Next, a specific operation sequence of the control circuit 41 will be described with reference to the flowchart starting from FIG.

When the power switch (not shown) is turned on and the control circuit 41 becomes operable, step (101) in FIG.
Start operation.

First, in step (101), the control circuit 41 initializes its own memory and ports. Then, in the next step (102), whether or not the film cartridge 21 is loaded is detected based on the signal of the cartridge presence / absence detection switch 28. When the film cartridge 21 is loaded, the process proceeds to step (103).
Here, it waits until the knob 8 is turned to close the film chamber (not shown). When the film chamber is closed, the process proceeds to step (104).

In step (104), the output signal of the battery voltage detection circuit 44 is A / D converted to check whether the battery voltage is sufficient for the operation of the camera. If it is determined that it is insufficient, step (105)
Then, a warning display notifying that the battery is defective is output to the display 3 and the subsequent operation is stopped. When the user sees this warning and replaces the battery, the operation starts again from step (101).

If it is determined that the battery voltage is sufficient, the process proceeds from step (104) to step (106) to output a control signal to the second motor drive circuit 47 so as to drive the second motor 37. I do. Then, in the next step (107), it is detected whether or not the light-shielding lid is opened based on the signal of the light-shielding lid open / close detection switch 39, and if it is detected that the light-shielding lid is opened, the process proceeds to step (108). In step (108), a control signal is output to the second motor drive circuit 47 so as to stop the second motor 37. In the following step (109),
A control signal is output to the first motor drive circuit 46 so as to drive the first motor 24 in the reverse direction. Thus, the rotation of the information display panel 33 is started. Further, since the film 22 is driven in reverse, the film 22 is not sent out from the film cartridge 21.

In the next step (110), an output signal (referred to as DD information in the flow) of the film information reading circuit 34 is read, and by decoding this signal, information such as film type, sensitivity or the number of shots, and the like are obtained. Information on the shooting state of the film can be obtained. In the next step (111), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. Then, in step (112), it is checked whether or not the obtained information of the shooting state of the film has been fully exposed. If all exposures have been completed, step (11)
Proceeding to 3), a control signal is output to the second motor drive circuit 47 so as to drive the second motor 37. Then, in the next step (114), it is detected whether or not the light-shielding lid is closed based on the signal of the light-shielding lid open / close detection switch 39, and if it is detected that the light-shielding lid is closed, the step (11) is performed.
Proceeding to 5), a control signal is output to the second motor drive circuit 47 so as to stop the second motor 37. In the following step (116), it is possible that the process may proceed to this step with the image displayed on the monitor 9. In such a case, a signal is output to the image processing circuit 52 to stop the display of the image and the monitor 9 and the power of the image sensor 51 are turned off. If no image has been displayed on the monitor 9 at the time of proceeding to this step, this step has no particular meaning. Then, it waits until the film cartridge is replaced.

If the information on the photographing state of the film 22 obtained in step (112) is not fully exposed, the flow advances to step (117). Is determined. If not exposed, the process proceeds to step (121) in FIG. 8, and normal film loading is performed. That is, step (12)
In 1), a control signal is output to the first motor drive circuit 46 so that the first motor 24 is driven to rotate forward. Thus, the feeding of the film 22 from the film cartridge 21 is started. Then, in the next step (122), it waits until the first frame of the film is set at a predetermined photographing position in accordance with the signal from the perforation detector 27. Then, in the next step (123), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24.

In step (124), the display 3
Update the display value of the film counter displayed in. Since a new film has just been loaded, "1" is displayed. In the next step (125), it is checked whether the switch SW1 which is turned on in the first stroke of the shutter button 2 is turned on. If it has not been turned on yet, the process proceeds to step (126), where it is checked whether the rewind switch 13 has been turned on.
If it is not turned on, the process returns to step (125), and the same operation is repeated thereafter.

In the step (125),
When it is detected that the switch SW1 is turned on, the process proceeds to step (127) to check whether the selection switch 10 for selecting use of the monitor 9 is turned on. If it is on, it is determined that the monitor 9 is to be used, and the process proceeds to step (128).
To an active state, and the electronic image picked up by the image pickup element 51 is displayed on the monitor 9 as a visible image in real time. Thereafter, the process proceeds to step (130).
If the selection switch 10 has not been turned on in step (127), the process proceeds to step (129) in which the monitor 9 is not used, the image processing circuit 52 is stopped, and the image sensor 51 and the monitor 9 are also turned off. Stop. Power supply may be stopped so that power consumption is minimized.
Thereafter, the process proceeds to step (130).

In step (130), information is input from the distance measuring sensor 43 to obtain information on the distance to the subject. Further, a lens driving amount necessary for bringing the taking lens 1 into a focused state is calculated according to the obtained information on the distance to the subject. In the next step (131), a signal is output to the third motor drive circuit 48 so as to drive the focus adjusting lens according to the calculated lens drive amount, and the third motor 49 is driven. In the following step (132), information is input from the photometric sensor 42 to obtain luminance information of the subject. Then, step (13)
In 3), the exposure such as the shutter speed and the aperture value is determined according to the obtained luminance information of the subject and the sensitivity information of the film 22 obtained in step (110).
At this time, it is also determined whether or not shooting should be performed using the flash device 56.

In the next step (134), the switch SW2 which is turned on by the second stroke of the shutter button 2
It is checked whether or not is turned on. If it is not turned on, the process returns to step (125), and the above-described flowchart is repeated. If it is turned on, the process goes to step (141) in FIG.

In step (141), the shutter 4 is turned on in accordance with the exposure determined in step (133).
5 is controlled. If it is determined that the flash device 56 is to be used, a control signal is output so that the flash device 56 emits light. Thus, exposure of the film 22 is performed. Regardless of whether the monitor 9 is used or not, a control signal is output to the image processing circuit 52 so that the image sensor 51 captures an image in synchronization with the exposure of the film 22.

In the next step (142), it is checked whether the selection switch 10 for selecting use of the monitor 9 is on. If it is on, it is determined that the monitor 9 is used, and the process proceeds to step (143), where a control signal is output to the image processing circuit 52 to switch the electronic image displayed on the monitor 9 in real time to a still image. This still image is an electronic image captured at a timing that can be regarded as substantially the same as the timing at which the exposure of the film 22 was performed in step (141).
This is an image almost coincident with the latent image exposed on the film.
Then, in step (144), the image data currently displayed as a still image is transferred to the external memory 53 and stored as image data of the film. In the case where photographing is continued using the same film, this data is overwritten and stored every time exposure is performed and this step or a step (149) described later is performed. That is, for the same film (one film), one frame of image data of the last shot is always stored.

In step (145), the process waits for the photographer to input the position of the main subject. If the photographed image is as in the example of FIG. 6B, the photographer looks at the electronic image displayed on the monitor 9 while viewing the electronic image shown in FIG.
Point to position 2. There are various methods for realizing the instruction. The cursor displayed on the monitor 9 may be moved using the cross switch 12, or a touch panel-like key may be arranged on the surface of the monitor 9. There is also a method of directly pointing the position of the main subject with a finger. In the next step (146), the process waits for the decision switch 11 indicating that the indication of the position of the main subject has been decided to be turned on, and when it is turned on, the process proceeds to step (147).

In step (147), various kinds of photographing data of the photographing frame including the data of the position of the main subject are transferred to and stored in the external memory 53 as photographing information data of the film. In the case where photographing is continued using the same film, this data is overwritten and stored every time exposure is performed and this step or a step (150) described later is passed. That is, for the same film, the photographing information data of one frame which is finally photographed is always stored. In the next step (148), the image processing circuit 5 performs the real-time display of the image on the monitor 9 which has been in the still image state in the step (143).
2 to output a control signal. Thereafter, step (151)
Proceed to.

If the selection switch 10 is turned off in step (142), the monitor 9 is determined not to be used, and the process proceeds to step (149). Here, the electronic image data captured in step (141) is deleted. The image data of the film is transferred to the external memory 53 and stored. The storage procedure is the same as that described in step (144). In the next step (150), various pieces of photographic data of the photographic frame are transferred to and stored in the external memory 53 as photographic information data of the film. The storage procedure is the same as that described in step (147).

However, since the monitor 9 is not used, the captured image cannot be viewed on the monitor, and inputting the information on the position of the main subject may cause an erroneous input. Ban. Therefore, for the information on the position of the main subject, for example, default data representing the center 13 of the screen is stored, or only when the monitor is not used, the information on the position of the main subject is not stored. do not do. Thereafter, the process proceeds to step (151).

In step (151), the first motor drive circuit 4 is driven to rotate the first motor 24 forward.
6 to output a control signal. This starts the winding of the film. In the next step (152), a signal is output to the magnetic signal interface circuit 50, and a recording current is applied to the magnetic head 31 so that information is recorded on the magnetic track 30 on the film 22 according to the stored photographing information data. Let it flow. Then, in step (153), the recording of the photographing information is completed, and it waits until the next photographing frame of the film is set at a predetermined photographing position in accordance with the signal of the perforation detector 27. In the following step (154), the first motor 2
The control signal is output to the first motor drive circuit 46 so as to stop the control signal No. 4.

In step (155), it is checked whether or not the shooting of the last frame of the film 22 has been completed. If the shooting of the last frame has not been completed yet, the process returns to step (124) and the above-mentioned flowchart is repeated. When the photographing of the last frame is completed, the process proceeds to step (156), where a control signal is output to the first motor drive circuit 46 so as to drive the first motor 24 in the reverse direction. Thus, the rewinding of the film 22 is started. In the next step (157), it waits until the film 22 is completely rewound to the film cartridge 21 in accordance with the signal of the perforation detector 27 and the like. In the following step (158), while reading the output signal of the film information reading circuit 34, it waits for the information display panel 33 to reach a predetermined stop position indicating that all exposures have been completed.

In the next step (159), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. In the following step (160), the film 22 is exposed Then, the image data and the photographing information data corresponding to the film 22 stored in the external memory 53 are deleted.
Then, the process proceeds to step (113) and subsequent steps.
Wait for the film 22 to be removed.

If it is determined in step (117) of FIG. 7 that the information of the filming state of the film is not unexposed, it is determined that the exposure is partial exposure, and step (161) in FIG.
Then, the control signal is output to the first motor drive circuit 46 so that the first motor 24 is driven forward. Thus, the feeding of the film 22 is started. Then, in the next step (162), signal input from the magnetic signal interface circuit 50 is started in order to obtain photographing information recorded on the magnetic track 30 on the film 22. In the following step (163), the frame on which the photographic information is recorded on the magnetic track 30 has been photographed, and the unrecorded frame has been determined as an unexposed frame, and the film 2
While sending 2, it is checked whether each frame is an unexposed frame. If the checked frame is not an unexposed frame, the flow advances to step (164), where it is checked whether the checked frame is the last frame of the film. Otherwise, return to step (163).

In step (163), it is checked whether the next frame is an unexposed frame. When an unexposed frame is detected, the process proceeds from step (163) to step (165), and waits until the detected unexposed frame is set at a predetermined exposure position in accordance with a signal from the perforation detector 27. Then, the next step (166)
, A control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. In the following step (167), the photographing information of the last exposed frame which is one frame before the detected unexposed frame is decoded, and the decoded information is stored in the external memory 53 for photographing the film which has been rewound in the past in the past. Check with information data. The storage of the shooting information data of the film to be rewound halfway will be described later.

In the next step (168), if there is matched data as the collation result, step (16)
Proceeding to 9), it is checked whether the selection switch 10 for selecting the use of the monitor 9 is on. If it is on, it is determined that the monitor 9 is used, and the process proceeds to step (170). Then, in this step (17)
At 0), the image data also stored in the external memory 53 is transferred to the image processing circuit 52 in association with the stored shooting information data of the film that has been rewound halfway. Then, in the next step (171),
A control signal is output to the image processing circuit 52 to display the transferred image data on the monitor 9. This allows the user to know what the last image of the currently loaded film was. When this step ends, the process returns to the step (124) in FIG.

If there is no matching data in the step (168), and if the use of the monitor 9 is not selected in the step (169), the process proceeds to the step (172), and Since the image is not displayed or cannot be displayed, a control signal is output to the image processing circuit 52 so that the image is not displayed on the monitor 9. When this step ends, the process returns to the step (124) in FIG.

If the last frame of the film is detected in step (164), the flow advances to step (173) to output a control signal to the first motor drive circuit 46 so as to drive the first motor 24 in the reverse direction. I do. Thus, the rewinding of the film 22 is started. Then, the next step (174)
Waits for the film 22 to be completely rewound into the film cartridge 21 according to the signal of the perforation detector 27 and the like. In the following step (175), while reading the output signal of the film information reading circuit 34, it waits for the information display panel 33 to reach a predetermined stop position indicating that all the exposures have been completed. Then, in step (176), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. Thereafter, the process proceeds to step (113) and subsequent steps to wait for the film to be taken out.

If it is detected in step (126) of FIG. 8 that the rewind switch 13 is on,
Proceeding to step (181) in FIG. 11, it is checked whether there is still enough free space in the external memory 53 to store the image data of the halfway rewind film and the photographing information data. If there is not enough free space, the process proceeds to step (182), and among the shooting information data of the halfway rewind film stored in the external memory 53, the shooting year, month, and
The oldest shooting information data than the date / hour / minute information is searched. Then, in step (183), the image data corresponding to the oldest photographing information data retrieved is deleted from the external memory 53. In the following step (184), the oldest photographing information data retrieved is deleted from the external memory 53.

If it is determined in step (181) that there is still enough free space in the external memory 53 to store the image data of the halfway rewind film and the photographing information data, the process proceeds from step (182) to step (182). (184)
Go to step (185) without going through step (185).
In this step (185), the image data corresponding to the film 22 stored in the step (144) or (149) is rewound halfway, and is additionally stored in the external memory 53 as the image data of the film 22. I do. Then, in the next step (186), the photographic information data corresponding to the film 22 stored in the step (147) or (150) is rewound halfway, and the external memory 53 is used as the photographic information data of the film 22. Is additionally stored.

Here, using the memory map of FIG.
A method of storing the image data of the film and the photographing information data in the external memory 53 will be summarized and described.

It is assumed that the external memory 53 has a storage capacity of eleven pieces including the image data of the film 22 and the photographing information data. Generally, an address is assigned to the memory in units of 1 byte, and storing image data in the memory requires at least several kilobytes or more, depending on the size and compression ratio of the image. Approximately several bytes to several tens of bytes are required to store the data. Here, for the sake of simplicity, both the image data and the photographing information data are modeled so as to be represented by one byte and are mapped into a memory.

The image data is stored in the area indicated by the even address starting with A in the memory, and the image data is stored in the area indicated by the odd address starting with A + 1. The photographing information data stored in the area indicated by the address A is the photographing information data of the currently loaded film, and is stored in step (147) or (150) in FIG. The image data stored in the area indicated by the address A + 1 is the image data of the currently loaded film, and has been stored in step (144) or (149) in FIG.

When the film is rewound for the first time, the photographing information data stored in the area indicated by the address A is moved to the address A + 2 in step (186) of FIG. The image data stored in the area indicated by A + 1 is stored in step (18).
In 5), the data is moved to the address A + 3 and stored.

In this state, when the second film is rewound halfway, the photographic information data stored in the area indicated by the address A is used in step (186) because the addresses A + 2 and A + 3 have already been used. The image data moved to the address A + 4 and stored is stored in the area indicated by the address A + 1.
In step 5), the data is moved to the address A + 5 and then stored.
Can store shooting information data and image data corresponding to.

If rewinding is performed halfway while 10 data are stored, the oldest data is erased according to the procedure described in steps (181) to (184). When the film that has been rewound halfway is loaded again and the shooting up to the last frame is completed, step (1) in FIG.
At 60), the data of the film is erased.

Returning to FIG. 11, in step (187), a control signal is output to the first motor drive circuit 46 so as to drive the first motor 24 in the reverse direction. Thus, the rewinding of the film 22 is started. Next step (18
In step 8), the control waits until the film 22 is completely rewound into the film cartridge 21 in accordance with the signal of the perforation detector 27 and the like. Then, the next step (1
In step 89), while reading the output signal of the film information reading circuit 34, the process waits until the information display panel 33 reaches a predetermined stop position indicating that partial exposure has been completed. In the following step (190), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24.
Thereafter, the process proceeds to step (113) and the subsequent steps.
Wait for to be taken out.

As described above, for the partially exposed film that has been partially photographed, the image data and photographing information data of the last photographed frame are stored in the camera as long as the capacity of the external memory 53 permits. 11 steps (18
1) to (186)).

When the rewinded film is loaded into the camera again, as described with reference to the flowchart of FIG. 10, the photographing information data recorded on the film is compared with the photographing information data stored in the camera. This is performed (step (167)), and if they match, it is possible to display the image data of the last photographed frame stored in the camera on the monitor 9 (step (171)).

The description of the first embodiment of the present invention has been completed.

(Second Embodiment) In the first embodiment, the use / non-use of the monitor is selected by the operation switch. However, the selection can be made by the remaining capacity of the battery.

In the second embodiment of the present invention, the use / non-use of the monitor is selected based on the remaining capacity of the battery. FIGS. 1 to 6A and 6B
The configuration and the like up to this point are the same as in the first embodiment.

7 and 11 execute the same flowchart among the flowcharts executed by the control circuit 41. The flowchart of FIG. 12 replaces FIG. 8, the flowchart of FIG. 13 replaces FIG. 9, and the flowchart of FIG. FIG. 14 instead
Are respectively executed. Therefore, here, FIG. 12 which is a changed part from the first embodiment is described.
14 will be described.

If the information of the shooting state of the film loaded in step (117) in FIG. 7 is not exposed, the process proceeds to step (221) in FIG.

In step (221), the first motor drive circuit 4 is driven to rotate the first motor 24 forward.
6 to output a control signal. Thus, the feeding of the film 22 is started. In the next step (222),
In accordance with the signal of the perforation detector 27, it waits until the first frame of the film is set at a predetermined photographing position. Then, in the next step (223), the first motor drive circuit 46 is controlled so as to stop the first motor 24.
, A control signal is output to the display unit 3 in a subsequent step (224). Since a new film has just been loaded, "1" is displayed.

In step (225), it is checked whether or not the switch SW1 which is turned on in the first stroke of the shutter button 2 is turned on. If the switch SW1 has not been turned on yet, the process proceeds to step (226). It is checked whether the return switch 13 is on.
If it has not been turned on yet, the process returns to step (225), and the same operation is repeated. If it has been turned on, the process proceeds to step (181) in FIG.

In the above step (225), the switch SW
When it is detected that 1 is on, step (227)
Then, the output signal of the battery voltage detection circuit 44 is input to obtain information on the remaining capacity of the battery. Then, in the next step (228), it is determined whether or not the monitor 9 should be used based on the obtained information on the remaining capacity of the battery. Since the monitor 9 has relatively large power consumption,
When the remaining capacity of the battery is equal to or more than the predetermined amount, the monitor 9 is determined to be used, and the process proceeds to step (229). The image processing circuit 52 is activated, and the electronic image captured by the image sensor 51 is displayed as a visible image. Start displaying in real time. Thereafter, the process proceeds to step (231).

If the remaining capacity of the battery is less than the predetermined amount in step (228), the monitor 9 is not used and the process proceeds to step (230), the image processing circuit 52 is stopped, and the image pickup device is stopped. 51 and the monitor 9 are also stopped. Power supply may be stopped so that power consumption is minimized. Thereafter, the process proceeds to step (231).

In step (231), information is input from the distance measuring sensor 43 to obtain information on the distance to the subject. Further, a lens driving amount necessary for bringing the taking lens 1 into a focused state is calculated according to the obtained information on the distance to the subject. In the next step (232), a signal is output to the third motor drive circuit 48 to drive the focus adjusting lens according to the calculated lens drive amount, and the third motor 49 is driven. In the following step (233), information is input from the photometric sensor 42 to obtain luminance information of the subject. Then, step (23)
In 4), exposure such as shutter speed and aperture value is determined according to the obtained luminance information of the subject and the sensitivity information of the film 22 obtained in the above step (110).
At this time, it is also determined whether or not shooting should be performed using the flash device 56.

In the next step (235), the switch SW2 which is turned on by the second stroke of the shutter button 2
Is turned on. If it is not turned on yet, the process returns to step (225) and repeats the above-described flowchart. If it is turned on, the process proceeds to step (241) in FIG. The shutter 45 is controlled according to the exposure determined in 233). If you decide to use flash device 56,
A control signal is output so that the flash device 56 emits light. Thus, exposure of the film 22 is performed.
Regardless of whether the monitor 9 is used or not, a control signal is output to the image processing circuit 52 so that the image sensor 51 captures an image in synchronization with the exposure of the film.

In step (242), it is checked whether or not it is determined in step (228) that the monitor 9 is to be used. If it is determined that the monitor 9 is to be used, the flow advances to step (243). Then, in this step (243), a control signal is output to the image processing circuit 52 to switch the electronic image displayed on the monitor 9 in real time to a still image. This still image is an electronic image captured at a timing that can be regarded as substantially the same as the timing at which the exposure of the film 22 was performed in the step (241), and an image substantially matching the latent image exposed to the film 22. It is. In the following step (244), the image data currently displayed as a still image is transferred to the external memory 53 and stored as image data of the film. In the case where photographing is continued using the same film, this data is overwritten and stored every time exposure is performed and this step or a step (249) described later is passed. That is, the same film always stores the image data of one frame that was finally photographed.

In the next step (245), the system waits for the photographer to input the number of prints for printing. Here, the photographer can determine whether the photograph has succeeded or failed while looking at the electronic image displayed on the monitor 9, and can set the number of prints at the time of printing. In the next step (246), the process waits for the photographer to input a change in print aspect. The print aspect is set in advance by a print aspect setting switch (not shown). Here, the photographer can determine which aspect is best while viewing the electronic image displayed on the monitor 9, and You can change the aspect.

In step (247), various kinds of photographic data of the photographic frame including the number of prints and print aspect data are transferred to the memory 53 as photographic information data of the film and stored. In the case where photographing is continued using the same film as the data, exposure is performed and this step or a step (25) described later is performed.
0) is overwritten and stored each time. That is,
For the same film, the photographing information data of one frame which was finally photographed is always stored. Next step (24
In 8), a control signal is output to the image processing circuit 52 so that the image on the monitor 9 in the still image state in step (243) is displayed in real time. Thereafter, the process proceeds to step (251).

If it is determined in step (242) that the monitor 9 is not to be used, the process proceeds to step (249), where the electronic image data captured in step (241) is stored in the film. The image data is transferred to the external memory 53 and stored. The storage procedure is the same as that described in the above step (244). In the next step (250), various photographing data of the photographing frame is transferred to the external memory 53 as photographing information data of the film and stored. The storage procedure is the same as that described in step (247).

However, since the monitor 9 is not used, the captured image cannot be viewed on the monitor 9, and inputting the information of the number of prints and the change of the print aspect information may cause an erroneous input. This is banned because of its nature. Therefore, regarding the information of the number of prints, for example, information of one sheet as default data is stored,
As for the print aspect information, information set in advance by a print aspect setting switch (not shown) is stored as it is. Thereafter, step (251)
Proceed to.

In step (251), the first motor drive circuit 4 is driven to rotate the first motor 24 forward.
6 to output a control signal. This starts the winding of the film 22. In the next step (252),
A signal is output to the magnetic signal interface circuit 50 so that a recording current flows to the magnetic head 31 so that information is recorded on the magnetic track 30 on the film 22 in accordance with the stored photographing information data. In the following step (253), the recording of the photographing information is completed, and the control waits until the next photographing frame of the film is set at a predetermined photographing position according to the signal of the perforation detector 27. Then, in step (254), the first motor 24
Is output to the first motor drive circuit 46 so as to stop the operation. Then, in the next step (255), it is checked whether or not the shooting of the last frame of the film has been completed. If the shooting of the last frame has not been completed yet, the process returns to step (224), and the same operation is repeated.

When the photographing of the last frame has been completed, the process proceeds from step (255) to step (256), where a control signal is sent to the first motor drive circuit 46 so as to drive the first motor 24 in the reverse direction. Output. Thus, the rewinding of the film 22 is started. Then, the next step (2
In step 57), it waits until the film 22 is completely rewound into the film cartridge 21 in accordance with the signal of the perforation detector 27 and the like. The next step (258)
In, while reading the output signal of the film information reading circuit, the system waits for the information display panel 33 to reach a predetermined stop position indicating that the exposure has been completed. Then, in the next step (259), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24, and in the following step (260), the film is determined to be fully exposed. Therefore, the image data and the photographing information data corresponding to the film stored in the external memory 53 are deleted. Thereafter, the process proceeds to step (13) of FIG. 7 and waits for the removal of the film 22.

If it is determined in step (117) of FIG. 7 that the information of the film photographing state is not unexposed, it is determined that partial exposure has occurred, and that step (26) in FIG.
Proceed to 1).

In step (261), the first motor drive circuit 4 is driven to rotate the first motor 24 forward.
6 to output a control signal. Thus, the feeding of the film 22 is started. In the next step (262)
In order to obtain photographing information recorded on the magnetic track 30 on the film 22, signal input from the magnetic signal interface circuit 50 is started. Then, the next step (26)
In 3), based on the determination that the frames on which the photographic information is recorded on the magnetic track 30 have been photographed and the frames that have not been recorded are unexposed frames, it is checked whether the frames are unexposed frames one by one while feeding the film 22. If the checked frame is not an unexposed frame, the flow advances to step (264).

In step (264), it is checked whether the frame that has been checked for an unexposed frame is the last frame of the film. If not, the flow returns to step (263) to check again whether the next frame is an unexposed frame.
If an unexposed frame is detected here, step (26)
The process proceeds to 5) and waits until the detected unexposed frame is set at a predetermined exposure position in accordance with the signal of the perforation detector 27. In the following step (266), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. Then, the next step (2
In 67), the photographing information of the last exposed frame which is one frame before the detected unexposed frame is decoded, and the decoded information is stored in the external memory 5.
3 is compared with the photographing information data of the film that has been rewound halfway in the past. The storage of the shooting information data of the film to be rewound halfway will be described later.

In step (268), if there is matched data as the collation result, step (269)
Then, the output signal of the battery voltage detection circuit 44 is input to obtain information on the remaining capacity of the battery. Then, in the next step (270), it is determined whether or not the monitor 9 should be used based on the obtained information on the remaining capacity of the battery. Since the monitor 9 has relatively large power consumption,
When the remaining capacity of the battery is equal to or more than the predetermined amount, the process proceeds to step (271) assuming that the monitor 9 is used, and is stored in the external memory 53 in association with the stored shooting information data of the film that has been rewound halfway. The image data is transferred to the image processing circuit 52. In step (272), a control signal is output to the image processing circuit 52 to display the transferred image data on the monitor 9.

Thus, the user can know what the last photographed image of the currently loaded film was. When this step ends, the process returns to the step (224) in FIG.

If there is no matched data in the step (268), and if the use of the monitor 9 is not selected in the step (270), the process proceeds to the step (273). In this case, no image is displayed or cannot be displayed. Therefore, a control signal is output to the image processing circuit 52 so that the image is not displayed on the monitor 9. When this step ends, the process returns to the step (224) in FIG.

If the last frame of the film is detected in step (264), the flow advances to step (274) to control the first motor drive circuit 46 to rotate the first motor 24 in the reverse direction. Is output. Thus, the rewinding of the film 22 is started. In the next step (275), the process waits until the film 22 is completely rewound into the film cartridge 21 according to the signal of the perforation detector 27 and the like. Then, the next step (27
In step 6), while reading the output signal of the film information reading circuit 34, the process waits for the information display panel 33 to reach a predetermined stop position indicating that the exposure has been completed. Subsequent steps (27
In 7), a control signal is output to the first motor drive circuit 46 so as to stop the first motor 24. Thereafter, the process proceeds to step (113) and subsequent steps in FIG.
Wait for 2 to be removed.
