The eyepiece 57 of the finder eyepiece 5 is provided at the upper part of the back of the camera body 42, the release button 40 is provided at the grip, and the monitor 11 is provided at the center of the back.
Are provided with monitor screens 53 for displaying images. The screen 53 of the monitor 11 constitutes electronic image display means. Outside of this monitor screen 53,
A slide-type mode setting member 44 which is manually operated to selectively set one of a photographing mode and a display mode.
Is provided. By sliding between the EXP mark and the DISP mark, the mode switch 3 described above is provided.
Activate 2 Further, on the opposite side of the mode setting member 44 across the monitor screen 43 on the back, two push-type buttons of an up button 45 and a down button 46 for selecting and displaying an already stored image are provided. Are located. The up button 45 activates the display up switch 34, and the down button 46 activates the display down switch 35. Further, below the down button 46, an H type selection button 47 for operating the H switch 36 and the C

When the camera body 42 is pointed at the subject 41, the image of the subject 41 can be observed through the eyepiece 5 of the optical finder. Here, the mode setting member 4
When the setting of “4” on the “EXP” side is input to the control circuit 9, the exposure operation becomes possible. When the release button 40 is operated in this state, the subject 41 is exposed on the silver halide film 15. In synchronization with this exposure operation, the silver halide film 15
An electronic image substantially equivalent to the subject image that has been exposed is stored in the image memory 12. On the other hand, when the mode setting member 44 is set to the “DISP” side, the control circuit 9 causes the image stored in the image memory 12 to be reproduced. When the up button 45 or the down button 46 is operated with the mode setting member 44 set to the “DISP” side, an image other than the currently displayed image (the down button 46) is displayed.
Is operated, the previous image is displayed, and if the up button 45 is operated, the next image is displayed. At this time, if the P type or C type is selected at the time of shooting, a part of the screen is masked and displayed as shown as PM and CM in FIG. 5 accordingly. In this state, when one of the H type selection button 47, C type selection button 48, and P type selection button 49 is operated again to select a different screen size, the masking range is changed according to the new screen size.

Next, the operation of the camera configured as described above will be described with reference to the operation flowcharts of FIGS. FIG. 6 is a flowchart showing the main sequence.
In this flowchart, for simplicity, only the operation after the loading of the film cartridge is described. First, the open / close state of the back cover is detected by checking on / off of the back cover switch 31 in S1. When it is determined that the camera back cover is closed with the film cartridge loaded, the <empty feed> subroutine of S2 is executed to feed the film 15 to the first frame. Subsequently, in S3, the film information such as the film sensitivity and the number of photographed images is read from the information recording portion provided in the film cartridge.
Then, in S4, all the ratio registers are initialized with 0. This ratio register is a register for storing the screen size of each frame, and is prepared corresponding to each photographed frame.
Is operated, "0" is set when the C type selection button 48 is operated, and "2" is set when the P type selection button 49 is operated. Therefore, by putting "0" in all the ratio registers for all the number of photographed frames in S4, the H type print is selected in the initial state. Next, at step S5, "1" is entered into the frame number counter to initialize. Next, in S6, a value obtained by subtracting 1 from the contents of the frame number counter is set in the address register. This address register is a register for setting the address of the subject image stored in the image memory 12 in association with the photographed frame number.

Subsequently, the mode switch 32 linked to the mode setting member 44 is checked in S7. Here, if the mode setting member 44 is not set to the photographing mode (the EXP mark side), the display mode is shifted to by executing the <display> subroutine of S8. This display mode will be described later. On the other hand, if the shooting mode is set, the release switch 33 linked to the release button 40 is checked in S9. Mode setting member 4
If No. 4 is set to the shooting mode and the release button 40 is not operated, S7 → S9 → S10 is repeated while executing the subroutine of <display in F> in S10.

Here, the subroutine <display in F> will be described with reference to FIG. This subroutine is a subroutine for superimposing a screen frame corresponding to the selected screen size in the finder. In this subroutine, it is determined in S100 whether or not the P switch 38 for instructing P-type printing is ON, and if it is ON, "2" is stored in the ratio register corresponding to the current photographing frame in S101. And the process proceeds to S106. If it is not ON, it is determined in step S102 whether or not the C switch 37 for instructing the C type print is ON. If it is ON, the ratio register corresponding to the current photographed frame is stored in S103 in step S103. 1 ”, and S106
Proceed to. If it is not ON, it is determined in step S104 whether or not the H switch 36 for instructing H-type printing is ON. If it is ON, the ratio register corresponding to the current photographing frame is stored in S105 in step S105. 0 ”, and S10
Proceed to 6. If the H switch 36 is not ON,
The process proceeds to S106 without changing the contents of the ratio register. S1
In step 06, the contents of the ratio register are stored in the liquid crystal drive circuit 4 described above.
Transfer to 0. The liquid crystal drive circuit 40 that has received it selectively turns on the display elements 100 to 115 as described above, and superimposes the screen frame in the finder.

Returning to S9 in FIG. 6, when the release button 40 is operated and the release switch 33 is turned on, the program proceeds to S50.
The exposure operation is performed by the <exposure> subroutine.
In this exposure operation, the movable mirror 2 is raised, the sub-mirror 6 is lowered, the aperture operation is performed by the aperture member 13, then the shutter 14 is opened, and the operation of exposing the subject image on the silver halide film is performed. The details are well-known techniques, and a description thereof will be omitted. When the exposure operation is completed, S1
At 1, an image capture instruction signal is sent to the image processing circuit 10. Upon receiving this signal, the image processing circuit 10
The imaging device 8 converts the subject image on the image forming plane into analog image data and transfers the analog image data to the image processing circuit 10, which converts the image into digital image data and captures it. Next, after transferring the current contents of the address register to the image processing circuit 10 in S12, an image storage instruction signal is sent in S13. The image processing circuit 10 sets a memory area of the image memory 12 corresponding to the address data, and stores the image data in a designated area of the image memory 12 according to the image storage instruction signal. Therefore, the image data stored in the image memory 12 is stored in association with the number of photographed frames. As described above, since the operation of storing digital image data is performed in synchronization with the operation of exposing the silver halide film 15, the image optically recorded on the silver halide film 15 and the image stored in the image memory 12 are substantially equivalent. become.

Next, at step S14, an image display instruction signal is transferred to the image processing circuit 10, and then, at step S15, the content of the ratio register corresponding to the immediately preceding frame is transferred. Upon receiving this, the image processing circuit 10 displays the captured image data on the monitor 11 and performs a masking process on the display screen as shown in FIG. 5 according to the contents of the ratio register. This process is a process of superimposing and displaying a monochromatic (for example, white) mask (screen frame portion) on a subject image, and thereby enables a print job created in a development laboratory to be checked in advance. Next, in S16, it is determined whether or not the current frame is the last frame. In this method, the number of shots read from the information recording portion provided on the film cartridge is compared with the content of the current frame number counter, and if they match, it is determined that the last frame has been exposed. Is what you do. Here, when it is determined that the frame is not the last frame, the process proceeds to S17, and the <one frame winding> subroutine is executed.

Here, the subroutine <one frame winding> will be described with reference to FIG. First, in S201, a film feed motor (included in the film feed mechanism 23)
To rotate forward. Next, a <magnetic recording> subroutine is executed in S202. This <magnetic recording> subroutine
During the feeding operation of the film 15, the contents of the ratio register are sequentially recorded in the magnetic recording portion on the surface of the silver halide film from the least significant bit to the most significant bit one by one. Since various specific methods for magnetic recording have been conventionally proposed, detailed description thereof will be omitted. And
After waiting for winding of one frame in S203, the film feeding motor is stopped in S204, and the routine returns.

Returning to FIG. 6, when the winding of one frame is completed,
At 18, one is added to the frame number counter. Then, in S19, it is checked whether the rewind switch 41 is pressed. If the rewind switch 41 has not been pressed, S6 is performed again.
And the above processing is repeated. On the other hand, if it is determined in S16 that the last frame, the rewind switch 41 is determined in S20.
Is checked, and if the rewind switch 41 is not pressed, the mode switch 32 is checked in S21. If the rewind switch 41 is not turned on and the mode switch 32 is set to the photographing mode, steps S20 to S21 are repeated. On the other hand, if the mode switch 32 has been switched to the display mode,
Proceeding to S22, the <monitor display> subroutine is executed as in S8. On the other hand, if it is detected in S20 that the rewind switch 41 is pressed, a <rewind> subroutine is executed in S23. This subroutine is for film 1
In addition to the function of rewinding 5, the function of magnetically recording the contents of the above-described ratio register in the magnetic recording unit of each photographing frame during the rewinding operation is also included. The same rewinding operation is performed when it is determined in S19 that the rewind switch 41 has been pressed.

Here, the rewind operation in the <rewind> subroutine will be described with reference to FIG. This subroutine is executed when the rewind switch 41 is operated.
To be rewound into the cartridge. This subroutine also has a function of recording the contents of the above-mentioned ratio register in a magnetic recording unit corresponding to each photographing frame. First, in S301, a film feeding motor (not shown) included in the film feeding mechanism 23 is rotated in reverse to start rewinding. Next, the above-described <magnetic recording> subroutine is executed in S302. In the magnetic recording unit, the contents of the ratio register corresponding to each photographed frame have already been recorded in the <one frame winding> subroutine described above, but the photographer has changed the print size after that. Therefore, it is necessary to perform magnetic recording even in the rewinding operation. still,
In the magnetic recording at the time of rewinding, re-recording may be performed only for the photographed frame whose setting has been changed. Since this recording operation is completed in a shorter time than the rewinding of the silver halide film by one frame, the return from the <magnetic recording> subroutine is followed by the rewinding of one frame in S303. Wait for. When rewinding of one frame is completed, "1" is subtracted from the frame number counter in S304, and it is checked in S305 whether the frame number counter has become "0". If the frame number counter has not yet reached "0", the flow returns to S302 again to record the number data of the next frame. On the other hand, when the frame number counter becomes "0", it is determined that rewinding has been completed, and after waiting for a predetermined time in S306, S30
At 7, the film feed motor is stopped and the routine returns.

Returning to FIG. 6, when the rewind operation is completed, S
At 24, the process waits until the back cover switch 31 is opened. When the back cover switch 31 is opened (that is, when the film cartridge is removed), all the image data in the image memory 12 is erased at S25, and then to S26. To set the number of frames to 0 to clear the contents. The reason why all the digital image data stored in the image memory 12 is deleted is that the digital image data stored in the image memory 12 corresponds to the image optically recorded on the silver halide film 15. Therefore, when the film cartridge is taken out, there is no need to store the image data thereafter, and if left as it is, the photographer may be confused when performing a shooting operation with a new film cartridge. There is danger.

Next, the <monitor display> subroutine of FIG. 10 will be described. First, in S401, it is checked whether the content of the address register is 0 or not. If the content of the address register is 0 at this point, the image has not been shot yet, and the image data to be displayed is not stored in the image memory 12, so the process returns. On the other hand, if the content of the address register is not 1, that is, if at least one image data is stored, the contents of the address register, the image reading instruction signal, and the ratio corresponding to the address register are passed from S402 to S405. The contents of the register and the display instruction signal are transferred to the image processing circuit 10 in this order. The image processing circuit 10 sets a memory area of the image memory 12 corresponding to the address data,
The image data is read from the storage area set according to the image reading instruction signal, and the read image data is masked and displayed on the monitor 11 according to the image display instruction signal.

Next, in S406, it is determined whether or not the P switch 38 for instructing P-type printing is ON. If the P switch 38 is ON, the ratio register corresponding to the current photographed frame is stored in S407 in "S407". "2" is entered, and the flow proceeds to S412.
If it is not ON, it is determined in step S408 whether or not the C switch 37 for instructing C type printing is ON. If it is ON, the ratio register corresponding to the current photographed frame is stored in S409 in step S409. 1 ", and the process proceeds to S412. If it is not ON, it is determined in step S410 whether the H switch 36 for instructing H-type printing is ON, and if it is ON, the ratio register corresponding to the current shooting frame is stored in S411 in step S411. "0" is entered and the process proceeds to S412. If the H switch 36 is not ON, the process proceeds to S412 without changing the content of the ratio register. Next, S4
Display down switch 3 linked to down button 46 at 12
4, the state of the display up switch 33 linked to the up button 45 in S416 and the state of the mode setting switch 31 linked to the mode setting member 44 are checked in S420. In this series of checks, if both the display down switch 34 and the display up switch 33 are not ON and the mode setting switch 31 is not set to the photographing mode, SS412 and subsequent steps are repeated. On the other hand, if it is determined in S420 that the mode setting switch 31 has been returned to the shooting mode, the process returns.

As described above, the display up switch 34 and the display down switch 35 are switches for displaying an image other than the currently displayed image, and if the down switch 35 is on, the previous image is displayed. If the up switch 34 is ON, the next image can be selected. S41
If it is determined in step 2 that the display down switch 35 is ON, then it is checked in step S413 whether the contents of the address register are 1. If the content of the address register is not 1 at this time, the content of the address register is decremented by 1 in S414, and after waiting for a predetermined time in S415 to prevent a malfunction due to chattering, the process proceeds to S40.
2, the selected image is displayed. On the other hand, if the content of the address register is 1, it means that the first shot image data has already been displayed, and it is not possible to go back to an earlier image. Therefore, the process returns to S406 without performing any processing. Also, S41
If it is determined in step 6 that the display up switch 34 is ON, then the contents of the address register and the contents of the frame number counter are compared in step S417, and if the contents of the address register and the contents of the frame number counter are not equal, In step S418, the content of the address register is incremented by one. In step S419, the process returns to step S402 after waiting for a predetermined time to prevent a malfunction due to chattering, and displays the selected image. On the other hand, if the contents of the address register and the contents of the frame number counter are equal in S417, the operation of the display up switch 34 is ignored since the currently displayed image is the latest frame, and the process returns to S406.

By adopting such a configuration, the user can visually and clearly determine whether the image is to be printed in the H type, the C type, or the P type, and what the screen configuration will be at that time. It can be confirmed on the display means. In the first embodiment, the image displayed on the monitor device is subjected to a single-color masking process in accordance with the set screen size. If displayed, comparison with the whole image can be made, so that it is easier to use. In the first embodiment, the monitor display operation is performed after the end of the exposure operation. However, a series of monitor display operations is repeated before the exposure operation (before the release button is operated). For example, it is possible to prevent wasteful exposure of the film to a screen size that is not desired.

Next, a second embodiment of the present invention will be described. In the second embodiment, print density is recorded as print reference information. In the second embodiment, instead of the three operation buttons (H type selection button 47, C type selection button 48, and P type selection button 49) provided in the first embodiment, a print is performed. A monitor screen is provided by providing two buttons (lightness button and darkness button) for changing the density by a predetermined amount, and operating one of the two buttons while viewing the image selected in the display mode. The density of the upper image changes, and at the same time, the adjustment amount is recorded at the time of rewinding in the magnetic recording unit corresponding to each photographing frame. In the viewfinder, a “+” mark or “−” mark is displayed every time the above operation is performed.
It is supposed to be imposed. With this configuration, the user can check an image corresponding to the exposure ± correction on the monitor screen. As described above, various types of print reference information can be considered in addition to the trimming information and density information, and the present invention can be applied to these various types of information.
