DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the concept of the present invention will be described with reference to FIG. The release means 1 is an operation member such as a release button provided on the camera, and generates a release signal 11 by depressing the release button. At this time, the logical value of the release signal due to the depression is “1”.

The silver salt film 2 is made of an IX240 cartridge film or 135,6 × 7.6,6 × 6,6 × 4.5,
Various format films such as a 110 size film.

The film exposure means 3 comprises a photographic lens, an aperture, a shutter, etc.
Exposure. Exposure is started by a film exposure start signal 13.

The recording medium 5 is various recording media such as a floppy disk, a hard disk, a magneto-optical disk, and a memory. The electronic image recording means 6 includes a photographing lens, an aperture,
It comprises a shutter, an image sensor, an image A / D converter, a circuit for writing to a recording medium, and the like, and writes a subject image to the recording medium 5 as image data. Recording (writing) is started by an electronic image recording start signal 15.

The first detecting means 4 detects whether or not the silver halide film 2 can be exposed, and generates a detection signal 12. When the exposure is possible, the logical value "1" is generated. When it is impossible, a logical value "0" is generated. There are the following cases where the exposure to the silver halide film 2 is impossible.

(1) When no film cartridge containing the silver halide film 2 is loaded. (2) When the silver halide film 2 or the shutter is being driven (auto-load, winding, rewinding, shutter charging). (3) When a film cartridge in which the rewinding of the silver halide film 2 has been completed is loaded. (4) When the film cartridge is loaded without rewinding the silver halide film 2 photographed to the last frame. (5) When the film exposure means 3 and the film driving means do not operate due to a voltage drop or the like

The second detecting means 7 detects whether or not image data can be written to the recording medium 5 and generates a detection signal 14. When writing is possible, a logical value "1" is generated. When it is impossible, a logical value "0" is generated. There are the following cases where the writing to the recording medium 5 is impossible.

(1) When the recording medium 5 is not loaded. (2) When there is no space in the recording medium 5 for writing new image data. (3) The case where image data is being written to or read from the recording medium 5. (4) When the image sensor or the writing unit does not operate due to a voltage drop or the like.

The control means 8 comprises a logical product circuit 9 for starting film exposure and a logical product circuit 10 for starting electronic image recording. The AND circuit 9 comprises a release signal 11 and a detection signal 1
2 is a logical value “1”, that is, the silver halide film 2
When an exposure is possible and a release operation is performed, a film exposure start signal 13 is generated. The AND circuit 10
Means that when the release signal 11 and the detection signals 12 and 14 are both logical "1", that is, when the silver halide film 2 can be exposed and the recording medium 5 can be written, and when the release operation is performed. , An electronic image recording start signal 15 is generated.

The control means 8 has the following functions. (1) If the silver halide film 2 cannot be exposed, writing to the recording medium 5 is also prohibited. (2) When exposure to the silver halide film 2 is possible, the exposure to the silver halide film 2 is performed irrespective of whether or not writing on the recording medium 5 is possible. (3) The recording medium 5 capable of exposing the silver halide film 2 to light
Image data is written to the recording medium 5 only when writing to the storage medium 5 is possible.

In the first detecting means 4 described above,
Although the operation of the film exposure means 3 is prohibited when "the film cartridge is not loaded" is set to "exposure impossible", the user sometimes wants to confirm the operation of the shutter without the film cartridge.

FIG. 2B shows an improvement for fulfilling such a request, in which only the film exposure start signal 13 is generated when "the film cartridge is not loaded".

That is, the cartridge presence / absence detecting means 17
It detects whether or not a film cartridge is loaded. When no film cartridge is loaded, a detection signal 18 having a logical value “1” is output to the OR circuit 16. Therefore, when the film cartridge is not loaded, the output of the OR circuit 16 becomes a logical value “1”, and the release signal 11 causes the film exposure start signal 1
3 occurs.

Since the first detecting means 4 outputs the logical value "0" because "the film cartridge is not loaded", the output 15 of the logical product circuit 10 is output.
Becomes a logical value "0", and no electronic image recording start signal is generated.

Therefore, in the state without the film cartridge, the film exposure means 3 is operated by the release operation, but the electronic image recording means is not operated at six steps, and the operation of the shutter can be confirmed.

Next, the operation of the silver halide photographing and electronic photographing camera configured as described above will be described. FIG. 3 (B)
FIG. 2 is a general flowchart showing an entire processing process of a CPU 38 in FIG.

That is, first, the CPU 38 operates the release button 34
Is determined (step S1), and when the release button 34 is operated, a release process, which will be described in detail later, is performed (step S6), and the process returns to step S1.

When the release button 34 is not operated,
Next, it is determined whether or not the play button 35 has been operated (step S
2) When the playback button 35 is operated, a playback process is performed (step S7), and the process returns to step S1. As described above, the reproduction processing in step S7 reads out the image data stored in the recording memory 22 frame by frame,
This is a process of writing in the display memory 23, and the subject image captured before is displayed on the display unit 24 by this process.

If the play button 35 has not been operated, it is further determined whether the erase button 36 has been operated (step S3). If the erase button 36 has been operated, an erase process is performed (step S3). S8), and return to step S1. As described above, the erasing process in step S8 is a process of erasing the image data stored in the recording memory 22 and displayed by the reproducing process in step S7. It should be noted that all image data in the recording memory 22 may be erased when combined with another operation member or when the erase button 36 is pressed for a predetermined time or more.

When the erase button 36 is not operated, it is next determined whether or not the film cartridge 47 is loaded based on the output of the cartridge detecting means 25 (step S4). ,
An auto load process is performed (step S9), and the process returns to step S1.

If there is no film cartridge 47, it is determined whether the rewind button 37 has been operated (step S5). If the rewind button 37 has been operated, a rewind process is performed (step S10). The process returns to step S1.

When the rewind button 37 is not operated, the flow returns to step S1. Step S above
The release process in step 6 is performed as shown in the flowchart of FIG.

That is, first, the subject luminance output from the photometric element 28 is A / D converted to calculate the exposure level (step S21). Next, it is determined whether or not the film cartridge 47 is loaded based on the output of the cartridge detecting means 25 (step S22).
When the camera 7 is not loaded, the release processing ends.

On the other hand, the film cartridge 47
Is loaded, it is determined whether or not the film 48 is at the exposure position based on the output of the film detection means 26 (step S23). When the film 48 is not at the exposure position, the release process is terminated. Return to the upper routine. Therefore, when the film 48 is not at the exposure position, writing of image data to the recording memory 22 is not performed.

The state where the film 48 is not at the exposure position is that the film cartridge 4 after the rewinding is completed.
7 has not been taken out, or the film 48 taken up to the last frame has not been rewound.

When the film 48 is at the exposure position, it is determined whether there is room (free space) for writing new image data in the recording memory 22 (step S24).
If there is a free space, the subject image signal output from the image sensor 20 is A / D converted (step S).
25) After the image data obtained by the A / D conversion is written in the free space of the recording memory 22 (step S26), the process proceeds to step S28.

On the other hand, when it is determined in step S24 that there is no free space, the subject image signal output from the image sensor 20 is A / D converted in the same manner as in step S25 (step S27). However, in this case, the process proceeds to step S28 without writing the image data obtained by the A / D conversion into the recording memory 22.

At the time of the A / D conversion in steps S25 and S27, the exposure level, exposure time, and gain of the image sensor 20 may be adjusted based on the subject luminance data obtained in the photometry processing in step S21. good.

Next, step S25 or step S25 is executed.
The image data obtained by the A / D conversion in 27 is written in the display memory 23 (step S28). Therefore, when there is no free space in the recording memory 22, the image data is not written into the recording memory 22, but is simply written into the display memory 23. When there is free space, image data is written to both the recording memory 22 and the display memory 23.

When the writing to the memory is completed, the stepping motor 30 is driven to stop down the aperture 31 (step S29). Thereafter, the energization of the shutter magnet 32 is controlled to open and close the shutter 33. The time is controlled (step S30). In this case, the number of stops is determined based on the subject brightness data obtained in the photometry processing in step S21, and the opening / closing time of the shutter 33 is performed based on the subject brightness data obtained in the photometry processing in step S21. .

Then, after driving the stepping motor 30 to open the aperture 31 (step S31), the shutter is charged and the film 48 is wound up (step S32). Return. [Second Embodiment] Next, a second embodiment of the present invention will be described.

In this embodiment, the operation of the shutter can be confirmed without a film cartridge. The configuration for that is the same as that of the first embodiment, and the operation of the CPU 38 need only be changed as shown by the broken line in the flowchart of FIG.

That is, when it is determined in step S22 that the film cartridge 47 has not been loaded, the process proceeds to step S27 instead of terminating the release process.

In this manner, even when the film cartridge 47 is not loaded, the image pickup and the image display are performed, and the control of the aperture 31 and the shutter 33 is performed, so that the operation of the camera can be confirmed. it can.

Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the present invention. .

For example, in the above embodiment, the film taking lens 44, the photometric lens 48, and the image taking lens 4
Although the finder lens 45 and the finder lens 45 are separately provided, a single-lens reflex type finder optical system may be used to perform photometry, imaging, and finder observation using subject light transmitted through the photographing lens. .

The silver halide film may be another film such as a 135 format. Further, the aperture 31 and the shutter 33 are not separate ones, and a light blocking member such as a lens shutter which also serves as an aperture and a shutter may be used.

The recording medium is not limited to a nonvolatile memory but may be a medium such as a floppy disk, a hard disk, a magneto-optical disk, or a magneto-optical card. Further, the image display may not always be performed only when the release button 34 or the reproduction button 35 is operated, but may be such that the subject image is always displayed. Then, since the subject can be observed without looking through the viewfinder, the photographing posture can be made easy and the photographing can be performed from any direction.
