Abstract

PURPOSE:To improve processing function of a printer by recording information in a film in the case when exposure is carried out properly for standard light exposure printing for all frames of a roll of film used for photographing. CONSTITUTION:CPU 1 lowers Fft flag of the information regarding a standard light exposure printing to zero at the time of AE mode and AE is NG in the case a strobe 14 is in OFF state. The CPU 1 lowers the Fft flag to zero at the time of automatic strobe mode and light modulation NG in the case the strobe 14 is in ON state. In all other cases, the Fft is kept 1. Here, Fft=0 corresponds to the judgement that proper exposure control cannot be carried out. In the case judgement result shows that Fft=1 for all the frames, Fft=1 is recorded in the film by a magnetic recording part 6. Consequently, a printer does not need to read out the information regarding the standard light exposure printing for every frame and can carry out printing process for all the frames of each roll of film.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for discriminating an exposure condition at the time of photographing by a camera and recording the photographed information on a film to instruct a method for producing a print photograph, and more particularly to a method for recording the information. .

[0002]

2. Description of the Related Art Conventionally, when a print is obtained from a developed negative film by a printing process of an automatic printer,
By calculating the integrated transmission density of the entire shooting frame from the transmitted light for each shooting frame, determining the exposure amount for printing and performing the printing process, it is possible to correct variations in exposure and color areas during shooting to obtain an appropriate density. I was trying to get a color balanced print.

However, since such an autoprinting method is based on the premise of uniform print finishing, it cannot reflect the intention of the photographer to draw an image. Even if a photograph is properly exposed to a person when the picture is taken with the camera, the amount of exposure that is affected by the high-intensity areas around the person is determined by auto printing during printing, and the person on the print is shaded. There were cases where it became (blacked out).

In order to deal with the problem of image sticking by such an auto printer, the "camera and photographic printer" of Japanese Patent Laid-Open No. 3-72338 has a "correction unnecessary mark" recorded on a film at the time of photographing, and the printer If the mark is identified, the standard printing exposure amount (normally controlled negative exposure amount required for photographic printing with proper density and color balance without performing automatic correction for each frame by the auto printer) There is disclosed a method in which it is determined whether or not printing is to be performed by an auto printer based on the presence / absence of a mark by performing printing according to the amount).

Further, in Japanese Patent Laid-Open No. 4-319933, "Photographic printing method", when a camera having an AE function with high exposure accuracy is used, the "exposure amount is determined by a multipoint photometric method" at the time of shooting. , Or information indicating that the exposure amount was determined from the photometric value when the subject was focused by autofocus "was recorded on the film with a bar code, etc., and the printer discriminates whether or not there is information recording In this case, the processing is performed for each frame, and when the information is recorded, the integrated exposure density of all the photographed frames of one film is obtained, and the printing exposure amount is determined based on the average value. Has been done. The exposure amount in the case where this information is recorded corresponds to the reference printing exposure amount in the preceding example,
Hereinafter, with respect to auto printing, a printing method using such a standard exposure amount of exposure will be referred to as a reference exposure amount baking method, and the printing by this will be referred to as reference exposure amount baking.

Further, in Japanese Patent Laid-Open No. 5-127277, "Printed Photographing Method", there is a need for a small amount of correction of a printing exposure amount due to variations in exposure, and a recent camera or the like that performs highly accurate exposure control. In this case, for a shooting frame whose exposure is properly controlled on the camera side, identification information is recorded in a bar code or the like in the information recording section of each frame, and on the printer side, the identification information is read for each frame and the information is recorded. The frame is recorded with the identification information, such as the automatic exposure that corrects the fixed exposure amount by the film sensitivity difference and performs the timer exposure for a predetermined time, and the frame without the identification information is corrected. It is disclosed that the presence / absence of a print is determined and the exposure method for printing is switched. In this case as well, the processing of the frame in which the identification information is recorded as that the exposure is properly controlled belongs to the category of the reference exposure amount printing.

[0007]

However, in the above-mentioned conventional method, even when all the frames of one film are properly exposed by the camera, for example, the same information indicating the proper exposure is recorded for each frame. There must be. In addition, since the same information is read and discriminated for each frame by a reading device such as a bar code reader on the printer side, the problem that the information recording portion of the film cannot be effectively utilized and the processing capability of the printer is reduced. There is a problem to let.

Recently, the performance of the camera itself has been improved rapidly, and in particular, exposure control is performed so that the main subject is properly exposed by AF control and AE control. In the case of a camera, for example, the number of AF points for AF is increased, and the photometry area is also changed to correspond to the AF points. Focusing is performed on the main subject to perform photometry corresponding to the main subject, and exposure control is performed so that the negative density of the main subject becomes appropriate. Since all the frames of one film shot in this way will be properly exposed,
The number of cases of correction is decreasing more and more. By recording the same information for each frame as described above, the effective use of the information recording section of each frame of the film is hindered and the processing capacity of the printer is reduced. The problem is becoming more prominent.

In view of the above-mentioned problems, the object of the present invention as set forth in claim 1 is to cope with a camera which has recently been made highly functional and highly accurate, so that all of the one film taken can be used.

An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of the present invention. FIG. 1 is a flowchart of information recording processing of a camera according to the first embodiment of the present invention. FIG. 2 is a block diagram of a circuit configuration of a camera used in the embodiment shown in FIG. FIG. 3 is a plan view of a film used in the camera shown in FIG.

The camera used in this embodiment shown in FIG.
The CPU 1 controls the entire operation, display processing, etc., and the photometry unit 2 is provided with multi-division photometry and spot photometry in which a spot photometry area is arranged at the center of an image area sensor or the like, and its output is measured. CPU as data
You are entering 1. The distance measuring unit 3 measures the distance to the object and inputs the distance measuring data to the CPU 1.
AF control is performed according to the distance measurement data processed by.

The exposure control circuit section 5 controls the exposure on the basis of the exposure control information processed by the CPU 1 in accordance with the photographing information such as the input photometric data. The magnetic recording unit 6 is a recording unit of a film 30 as shown in FIG. 2 via a magnetic head, a reader unit recording area 31 and recording areas 31a for each frame.
Information such as reference exposure amount printing is recorded in c ... n.

The film 30 is fed and rewound by the film 3
The perforation 32 of 0 is detected by the perforation detecting unit 7 such as a photo reflector to confirm the film position, and the film feeding unit 8 drives the film feeding motor. On the display unit 9 such as an LCD, the state of the camera, the input data at the time of information input, the exposure control value, the number of frames, etc. are displayed under the control of the CPU 1.

In the photographing mode setting section 10, the aperture priority A
Any one of the shooting modes such as E, shutter priority AE, program AE, and manual is selected and set. When the manual mode is set by the shooting mode setting unit 10, the manual setting unit 11 inputs the controlled aperture value and shutter speed.

Strobe unit 14 that operates during strobe photography
Is an auto mode that automatically controls the flash output,
It has a manual mode in which the light emission amount is set manually. The dimming detection unit 12 determines whether or not dimming control has been performed, whether or not the prescribed light amount has been reached during strobe light emission. In addition, SW1 1 to start photometry and AF with the first stroke
5. A release switch composed of SW216 which starts exposure in the second stroke is provided.

Next, a first embodiment of an information recording method performed by using the camera having the above-mentioned structure will be described with reference to FIG. First, the completion of loading the film 30 is confirmed (S10
1), auto-loading (AL) is performed by the operation of the film feeding unit 8 and the film 30 is driven to a predetermined position where photography can be performed and stopped (S102). Number of frames N
Is set to 1, and the Fft flag of the information regarding the reference exposure amount printing to be recorded in the film reader unit 31 is set to 1 (S103). Any one of the shooting modes is set by the shooting mode setting unit 10, and this is repeated until SW1 is pressed (S104). SW1 15 is ON
Then (S105), distance measurement is performed by the distance measurement unit 3, the result is converted into a lens drive amount, and the AF control unit 4 performs AF.
Is performed (S106). Subsequently, photometry is performed by the photometry unit 2 (S107). These are repeated until SW2 is pressed. When the SW216 is turned on (S108), the exposure control circuit unit 5 controls the exposure to expose the film 30 (S109).

The following S110 to S116 are the processes for judging the Fft flag. First, when the strobe is OFF (NO in S110), the Fft flag is set to 0 (S116) in the AE mode and when AE is NG (NO in S112 and NO in S113). If the flash is turned on in S110 (YES in S110)
At the time of strobe auto and dimming failure (S114)
If NO in step S115 and NO in step S115), the Fft flag is set to 0 (step S116). In all other cases, Ff
It remains t = 1. Here, the meaning of Fft = 0 corresponds to the determination processing that proper exposure control is not performed. Therefore, when performing manual shooting in which both the aperture and shutter speed are manually set, the fact that the Fft flag is set to 1 as in S112 and S114 is that manual shooting is performed during AE shooting or film shooting is performed. Even if manual shooting of all frames for one line is performed, it is considered that proper exposure control has been performed, and appropriate exposure information (similar to the information to be used as the reference exposure amount printing) is recorded (the printer uses all the frames according to this information). It will be printed with the same predetermined exposure amount),
This is because the print according to the exposure state at the time of manual shooting is obtained by reflecting the user's intention of drawing without performing the correction by the auto print.

While the film is being fed by the film feeding unit 8, the magnetic recording unit 6 causes the recording information 31a to c ... n of each frame of the film 30 to be photographed information (not the Fft flag, other dates, etc.). The normal perforation recording information) is recorded, and the perforation detection unit 7 detects the perforation 32, thereby confirming the film winding and ending the photographing of the frame (S117). After that, the number of frames of the film 30 is incremented by 1 (S1
18) Then, the rewinding judgment is made depending on whether or not the number of frames exceeds the number of shootable images (S119). If it is not the last frame and rewinding is not performed, the process returns to S104, and if affirmative, the film feeding unit 8 is activated to start rewinding (S120).
The perforation detector 7 detects the perforations 32 on the film 30 to confirm the frame being rewound (S121), and decreases the number of frames by 1 (S12).
2) Continue until the number of frames reaches 0 (S12)
3). When the number of frames becomes 0, the proper exposure information of the Fft flag is recorded in the reader unit 31 at the end of the film 30 by the magnetic recording unit 6 (S124). Film feeding is continued until the film 30 is wound into a cartridge (not shown) (S125), and rewinding is stopped (S126).
The film 30 that has been photographed is taken out of the camera, and a series of sequences is finished (S127).

Thus, in this embodiment, the AE mode,
When the determination result of the reference exposure amount printing from the strobe mode or the like is all frames Fft = 1, the leader unit 31 of the film 30
Since Fft = 1 is recorded in the printer, it is not necessary to record each frame as in the conventional example, and the printer can read Fft = 1 and collect a single film to create a complete print by the standard exposure amount printing process. become. In addition, the recording area of each frame can be effectively used.

Next, a second embodiment of the present invention will be described. FIG. 4 is a flowchart of the information recording process of the camera according to the second embodiment of the present invention. The process of the second embodiment will be described with reference to FIG. The camera and film used are the same as in the first embodiment.

First, the loading of the film 30 is confirmed (S
201), automatic loading is performed by the film feeding unit 8, and the film 30 is driven to a predetermined position where shooting is possible and stopped (S202). The number of frames N is set to 1, and the NG counter, which is a criterion for recording information in the film reader unit 31, is set to 0 (S20).
3). One of the shooting modes is set by the shooting mode setting unit 10 (S204). Start photometric distance measurement SW1
When 15 is turned on (S205), distance measurement is performed by the distance measuring unit 3 and the result is converted into a lens drive amount, and AF is performed.
AF is performed by the control unit 4 (S206), and photometry is performed by the photometry unit 2 (S207). Exposure start SW2 16 is O
When it becomes N (S208), the exposure control circuit unit 5 controls the exposure to expose the film 30 (S20).
9).

The following steps S210 to S216 are the processing part for making the judgment of the NG counter. If the strobe is OFF (NO in S210), the AE mode and AE
Is NG (NO in S212 and NO in S213), the NG counter is incremented by 1 (S21).
6). Furthermore, if the strobe is ON (YES in S210
At S), when strobe auto and dimming NG (S21)
In the case of NO in 4 and NO in S215), the NG counter is incremented by 1 (S216). In all other cases, the NG counter remains unchanged. Further, the processing at the time of manual photographing is the same as in the previous embodiment.

While the film is being fed by the film feeding section 8, the magnetic recording section 6 causes the recording areas 31a to 31c of the frames to be recorded.
Normal shooting information such as the shooting date is recorded in n, the winding is confirmed by the detection of the perforation 32, and the shooting of the frame is finished (S217). After that, the number of frames N
Is incremented by 1 (S218), and it is determined whether or not rewinding is performed depending on whether or not the number of frames exceeds the number of shootable images (S219). The film feeding unit 8 is activated to start rewinding (S220). The perforation detector 7 detects the perforation 32 (S221), decrements the frame number N by 1 (S222), and continues until the frame number N = 0 (S223).

Then, the NG counter is judged and compared with a predetermined value K (S224). If the comparison result is less than K, it is determined that the number of inappropriate frames is small, and the flag FTF is set to 1 (S225). on the other hand,
If the comparison result is K or more, it is determined that there are many inappropriate frames, and the flag FTF is set to 0 (S226). Flag FTF
Accordingly, information recording is performed on the reader unit 31 of the film 30 (S227), the film feeding is continued until the film 30 is wound into the cartridge (S228), and the rewinding is stopped (S229). The film is taken out of the camera (S230), and a series of sequences is finished.

As described above, in the second embodiment, when the number of NG counters of the judgment result for each frame is compared with the predetermined value K and the number of inappropriate frames is small, the FTF for the reference exposure amount printing is read. Since the data is recorded in the section 31, the printer can read the FTF and process it in units of one film, and can make prints practically sufficient.

Next, a third embodiment of the present invention will be described. 5 and 6 are flowcharts of the information recording process of the camera according to the third embodiment of the present invention. The process of the third embodiment will be described with reference to FIGS. The applicable camera and film are the same as in the first embodiment.

First, the loading of the film 30 is confirmed (S
301), automatic loading is performed by the film feeding unit 8, and the film 30 is driven to a predetermined position where it can be photographed and stopped (S302). The number of frames N is set to 1, and the NG counter, which serves as a criterion for recording in the reader section 31 of the film 30 or in the recording areas 31a to 31c of each frame, is set to 0 (S303). The shooting mode setting unit 10 sets one of the shooting modes (S304). When SW1 is turned on (S30
5) Distance measurement is started by the distance measuring unit 3, the result is converted into a lens driving amount, and AF is performed by the AF control unit 4 (S30).
6). The photometry unit 2 performs photometry (S307), and SW2
When is turned on (S308), the exposure is controlled by the exposure control circuit 5 and the film is exposed (S309).

The subsequent processing of S310 to S316 is processing for judging the NG counter. When the strobe is OFF (NO in S310), the AE mode is set and the AE is set to N.
When G (NO in S311 and NO in S312)
Then, the NG counter is incremented by 1, and the flag FT (N) for each frame is set to 0 (S315). In this case, (N) represents the number of frames. Further, when the AE mode is manual (YES in S311), or when the AE mode is auto and AE OK (YES in S312), the flag FT (N) for each frame is set to 1 (S3).
16). If the strobe is ON (YES in S310)
At the time of S), it is strobe auto and dimming NG (S3
If NO in 13 and NO in S314), the NG counter is incremented by 1 and the flag FT (N) for each frame is incremented.
Is set to 0 (S315). Further, when the strobe is manual (YES in S313), or when strobe auto and dimming is OK (YES in S314), the flag FT (N) for each frame is set to 1 (S316). Normal shooting information for each frame is temporarily stored (S317), and the film is wound by the film feeding unit 8 and confirmed by perforation detection (S318). After that, the number of frames N is incremented by 1 (S319).

Next, moving to FIG. 6, it is determined whether or not rewinding is performed depending on whether or not the number of frames exceeds the number of photographable images (S320). The NG counter is judged and compared with a predetermined value K, and if less than K, the film 3
It is determined that the number of frames inappropriate for performing the reference exposure amount printing for all the frames of 0 is small (S321), and the flag FTF is set to 1 (S322). If K or more, it is determined that there are many unsuitable frames for performing the reference exposure amount printing, and the flag FTF is set to 0 (S322).

The film feeding unit 8 is activated to start rewinding (S324). The flag FTF is judged (S32
5) If FTF is 0, that is, if there are many inappropriate frames, the flag FT (N) for each frame in S315 and S316 is added to the normal shooting information D (N) stored in S317.
Is added (S326), and the magnetic storage unit 6 records the image information in the recording areas 31a to 31c of each frame (S32).
7). The perforation detection unit 7 detects the perforation 32 (S328), decrements the number of frames (S329), and continues until the number of frames becomes 0 (S330). When the number of frames reaches 0,
The flag FTF is recorded in the film reader unit 31.
In this case, if there are many inappropriate pieces, the flag FTF = 0, and if there are few incorrect pieces, the flag FTF = 1 (S3).
31). Then, the film feeding is continued until the film 30 is wound into the cartridge (S332), the rewinding is stopped (S333), the film is taken out from the camera, and the series of sequence is ended (S334).

As described above, in the third embodiment, the number of unsuitable frames is determined by comparing the number of NG counters and the predetermined value K from the flag FT (N) of the determination result for each frame and the NG counter, and it is unsuitable. When the number of frames is large, FT (N) is also recorded in the recording areas 31a to 31c for each frame together with the normal shooting information, and FTF = 0 (or 1) in that case is recorded in the reader unit 31. When the number of inappropriate frames is large, the printer can be instructed to process each frame.

Next, a fourth embodiment of the present invention will be described. FIG. 7 is a flowchart of the information recording process of the camera according to the fourth embodiment of the present invention. FIG. 8 is the fourth shown in FIG.

O, and NO in S415), set the NG counter to 1
Increment (S416). In all other cases, the NG counter remains unchanged.

While the film is being fed by the film feeding unit 8, the magnetic recording unit 6 records normal photographing information in the frame recording areas 31a to 31c of the film 30 and confirms the winding by the perforation 32 to confirm the frame. The shooting of is ended (S417). The number N of frames is incremented by 1 (S418), and it is determined whether or not rewinding is performed depending on whether or not the number of frames exceeds the number of shootable images (S419).
The film feeding unit 8 is activated to start rewinding the film 30 (S420). By detecting the perforation 32 (S421), the number of frames N is decreased by 1 (S42).
2) Continue until the number of frames N becomes 0 (S42).
3). When the number of frames becomes 0, the state of the recording method selection switch 13 is detected for the recording method of the reference exposure amount printing (S424). In the case of manual ON, the flag FTF is set to 1 (S425). Manual OF
In the case of F, FTF is set to 0 (S426).

In the case of automatic recording, the NG counter is judged and compared with a predetermined value K (S
427), if it is less than K, it is determined that there are few inappropriate pieces,
The flag FTF is set to 1 (S428). On the other hand, K
In the above cases, it is determined that there are many inappropriate pieces, and the flag FT is set.
F is set to 0 (S429). Recording is performed on the reader unit 31 of the film 30 according to the flag FTF (S430). Film feeding is continued until the film 30 is wound into the cartridge (S431), and rewinding is stopped (S43).
2). Remove the film from the camera (S433),
End the sequence.

As described above, in the fourth embodiment, the user operates the recording method selection switch 13 to select the reference exposure amount printing at his / her own will. Therefore, the user can automatically record in the first mode. Then, the record for designating the reference exposure amount printing can be freely selected manually.

As described above, in this embodiment, the reader unit 31
Information common to all frames to be recorded in (flags Fft, FTF),
Although the information (FT (N)) recorded for each frame is 1-bit information, the information may be increased in the number of bits. For example, if a camera that does not generate this information is also taken into account, (0,0) = non-instruction (1,0) = printer AE (1,1) = reference exposure amount printing It is also possible to determine whether or not it is desired.

Although the recording means is a magnetic recording system,
Of course, an optical recording method is also possible. However, since the magnetic recording method can process a large amount of information, the magnetic recording is more advantageous.

Further, in the present embodiment, the determination means for determining whether or not it is suitable for printing the reference exposure amount depends on the AE mode, the AE interlocking range, the strobe mode, and the dimming control. However, it is needless to say that the exposure correction is not limited to these,
It is also possible to make a determination by a film sensitivity shift state, a metering mode (whether spot metering or not), an automatic exposure shift function, and the like.

Correspondence between Embodiments and Embodiments In the above embodiment, first, the Fft flag is set to 1, and the Fft flag is judged from the strobe, manual, AE, and dimming states to be 0 and 1, Alternatively, first, the NG counter is set to 0, and the NG counter is judged from the states of strobe, manual, AE, and dimming, and the NG counter is incremented by 1, and the flag FT (N) of each frame is set to 0 or 1.
The determination process such as setting corresponds to the process of the determination means of the present invention. Further, when the operation state of the recording method selection switch 13 is detected and the manual ON is performed, the process of recording the flag FTF to 1 in the reader unit 31 of the film 30 is manually performed from the first mode of the automatic recording of the present invention. This corresponds to the switching process to the second mode.

[0061]

As described above, according to the camera of the present invention as defined in claim 1, when all the frames of one film film that has been photographed are exposed to the reference exposure amount,
Since the information is recorded in the information recording portion on the film, the printer does not need to read the information on the reference exposure amount printing for each frame, and the processing can be performed for each film, improving the processing capability of the printer. It is what makes me.

Further, in the camera of the present invention as defined in claim 2, when a predetermined number or more of the photographed films are exposed suitable for the reference exposure amount printing, the information recording portion on the film is recorded. Since the information is recorded, the printer does not need to read the information on the reference exposure amount printing for each frame when a large number of frames are suitable for the reference exposure amount printing, and the processing can be performed for each film. , To improve the processing capability of the printer.

Further, in the camera of the present invention as defined in claims 3 and 7, when a predetermined number of frames or more of the filmed film have been exposed suitable for the reference exposure amount printing, or the user desires. Since the information is recorded in the information recording section on the film when selected, the recording can be performed by the intention of the user.

Further, in the camera of the present invention as set forth in claim 4, when all of the filmed film or a predetermined number of frames or more are exposed suitable for the reference exposure amount printing,
Alternatively, when the user makes a desired selection, the information is recorded in the recording area of the reader section different from the recording area of each frame of the information recording section on the film. It is possible to eliminate the need for recording and effectively utilize the recording area.

Further, in the camera of the present invention as defined in claim 5, when a predetermined number or more of frames of the film photographed are exposed suitable for the reference exposure amount printing, the information recording portion of the film is recorded. Information is recorded in a recording area that is different from the recording area of each frame, and when the number of properly exposed frames is less than the specified number, information is recorded in the recording area of each frame on the film, so a large number of frames are used as reference exposures. When it is suitable for quantity printing, it is not necessary to record information for each frame and the processing capacity of the printer is improved, and when there are a few frames suitable for standard exposure amount printing, recording for each frame is also possible. It makes it possible.

Further, in the camera of the present invention as defined in claim 6, whether the exposure suitable for the reference exposure amount printing is performed depending on the AE mode, the AE interlocking range or outside, the strobe mode, the light control dimming state, and the like. Since it is determined whether or not the information is recorded, the information can be recorded based on the accurate determination.
