Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera in which a film rewound in the middle of an unphotographed frame is loaded and a film is continuously photographed on the unphotographed frame.

[0002]

2. Description of the Related Art Information about the number of photographed frames is recorded in a magnetic recording section on a film when the film is rewound midway while leaving an unphotographed frame, and when the film is loaded again, the photographed frame of the magnetic recording section is recorded. A camera is known in which numerical information is read and the film is wound up by the number of frames to prevent double exposure of frames that have already been photographed.

Further, when the film is rewound midway while leaving unphotographed frames, information on the number of frames already photographed and the IS set by the photographer.
O information and DX information of film are stored in the EEPROM of the camera.
The DX information is read when the film is loaded and compared with the DX information recorded in the EEPROM,
If the two match, it is determined that the film is a rewind film on the way and the film is wound up by the number of photographed frames recorded in the EEPROM, and the ISO information recorded in the EEPROM is read and set. Known (for example, JP-A-3-116034)
Reference).

[0004]

By the way, in the former camera described above, the setting information of the camera such as the exposure correction value and the photographing mode at the time of reloading the midway rewinding film as described above is the same as that of the film previously set. It may have been changed from the setting information when the was shot. If the user wants to continue shooting the film with the previous setting information, the setting information must be manually set again for each setting information, and the operation is troublesome, so that a photo opportunity may be missed. Further, it is troublesome to record the setting information of the camera for each film when rewinding the film halfway. For example, when shooting black and white film and color film alternately while rewinding midway, different exposure correction values may be set for the black and white film and color film. In such a case, load the film. The exposure compensation value for the loaded film must be reset each time. Also, in general, the one-shot AF mode, in which the focus is locked once the shooting lens is in focus when shooting a still subject, is suitable for continuous shooting, in which automatic focusing is always performed when shooting a moving subject regardless of whether the subject is in focus. The mode is suitable. When alternating low-sensitivity film for still subject shooting and high-sensitivity film for moving subject shooting while rewinding halfway, set the focus mode appropriate for the loaded film each time the film is loaded. There must be. As for the setting information of other cameras, there is an optimum setting state depending on the film used, so for the film rewound midway while leaving the unrecorded frame, the setting information at the time of previous shooting must be reproduced. I won't.

Further, in the latter camera described above, whether or not the film is a rewind film on the way is identified only by the DX information. Therefore, when a plurality of films having the same DX information are alternately used, the individual identification is made. Otherwise, incorrect ISO information may be set.

Further, in any of the above-mentioned conventional cameras, a film that has been rewound midway in one camera body is loaded in another camera body, shot, and then rewound midway, and then the first camera body is rewound. It is not possible to alternately rewind a plurality of films with a plurality of camera bodies in the middle, such as loading and shooting.

An object of the present invention is to provide a camera which automatically resets the setting state of various information of the camera to the same state as the previous shooting of the film when reloading the film taken out halfway.

The set various information can be confirmed by the LCD panels 55 and 57. When the information setting button 53 is pressed again, the information setting mode is released.

Next, the operation of the embodiment will be described by taking an exposure correction value as an example of camera setting information. 9 to 12
3 is a flowchart showing a control program of a microcomputer. When the cartridge chamber lid 41 is closed and the lid opening / closing detection switch SW1 is closed while the power switch (not shown) of the camera 1 is turned on, an interrupt occurs in the microcomputer of the controller 5, and the microcomputer causes the cartridge chamber shown in FIG. Execute the lid close routine. In step 1, it is confirmed by the cartridge loading state detection switch SW2 whether or not the film cartridge 3 is loaded in the cartridge chamber 43. If it is loaded, the process proceeds to step 2, otherwise the process is ended. In step 2, the setting information including the number of shots information and the exposure correction value is read from the EEPROM 3c of the cartridge 3. The number of shots is recorded for the midway rewind film, and the number of sheets 0 is recorded for the unused film. In step 3, the drivers DR1 and DR2 and the motors M1 and M2 feed and wind the film 2 to set the unphotographed frame to a predetermined photographing position based on the read information on the number of photographed images, and the number of photographed images to the LCD panel 55. , 57. At this time, in the case of an unused film, the first frame is set at a predetermined photographing position. In the case of a halfway rewind film, the fact is displayed on the LCD panels 55 and 57. In the above embodiment, the information about the number of shots and the setting information are recorded in the EEPROM 3c of the cartridge 3 and the information about the number of shots and the setting information are read out before the film 2 is sent out. The magnetic recording section 2c of the reader section may be used for recording. In that case, the feeding of the film 2 may be started first, and the number-of-images information and the setting information of the leader section may be read during the feeding to set the unphotographed frame at a predetermined photographing position. Next, in step 4, the setting information including the exposure correction value is reset in the camera 1 and stored in the EEPROM 4. Since setting information is not recorded in the case of an unused film, various information is not reset, and the setting state before loading the unused film is the EEPROM 4
Is stored. In step 5, it is determined whether or not the release button 54 is half-pushed by the switch SW4, and if it is half-pushed, the process proceeds to step 6. In step 6, photometry is performed by the photometric device 10, exposure calculation is performed based on the subject brightness of the detection result and the exposure correction value set in the exposure correction routine described later, the exposure control value is determined, and the LCD panel 55, 57 is displayed. At the same time, the distance measuring device 11
The image pickup distance is measured by, the driver DR3 is controlled based on the measured image pickup distance, and the focus of the focus matching lens is adjusted by the motor M3.

When the release button 54 is fully pressed and the switch SW5 is closed, an interruption occurs in the microcomputer of the controller 5, and the microcomputer executes the release routine shown in FIG. Step 1
1, the shutter 45 is controlled to perform the photographing operation of the film 2. In step 12 after photography, the film DR2 is wound up by one frame by the driver DR2 and the motor M2.

When the information setting button 53 is operated and the information setting switch SW3 is closed, an interruption occurs in the microcomputer of the controller 5, and the microcomputer executes the exposure correction routine shown in FIG. In step 21, the current exposure correction value is displayed on the LCD panel 5.
5, 57 are displayed. In the following step 22, the pulse generator 8 detects the rotation amount and the rotation direction of the command dial 56, and the exposure correction value is changed according to the rotation amount and the rotation direction of the detection result based on the current exposure correction value. It is displayed on the LCD panels 55 and 57. In step 23, it is determined whether or not the information setting button 53 is operated again to close the switch SW3. When the information setting switch SW3 is closed, the process proceeds to step 24, and the changed exposure correction value is EEPR.
Store in OM4. In this embodiment, the exposure correction value has been described as an example of the setting information of the camera 1, but the information of all the cameras such as the aperture value, the shutter speed, and the shooting mode can be set by the method described above.

When the rewind button 58 is operated and the switch SW6 is closed, an interrupt is generated in the microcomputer of the controller 5, and the microcomputer executes the rewind routine shown in FIG. Step 31
At the EEPROM 3c of the film cartridge 3
The setting information of the camera 1 including the information on the number of shots and the exposure correction value is written in. In the following step 32, the film 2 is rewound onto the cartridge 3 by the driver DR1 and the motor M1. When the number-of-photos information and the setting information are recorded in the magnetic recording unit 2c of the leader unit of the film 2, the rewinding of the film 2 is started first and the magnetic recording unit 2c of the leader unit captures images during the rewinding. The number information and the setting information may be recorded.

It should be noted that it is more convenient to record the information on the number of shots and the setting information in the leader portion of the film 2 so that the information can be read out at the time of reloading. Further, in the above-described embodiment, the example in which the information on the number of shots and the setting information are recorded in the EEPROM 3c built in the film cartridge 3 is shown. However, in this way, the information on the number of shots and the setting information are read from the cartridge 3 to the film 2 one by one at the time of reading. Easy to use because there is no need to pull out.

-Modification of Embodiment of the Invention- Magnetic recording section 2c of film 2 in which film identification information for identifying individual films and film number information are associated with each other.
Or write to the EEPROM 3c of the cartridge 3,
The film identification information and the setting information may be associated and recorded in the EEPROM 12 of the camera body 1a. In this case, when the cartridge 3 is loaded, the film identification information is read from the magnetic recording unit 2c or the EEPROM 3c, the setting information corresponding to the read film identification information is read from the EEPROM 12, and is reset in the camera 1. By doing this, the magnetic recording portion 2c and the EE
The storage capacity of the PROM 3c can be reduced, which is advantageous when the capacity of setting information becomes enormous.

In FIGS. 13 and 14, E of the film cartridge 3 is associated by associating the film identification information with the information on the number of shots.
The EEPR of the camera body 1a is written in the EPROM 3c by associating the film identification information with the setting information.
It is a flow chart which shows a control program at the time of recording on OM12. With these flowcharts, the operation of the modified example of the above embodiment will be described by taking the exposure correction value as an example of the setting information of the camera. The release routine and the exposure correction routine are the same as those in the above-described embodiment shown in FIGS. When the cartridge chamber lid 41 is closed and the lid opening / closing detection switch SW1 is closed while the power switch (not shown) of the camera 1 is turned on, an interrupt occurs in the microcomputer of the controller 5, and the microcomputer causes the cartridge chamber shown in FIG. Execute the lid close routine. In step 41, it is confirmed by the cartridge loading state detection switch SW2 whether or not the film cartridge 3 is loaded in the cartridge chamber 43. If it is loaded, the process proceeds to step 42, and if not, the process ends. In step 42, the film identification information and the number of shots information is read from the EEPROM 3c of the cartridge 3. The film identification information and the number of shots are recorded in the case of a halfway rewind film, and the film identification information is not recorded and the number of shots is 0 in the case of an unused film. In step 43, the drivers DR1 and DR2 and the motor M
The film 2 is fed out and wound up by means of 1 and M2, the unphotographed frame is set at a predetermined photographing position based on the read photographed number information, and the number of photographed images is displayed on the LCD panels 55 and 57. At this time, in the case of an unused film, the first frame is set at a predetermined photographing position. In the case of a midway rewinding film, LCD panel 5
5, 57 are displayed. When recording the film identification information and the number-of-images information in the magnetic recording section 2c of the leader section of the film 2, the feeding of the film 2 is started first,
The film identification information and the number-of-photographed-image information of the leader section may be read out during the sending out to set the unphotographed frame at a predetermined photographing position. Next, at step 44, the setting information including the exposure correction value corresponding to the film identification information is read from the EEPROM 12. When the loaded film is an intermediate rewinding film, the identification information of the film and the setting information of the camera at the time of shooting are stored in the EEPROM 12 in association with each other, so that they are read out. If the loaded film is an unused film, this process is not executed because there is no film identification information. In step 45, the setting information including the exposure correction value is reset in the camera 1, and
Store in EEPROM 4. Since setting information is not recorded in the case of an unused film, various information is not reset, and the setting state before loading an unused film is stored in the EEPROM 4. In step 46,
It is determined by the switch SW4 whether or not the release button 54 is half-pushed, and if half-pushed, the process proceeds to step 47. In step 47, photometry is performed by the photometric device 10, exposure calculation is performed based on the subject brightness of the detection result and the exposure correction value set in the above-described exposure correction routine, the exposure control value is determined, and the LCD panel 55, 57 is displayed. At the same time, the distance measuring device 11 measures the shooting distance, controls the driver DR3 based on the measured shooting distance, and adjusts the focus of the focus matching lens by the motor M3.

When the rewind button 58 is operated and the switch SW6 is closed, an interrupt is generated in the microcomputer of the controller 5, and the microcomputer executes the rewind routine shown in FIG. Step 51
At the EEPROM 3c of the film cartridge 3
The film identification information and the number of shots information are written in. In addition,
The identification information is randomly recorded for the film that is rewound midway for the first time, but the previously recorded identification information is continuously used for the film that has been rewound midway. The identification information may be recorded when the film is manufactured. In the following step 52, E
The setting information of the camera 1 is read from the EPROM 4, and the setting information is stored in the EEPROM together with the film identification information.
12 is stored. At step 53, the film 2 is rewound onto the cartridge 3 by the driver DR1 and the motor M1. When the film identification information and the information on the number of shots are recorded in the magnetic recording section 2c of the leader section of the film 2,
The rewinding of the film 2 may be started first, and the information about the number of shots and the setting information may be recorded in the magnetic recording section 2c of the reader section during the rewinding.

FIG. 15 shows an information setting operation of the camera when two films are alternately photographed in the modification of the above embodiment. An unused film 1 is loaded in the camera, and various kinds of information such as the exposure correction value and the shooting mode are set in the setting state 1 and shooting is performed. Film 1 is rewound in the middle of shooting, and then unused film 2 is loaded. Then, various kinds of information are changed to the setting state 2 suitable for the film 2, the image is taken, and the film 2 is rewound after the image is taken. After that, when the film 1 that was previously rewound midway is reloaded, the camera sets the state 1 at the time when the film 1 was rewound first during shooting.
Is automatically reset to.

FIG. 16 shows a camera information setting operation when two films are alternately photographed by a conventional camera.
An unused film 1 is loaded into the camera, various information of the camera is set to the setting state 1, and shooting is performed. Film 1 is rewound in the middle of shooting, and then unused film 2 is loaded. Then, various information is set in a setting state 2 suitable for the film 2.
Change to, shoot, and rewind film 2 after shooting. After that, the film 1 which was previously rewound midway
When reloaded, the camera remains in setting state 2 which was set for film 2.

Next, consider a case where two films are alternately photographed by two camera bodies. FIG. 17 shows the information setting operation of the camera when two films are alternately photographed by two cameras, and FIG. 18 shows the stored contents of the camera body and the film. Further, FIG. 19 shows changes in the recorded contents of the film. In a system in which the camera body 1 and the camera body 2 write / read only the setting information to / from the film 1 and the film 2 at the time of rewinding / reloading the film midway, the setting information is stored in the same memory. Therefore, the setting information of the camera body that last rewound the film is stored in the film. Now, as shown in FIG. 19, the unused film 1 is loaded into the camera body 1, and up to 8 frames are photographed in the setting state 1, the film is rewound midway and reloaded into the camera body 2. At this time, since the setting state 1 is stored in the film 1, the camera body 2 is in the setting state 1. Therefore, various information of the camera body 2 is changed to the setting state 2, and up to 15 frames are photographed and rewinding is performed halfway, and the film 1 is re-displayed.
When the camera body 1 is reloaded, the camera body 1 enters the setting state 2.
That is, when rewinding / reloading the film on the way, the camera body 1 and the camera body 2 only send the setting information to the film 1,
In the system for writing / reading the film 2, if the camera body is exchanged and the film rewound midway is reloaded, another camera body is set.

20 and 21 show a camera system in which such drawbacks are improved, and FIG. 22 shows an information setting operation of the camera system. In this system, when the film is rewound / reloaded in the middle of the film, the camera body 1 and the camera body 2 associate the body identification information with the setting information to write / read the film 1 and the film 2. As a result, the setting information of one camera body that is stored will not be overwritten by the setting information of that camera body when the other camera body rewinds midway. On the other hand, the setting information when the film is rewound during shooting can be reset. Now, as shown in FIG. 22, the unused film 1 is loaded into the camera body 1 and up to 8 frames are photographed in the setting state 1, the film is rewound midway and reloaded into the camera body 2. At this time, since the film 1 has not been rewound midway in the camera body 2, the setting state of the camera body 2 is not changed to the setting state 1. Next, when the camera body 2 is set to the setting state 2 and up to 15 frames are photographed, rewinding is performed halfway and the camera body 1 is reloaded, the camera body 1
Becomes the setting state 1 when the film 1 is rewound to 8 frames.

In the system shown in FIGS. 20 and 21, the body identification information and the setting information are associated with each other when the film is rewound / reloaded in the middle of the film, and the film is written / read out. However, as shown in FIG. In addition to writing / reading the film identification information to / from the film (only the body which is initially rewound midway is written or written at the time of film manufacturing), the film identification information and the setting information are associated with each other, and the storage means on the camera body side You may make it read / write in. By doing this, the camera body reads the film identification information from the film when reloading the film,
By selecting the setting information stored in the storage means in combination with the film identification information, the setting state of the camera can be returned to the setting state when the camera body rewinds the film during shooting.

In order to save the memory capacity of the storage means, the film identification information and the setting information may be erased by the camera body at the time when all the frames of the film have been photographed. Alternatively, the film identification information and the setting information written in the storage means may be erased in order from the oldest writing time when the memory capacity is full.

Although the exposure correction value is taken as an example of the camera setting information in the above-described embodiment and its modification, the present invention can be applied to setting information other than the exposure correction value. Generally, the setting information of the camera is changed according to the subject to be photographed, for example, stillness / movement, low brightness / high brightness, but the type of film used, for example, color / black and white, negative / positive, infrared / visible light. The application, manufacturer, resolution, low sensitivity / high sensitivity, and soft / hard tone are also changed according to the shooting target. That is, since the film and camera information settings are closely related via the shooting target, the camera setting information is stored when the film is rewound midway, and the camera setting information stored when the film is rewound midway is reloaded. By reading out and automatically resetting, the operability at the time of shooting can be improved.

Here, an example of setting information other than the exposure correction value is shown. (1) Setting information related to automatic focus adjustment a) Focus mode (one-shot AF / continuous AF / manual focus) setting. One-shot AF and low-sensitivity film are suitable for stationary subjects. On the other hand, continuous AF and high-sensitivity film are suitable for moving subjects. b) Setting of focus adjustment amount (offset amount of each person's favorite added to the focus position at the time of automatic focus adjustment) In some cases, it is desired to set this amount to be different depending on the film type (film spectral sensitivity). c) Setting of response priority AF / precision priority AF Precision priority AF and low sensitivity film are suitable for stationary subjects. On the other hand, the response priority AF and the high sensitivity film are suitable for a moving subject. d) Setting of release priority AF / focus priority AF. The release priority AF is a mode in which the shutter operation is performed by fully pressing the release button regardless of the focus adjustment state, and the focus priority AF is a mode in which the shutter operation is prohibited until the focus is achieved even when the release button is fully pressed. Focus-priority AF and low-sensitivity film are suitable for stationary subjects, and release-priority AF and high-sensitivity film are suitable for moving subjects. e) Setting of size of focus area (focus detection area) The wide focus area is a mode in which focus detection is performed in a relatively wide area, and the spot focus area is a mode in which focus detection is performed in a relatively narrow area. It is suitable to use a low-sensitivity film for stationary subjects to focus on the spot focus area, and a high-sensitivity film for moving subjects to prevent the subject from moving out of the focus detection area in a wide focus area. It is better to do. f) Setting the position of the focus area When there are a plurality of focus areas, it is desired to set which focus area is used to perform AF (automatic focus adjustment) depending on the composition of the subject to be photographed. For example,
When the films are separately used for vertical position shooting and horizontal position shooting, the focus detection position is naturally different. In the case of person shooting, since the face is on the upper side of the screen, it is desirable to set the focus detection position to the upper side of the screen regardless of vertical position shooting and horizontal position shooting. g) Setting the focus area position specification method When there are multiple focus areas, the camera body automatically determines which focus area to use for AF (automatic focus adjustment). There are a method of manually specifying by the photographer and a method of specifying according to the direction of the line of sight of the photographer. For a stationary subject, it is better to use a low-sensitivity film and manually specify the focus position to determine the focus position according to the photographer's intention. On the other hand, for a moving subject, it is better to use a high-sensitivity film and automatically specify the composition.

(2) Metering-related setting information h) Setting of metering area (center-weighted metering, spot metering) For a stationary subject, a low-sensitivity film is used to determine the metering position for spot metering by the photographer's intention. Better. On the other hand, for a moving subject, it is better to use a high-sensitivity film and focus on composition with a central emphasis. (3) Setting information related to exposure mode i) Shutter speed priority / Aperture priority / Program (automatically determines aperture value and shutter speed according to brightness) / Manual setting It is better to take advantage of the blur. On the other hand, for a moving subject, it is better to use a high-sensitivity film to prioritize shutter speed or manually prevent image flow. Alternatively, it is better for the program to always focus on the photo opportunity with proper exposure. (4) Setting information related to winding mode j) Setting of continuous shooting mode / single frame winding mode (one frame shooting by full-press, one frame winding) For a stationary subject, use a low-sensitivity film in one frame winding mode. It is better to shoot carefully. On the other hand, it is better to continuously shoot a moving subject in a continuous shooting mode using a high sensitivity film. (5) Strobe-related setting information k) Strobe shooting / normal shooting settings It is better to use a low-sensitivity film for normal shooting on high-brightness subjects. On the other hand, it is better to use a high-sensitivity film for stroboscopic photography for a low-luminance subject. (6) Setting information related to data imprinting 1) Setting with / without data imprinting It is suitable for printing without data imprinting and positive film, and for recording with data imprinting and negative film. Are suitable.

(7) Other setting information m) Setting of whether or not the tongue is left when the film is rewound. When developing by yourself, it is suitable to use the tongue and tongue with black and white film, and when developing at the photo lab. For this, a color film with no leftover is suitable. n) Setting of the exposure change step number during exposure bracket shooting Since the negative film has a wide latitude, the step number should be rough. On the other hand, since the positive film has a narrow latitude, the number of steps should be narrow. o) Setting the step (number of steps) when inputting shutter speed / aperture value Since the negative film has a wide latitude, the number of steps should be coarse. On the other hand, since the positive film has a narrow latitude, the number of steps should be narrow. p) Setting of shutter speed / aperture value display step (number of steps) Since the negative film has a wide latitude, the number of steps should be coarse. On the other hand, since the positive film has a narrow latitude, the number of steps should be narrow. q) Shutter speed and aperture setting when manual exposure is set Change according to film sensitivity. r) Shutter speed setting when shutter speed is prioritized Vary according to film sensitivity. s) Aperture value setting when aperture is prioritized Change according to film sensitivity.

In the above-described embodiment and its modification, the setting information of the camera is automatically stored when the film is rewound midway. However, the current setting information is displayed on the display when the film is rewound midway. The user may be allowed to manually select whether or not to store them. This makes it possible to deal with the case where automatic resetting of information is not necessary when reloading the halfway rewind film. In that case, the default data may be recorded on the film at the time of rewinding on the way, and the camera side may not automatically reset when the default data is received. Further, the setting information stored in the film may be read when the halfway rewinding film is reloaded, and the setting information may be temporarily displayed on the display to allow the user to manually select whether or not to reset. . Also in this case, the same effect as above can be obtained.

In the above-described embodiment and its modification, the setting information of the camera is automatically stored when the film is rewound midway. However, the setting information of the camera is automatically stored at any time during the use of the film in accordance with the manual operation of the photographer. The setting information of the camera at the time may be stored. As a result, the setting information of the camera at the time of shooting several frames before the midway rewinding can be reset when the midway rewinding film is reloaded.

In the above-described embodiment and its modification, the setting information stored in the film is automatically reset in the camera when reloading the midway rewinding film, but the information is not automatically reset in reloading. , At any time after reloading, the setting information stored in the film is read according to the manual operation of the photographer, the information is temporarily displayed on the display unit, and the user can manually set whether or not to reset the setting information. You may make it select by. By doing so, it is possible to deal with the case where the user wants to take a picture in the information setting state of the camera before the midway rewind during the shooting after the reloading of the midway rewind film.

The setting information that is stored when the film is rewound midway and is automatically reset when reloading is not limited to one, but a plurality of setting information, such as the photometric mode and the exposure correction value in the case of photometry, and the automatic focus adjustment. A combination of a plurality of mutually related setting information such as selection of focus mode and selection of release priority / focus priority may be stored / reproduced. Further, at the time of storage or reproduction, such information may be selected and stored / reset according to a manual operation. With this configuration, when the midway rewinding film is reloaded, a plurality of setting information can be automatically reset at once, and the operability is remarkably improved as compared with the case of manual setting. In the above-described embodiment, the magnetic recording portion 2c of the film 2 or the EEPR of the film cartridge 3 is used.
Although the information is recorded in the OM 3c, the film cartridge may be provided with a magnetic recording portion to record the information.

In the configuration of the above embodiment, the magnetic recording section 2c and the EEPROMs 3c and 12 are the recording means, and the information setting button 53, the information setting switch SW3, the command dial 56 and the pulse generator 8 are the information setting means.
The controller 5 and the magnetic head 7 constitute information writing means and information resetting means, respectively.

As described above, according to the present invention, the setting information of the camera is written in the storage means of the film or film cartridge when a predetermined operation is performed, and the film or the film cartridge is loaded when the film is loaded in the camera. Since the setting information recorded in the memory means is read out and reset to the camera, when the film taken out halfway with the unrecorded frame left is reloaded, The setting state of the camera is automatically and accurately reset, and the remaining unphotographed frames can be continuously photographed in the same setting state as before, and the operability is improved. Further, when a predetermined operation is performed, the identification information unique to the camera and the setting information of the camera are associated with each other and written in the storage means of the film or film cartridge, and when the film is loaded in the camera, the storage means of the film or film cartridge is stored. The recorded identification information and the setting information are read out, and when the read identification information matches the identification information unique to the camera, the read setting information is reset in the camera. Even if you take pictures alternately with the camera bodies, the settings when the film was taken with each camera body are automatically and accurately reset to improve the operability. Further, when a predetermined operation is performed, the identification information unique to the film or the film cartridge and the setting information of the camera are associated with each other and written in the storage means, and when the film is loaded in the camera, the unique identification information from the film or the film cartridge is obtained. Since the setting information corresponding to the read out identification information is read out from the storage means and reset to the camera, even if a plurality of films are alternately photographed by a plurality of camera bodies, each film is previously photographed. The setting state at the time of doing is automatically re-set accurately and the operability is improved. When writing is selected by the writing selection member, the setting information of the camera is written in the storage means, so when the film rewound midway while leaving the unphotographed frame reloaded, It is possible to arbitrarily select whether or not to re-set the setting information in the camera. Further, when the resetting is selected by the resetting selection member, the setting information stored in the storage means is reset in the camera. When reloaded, it is possible to arbitrarily select whether or not to reset the setting state at the time of previous photographing to the camera. Since the information is written in the storage means when the film is rewound, the setting information of the camera can be surely recorded on the halfway rewind film. Further, since the information is written when the operation member is operated, it is possible to record the setting information of the camera at the time of photographing an arbitrary frame and reset them when reloading the film taken out halfway.
