the switch SW
It is determined from 3 whether the cartridge 2 is loaded in the cartridge chamber of the film image display apparatus 1 and 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, information of the loaded cartridge 2 is extracted from the memory 26 in step 203. 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, it is reconfirmed whether or not the power switch SW2 is turned on. If it is turned on, the process proceeds to step 105, and if not turned on, the process ends. In step 105, the eject switch SW1
If the eject switch SW11 is operated, the process proceeds to step 106, and if not, the process proceeds to step 105A. Eject switch SW
When 11 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, the eject switch SW11 is not operated, and the cartridge 2
In the state in which is not loaded, the state of waiting for the operation of the eject switch SW11 is continued while displaying the message prompting the loading of the cartridge 2.
On the other hand, when the cartridge 2 is 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 process proceeds to step 106D. When the eject switch SW11 is operated while the cartridge 2 is loaded, it is confirmed in step 106A whether or not the film 3 of the loaded cartridge 2 is rewound. When the film 3 has not been rewound into the cartridge 2, the film DR is rewound into the cartridge 2 by the driver DR1 and the motor M1 in step 106B. Step 1
At 06C, 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, the switch SW4
Check to see if the cartridge chamber lid 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. If the lid of the cartridge chamber is closed, the process proceeds to step 108, and if not, the process 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,
When 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 selected in step 109.
It is confirmed whether or not it has been developed by. If it is developed in the subsequent step 110, the process proceeds to step 113, and if it is not developed, the process proceeds 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, in step 113 the driver DR
2 to control the motor M2 to drive the cartridge door 2
Open d. In subsequent step 114, film data such as ISO sensitivity and the number of films recorded on the surface of the cartridge 2 is read by a reading device (not shown) and stored in the memory 26.

In step 115, the driver DR
1 is controlled to drive the motor M1 to feed the film 3 out of the cartridge 2. In step 116, reading of the optical data recorded on the film 3 is started by the optical reading device 11, and in the following step 117, the reproducing head MH.
1 is brought into contact with the film 3 and the reproducing circuit 24 starts reproducing magnetic data. Normally, the leader portion of the film 3 has information such as the cartridge loading direction of the camera recorded in an optical or magnetic recording form.
The reading of these data is started at the start of sending the data. The magnetic recording portion 3 of the first frame of the film 3
The magnetic data recorded in b 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, the photo interrupter P
Based on the perforation detection result detected by H1 and PH2, 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, and the first frame is set at the image pickup position. If so, the process proceeds to step 120 to control the driver DR1 to control the motor M.
1 is stopped 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. << Optical Data Processing >> In step 210 of FIG. 9, it is determined whether or not the camera loading direction information 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, the standard camera is 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. 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 the film on which such loading direction information is recorded is imaged as it is, an upside-down image is reproduced on the video monitor 23, so that the upside-down processing is performed in step 211. This upside-down reversal processing is performed by, for example, setting the CCD 9 to 180
The image may be turned upside down to be mechanically turned upside down, or the image pickup lens 8 may be used to turn the image upside down. Alternatively, the image may be digitally processed and vertically inverted. Next, in step 212, film information such as loading direction information 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. << Magnetic Data Processing >> In step 220 of FIG. 10, it is determined whether or not magnetic data is recorded in the leader portion of the film 3, and if magnetic data is recorded, step 221 is executed.
Proceed to step 2 if magnetic data is not recorded
Proceed to 25. 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 the subsequent step 224, the magnetic data of the leader portion extracted is stored in the memory 26.
To memorize. 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, the process proceeds to step 123 in FIG. 7 to generate the data to be displayed based on the data read at the time of feeding the film, and the display data generated in the following step 124 is video-generated. It is displayed on the 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.

In step 125, the CCD 9 and the image pickup circuit 21 are controlled to pick up the first frame at a low resolution to capture a rough image, and A / D conversion is performed via the A / D converter 102. Store in 101. In step 126, the driver DR3 is controlled to control the motor M.
3 is started to start winding the film 3. In step 127, it is confirmed whether or not the next shooting frame is set to the image pickup position facing the aperture 5. If the next frame is set to the image pickup position, the process proceeds to step 128 and the driver DR
3 and the winding of the film 3 by the motor M3 are stopped. Then, in step 129, the rough image of the frame set at the image pickup position is fetched similarly to the first frame and stored in the frame memory 101. In step 130, it is confirmed whether or not the frame currently at the image pickup position is the final frame. If it is not the final frame, the process returns to step 126 to capture and store the rough image of the next frame. On the other hand, when the acquisition and storage of the rough image of the final frame are completed, the driver DR1
Is controlled to drive the motor M1 to start the rewinding of the film 3. Then, in step 132, it is confirmed whether or not the first frame is fed to the image pickup position facing the aperture 5, and when the first frame is set to the image pickup position, step 1

In step 313, the set feeding mode is displayed on the video monitor 23, and the process returns to step 274 in FIG. 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 provided with dedicated operation switches, but the index mode, the frame designation mode, and the skip mode are provided with one mode switch instead of the dedicated operation switches. Each time the mode switch is operated, index mode, frame designation mode,
The skip mode may be switched in a predetermined order.

In steps 274 to 283 after the return, the processing according to the feeding mode set in the feeding mode discrimination routine shown in FIG. 14 is performed. That is, when the one-frame feed mode is set, the process proceeds from step 274 to step 275 to perform the one-frame feed mode process shown in FIG. 15, and when the one-frame return mode is set, the steps from step 276 to step 276. Proceeding to 277, the one-frame returning process shown in FIG. 16 is performed. If the frame designation mode is set, the process proceeds from step 278 to step 279 to perform the frame designation mode process shown in FIG. Further, when the skip mode is set, the process proceeds from step 280 to step 281 to perform the skip mode process shown in FIG. 18, and when the rewind mode is set, the process proceeds from step 282 to step 283. The rewinding process shown in 19 is performed. When all of the above feeding modes are not set, the process proceeds to step 284.

In step 284, it is confirmed whether or not the eject operation is performed by the switch SW11. When the eject operation is performed, the process proceeds to step 285, the film 3 is rewound into the cartridge 2 and the cartridge door 2d is closed, and then the cartridge door 2d is closed. The chamber lid is opened and the cartridge 2 is discharged. Then, the process returns to step 104 in FIG. In step 286, it is confirmed whether or not the index image display operation is performed by the key switch SW21. When the index image display operation is performed, the process proceeds to step 287, and the subroutine shown in FIG. 11 is executed to execute the index image display mode described above. Perform processing. Further, in step 288, it is confirmed whether or not the stored image display mode operation is performed by the key switch SW23,
When the stored image display mode operation is performed, step 289
Then, it is confirmed whether or not the detailed image of each frame is stored in the frame memory 101. If the detailed image is stored, the routine proceeds to step 290, where the subroutine shown in FIG. 12 is executed to perform the above-mentioned stored image display mode processing.

In step 291, it is confirmed whether or not the memory key switch SW24 is operated, and if it is operated, the process proceeds to step 292, and if not, step 273.

The detailed image of the frame at the image pickup position is fetched by the CCD 9 and the image pickup circuit 21 and stored in the frame memory 101 via the A / D converter 102. In step 293,
It is confirmed whether or not the variable N has reached the maximum number of frames Nmax, and when it has reached the maximum number of frames Nmax, the process returns to step 272. If not, the process proceeds to step 294, the variable N is incremented and the process returns to step 273.

The one frame feed mode process will be described with reference to the one frame feed mode routine shown in FIG. << 1 Frame Feed Mode Process >> As described above, the first frame is set to the image pickup position immediately after the film 3 is fed from the cartridge 2. If one frame is fed in this state, the film 3 starts to be wound without displaying the image of the first frame, and
The frame is set at 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. Furthermore, the playback head MH when feeding one frame
If the magnetic recording portion 3b of the film 3 is kept in contact with the film 1, 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. 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 judged 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 judged 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 stating that the frame cannot be fed is displayed on the video monitor 23 and the buzzer Bz is sounded to warn the user, and the process returns to step 273 in 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. As a result, the film is not fed to the portion where there is no frame to be displayed, and the 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.

When 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.

One frame return mode processing will be described with reference to the one frame return mode routine shown in FIG. << One-frame return mode processing >> If one frame is returned when the first frame is at the image pickup position, the film 3 will be 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. When the index mode is set, the film 3 is fed to the final frame, and the final frame is set to the image pickup 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 judged 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 273 of 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. Is not sent,
Operability is improved. 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 determined 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 designated frame mode processing will be described with reference to the designated frame mode routine shown in FIG. << Frame Designating Mode Processing >> 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. In the following step 702, it is determined 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 determined in step 704 whether or not the designated frame number is larger than the frame number at the current image capturing position, and the frame number at the image capturing position is larger than the frame number at the image capturing 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 at the image pickup position based on the perforation detection result detected by the photo interrupters PH1 and PH2. When the designated frame is set at 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. Also,
Since a warning is given when the number of shooting frames designated by the input device 27 exceeds the maximum number of frames, the user can immediately notice an erroneous operation and repeat the frame designating operation, thereby improving the operability. .

The skip mode processing will be described with reference to the skip mode routine shown in FIG. << Skip Mode Processing >> As described above, the skip mode is a mode in which images are sequentially displayed for each frame 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 final frame is at the image pickup position. In addition, the first after the film is sent out from the cartridge 2
If the skip mode is set when the frame 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 23.
Is displayed, the buzzer Bz is sounded to give a warning, and the process returns to step 273 in FIG. 13 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 at 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. In addition, the magnetic data of the next frame is stored in the memory 26.
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, 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
At 13, the display of the image is continued for a predetermined time, and at the following step 814, it is determined whether or not the frame on which the image is currently displayed is the final frame of the film 3, and if it is the final frame, the process returns to step 273 of FIG. If it is not the last piece, step 80
Returning to step 4, the above process is repeated 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. << Rewind Mode Processing >> 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 rewinding the film 3 into the cartridge 2, and in the following step 904, the film 3 is transferred to the cartridge 2 based on the perforation detection result by the photo interrupters PH1 and PH2. It is determined whether or not it has been rewound. 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 273 in FIG.
