The following information is further displayed in the screen 51.

In the upper right portion of the screen 51, for example, the number 53 of film frames taken is displayed. This piece number 53
In the illustrated example, indicates that the 14th frame of the silver halide film 9 has a latent image having substantially the same image as the image obtained by removing the information display from FIG.

An exposure mode 54 of the photographic frame is displayed on the lower left of the screen 51, for example. This exposure mode 54
Is a known program mode ("P") in the illustrated example.
Is shown. Other examples of the exposure mode 54 include, for example, an aperture priority mode and a shutter speed priority mode.

Below the exposure mode 54 in the screen 51, the film drive mode 5 is a mode when the silver salt film 9 is driven by the film drive circuit 26.

In the illustrated example, the flash mode 56 indicates that the flash mode 56 is a known low-luminance automatic light emission mode (“AUTO”) in which the light emission amount, the light emission time, and the like are automatically set according to the subject brightness measured. Other examples of the flash mode 56 include a strobe off mode that prohibits strobe light emission, and a strobe forced light emission mode in which the strobe light is forcibly emitted regardless of the brightness of the subject.

Below the flash mode 56 in the screen 51, film information 57 specific to the silver salt film 9 loaded in the camera is displayed. In the illustrated example, the film information 57 indicates that the number of shootable images is 24, that is, the film is a film of 24 shots (“24EX”).
The film sensitivity is ISO100 ("ISO10
0 "). Another example of the film information 57 is to indicate whether the silver salt film 9 is a negative film or a positive film, for example.

At the lower part of the screen 51, for example, a shutter speed 58 of the shutter 8 when the currently displayed frame is photographed is displayed. This shutter speed 58 is

In addition, FIG.
This is an example in the case where all the information displays other than 1 are prohibited. This is because the imaging in the digital imaging mode is the exposure mode 54,
This is an example suitable for use in a simplified imaging system of a type that does not work with the film drive mode 55 and the flash mode 56.

Note that the camera operator may be allowed to set the permission or prohibition of each information display as desired.

Next, the operation of the camera configured as described above will be described.

FIG. 5 is a flow chart showing the main sequence executed by the camera.

When a battery or the like is loaded as a power source in the camera, the CPU 29 is initialized and execution of this main sequence is started.

Then, first, the power switch 39 of the camera
It is determined whether or not is turned on (step S
1).

When the power switch 39 is off, an instruction to turn off the display is given to the LCD monitor 34 (step S2), and then the first standby process is performed (step S3).

This first standby process is performed by the CPU 2
Before the operation of the CPU 9 is stopped, the condition setting for the CPU 29 to restart the operation after the stop is performed. Specifically, in the first standby process, the operation is set to start when the power switch 39 is turned on.

After the setting is made, the operation of the CPU 29 is stopped and the first standby state is entered. Further, when the power switch 39 is turned on to release the standby state by the first standby process, the process is restarted from the beginning of the "main sequence", that is, the step S1. .

On the other hand, in step S1, if the power switch 39 is turned on, the power-on processing for moving the taking lenses 1 and 3 from the retracted position to the wide position via the zoom / focus drive circuit 21. (Step S4), and then the main capacitor included in the flash circuit 36 is charged (step S4).
5).

Then, the timer built in the CPU 29 starts counting (step S6). This timer is a counter that counts up every predetermined time, and after clearing (resetting) the counter value to 0,
Start counting.

Then, it is determined whether or not the first release switch 37 is turned on by half-pressing the release button (step S7).

If it is determined that the first release switch 37 is on, then the area sensor 17 is operated.
The area sensor drive circuit 32 calculates a subject brightness value based on the image data photoelectrically converted by (1) to perform photometry (step S8). When the photometry is completed, the subject brightness value output from the area sensor drive circuit 32 is input to the CPU 29 via the signal processing circuit 33.

Next, the CPU 29 obtains the distance between the two images based on the signal input from the line sensor 7 of the focus detection device through the line sensor drive circuit 24, and thereby the photographing lenses 1 and 3 are set. Drive amount data for driving to the in-focus position is calculated. By transferring the calculated driving amount to the zoom / focus driving circuit 21 and driving a motor or the like, the photographing lenses 1 and 3 are moved in the optical axis direction to change the focus position (step S9). .

Based on the subject brightness value obtained by the photometry in step S8, the program diagram stored in advance in the CPU 29, and the sensitivity information of the silver salt film 9 detected by the film sensitivity detection circuit (not shown). hand,
A diaphragm value and a shutter speed that achieve proper exposure are calculated by a known technique (step S10). If the camera is set to the digital imaging mode, this calculation may be omitted.

In this way, when the preparation for photographing is completed, a subroutine "photographing sequence" as will be described later is provided.
Is called, and the area sensor 17 captures an image and the silver salt film 9 is exposed (step S11).
After the exposure, the process returns to step S5 to prepare for the next shooting.

On the other hand, if the first release switch 37 is off in step S7, it is determined whether or not the photographing mode setting switch 40 is on (step S12).

When the photographing mode setting switch 40 is turned on, it means that the silver salt digital photographing mode is set. Therefore, the silver salt digital photographing mode flag is set (step S13), If it is off, the silver salt digital photographing mode flag is reset (step S14).

Then, it is determined whether or not the power switch 39 of the camera is still on (step S15). If it is off, the process goes to the above step S2 to execute the first operation as described above. Perform standby processing, etc.

If the power switch 39 of the camera is still on, it is determined whether or not the timer has overflowed after the timer starts counting and a predetermined time elapses. Step S16).

If the timer has not overflowed, the process returns to step S7 and the above-described processing is repeatedly executed. On the other hand, if the timer has overflowed, a second standby processing described later is started. .

This timer processing is performed by
This is because when the operation switch such as the power switch is not operated even after the lapse of a predetermined time, the CPU 29 and the like are shifted to the standby state in order to reduce the power consumption.

That is, when it is determined that the timer has overflowed, the LCD monitor 34 is instructed to turn off the display (step S17), and then the second standby process is performed (step S18).

This second standby process is similar to the first standby process in step S3 as described above.
Before stopping the operation of the CPU 29,
Sets the conditions for starting the operation again.

More specifically, in the second standby processing, the switches 37, 38, 39, which interlock with the operation buttons,
When the state of 40 is changed, it is set to restart the operation of the CPU 29.

After the setting is made in this way, the CPU 2
The operation of 9 is stopped and the second standby state is entered. Further, when the second standby is released by changing the states of the switches 37, 38, 39, 40, the process is restarted from the step S5.

Next, FIG. 6 is a flowchart showing the subroutine "photographing sequence" in step S11.

When this process is started, first, a control signal is sent to the signal processing circuit 33 so as to turn off the LCD monitor 34 (step S21).

Then, it is checked whether or not the second release switch 38 is turned on by pressing the release button deeply (step S22).

If it is not turned on, it is checked whether or not the first release switch 37 is still turned on (step S23), and if it is turned on, the process returns to step S22. On the other hand, if it is off, this process is terminated and the process returns to the main sequence.

In step S22, the second
If it is determined that the release switch 38 is on, the aperture mechanism 2 is driven by the aperture drive circuit 22 to narrow down the aperture mechanism 2 to the set aperture value (step S24). The aperture value at this time is previously determined by a known technique based on the subject brightness, the film sensitivity, the program diagram, and the like, as described above, by the exposure calculation performed in step S10 of the main sequence shown in FIG. Has been done.

Next, the movable mirror 4 is retracted out of the photographing optical path by driving it through the mirror drive circuit 23 (step S25).

Then, it is judged whether or not the silver salt digital photographing mode flag is set (step S26),
If it is not set, the area sensor 17 captures an image (step S27).

On the other hand, when the silver salt digital photographing mode flag is set, similarly, after the area sensor 17 performs the photographing (step S28), the driving is further performed via the shutter driving circuit 25. The shutter 8 is controlled to the set shutter speed to be opened / closed (step S29). In this way, when the movable mirror 4 is raised and the shutter 8 is in the open state, a subject image is formed on the silver salt film 9 and exposure is performed.

Further, the shutter speed at this time is the same as the above-mentioned aperture value, by performing the exposure calculation in step S10 of the main sequence shown in FIG.
It has been decided in advance.

The above step S27 or step S29
Then, the signal processing circuit 33, which has received the capture permission signal from the CPU 29, causes the area sensor 17
The analog video signal is taken in from and converted into digital image data by known means (step S
30).

The digital image data is subjected to predetermined signal processing (for example, conversion into display data) in the signal processing circuit 33, and then transferred and stored in the DRAM 31 (step S31).

Thereafter, the movable mirror 4 retracted from the optical path by the "mirror up" routine at step S25 is returned to a predetermined position on the photographing optical path by performing this "mirror down" routine (step S).
32).

Furthermore, the aperture mechanism 2 which has been in the aperture state by the "aperture" routine in step S24 is returned to the open state by executing the "aperture reset" routine (step S33).

Then, the silver salt film 9 is wound up by one frame by driving it through the film driving circuit 26 (step S34). During this winding operation, the magnetic head 10 magnetically records predetermined data on the magnetic recording layer of the silver salt film 9 by a known technique.

Next, by instructing the signal processing circuit 33 to perform a display operation, the captured image is displayed on the LCD monitor 34 together with the shooting information, as will be described later in detail (step S35).

The digital image data stored in the DRAM 31 is compressed (step S3).
6) Then, after storing in the flash memory 30 (step S37), this photographing sequence is exited and the process returns to the main sequence.

FIG. 7 is a flow chart showing the subroutine "display on" in step S35.

When this process is started, it is first determined whether or not the silver salt digital photographing mode flag is set (step S41).

If it is determined that the silver salt digital photographing mode flag is not set, the information display data for the digital photographing mode as shown in FIG. 3 or 4 is set in the DRAM 31 ( Step S4
2).

On the other hand, when it is judged that the silver salt digital photographing mode flag is set, the information display data for the silver salt digital photographing mode as shown in FIG. 2 is set in the DRAM 31 (step S43). ).

Then, in step S31, DR
The electronic image already stored in the AM 31 and the DRAM 31 in the above step S42 or step S43.
The information display data stored in is read at a predetermined timing, and is combined by the image combining circuit 35 (step S44).

Then, the CPU 29 sends a control signal so as to turn on the LCD monitor 34, and the above step S
The image combined in 44 is displayed (step S45), and then the process returns to the subroutine "imaging sequence" shown in FIG.

According to such an embodiment, the photographing information regarding the silver salt photographing is displayed because it is displayed on the LCD monitor only when the image is photographed in the silver salt digital photographing mode. Just by looking at the image,
It is possible to easily discriminate whether the image is taken in the silver salt digital mode or taken in the digital imaging mode.

Further, when the information other than the date as shown in FIG. 4 is not displayed, it becomes possible to more clearly discriminate in which mode the image was taken.

Further, depending on the selected mode, if it is the silver salt digital photographing mode, exposure to the silver salt film and image pickup are performed at substantially the same timing, and if it is the digital image pickup mode. Can only take images.

The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications and applications can be made without departing from the spirit of the invention.
