The state of the film rewinding motor 14 is shown.

At time t ₃ during the continuous recording operation of the video camera unit 5, the shutter button 19 is turned on, the recording operation is temporarily stopped, and the film 2 is wound up.
It is assumed that the film 2 is the end. At this time, when the stop switch is turned on at time t ₃₂ , the recording operation of the video camera unit 5 is stopped at time t ₃₃ , and film rewinding is started.

When film rewinding is performed and the recording switch is turned on at time t ₃₄ of the film rewinding period T ₁₀ ,
The recording operation of the video camera unit 5 is prohibited until the time t _{35 at} which the film rewinding is completed, and the recording operation is started from the time t ₃₅ . As described above, according to the present embodiment, in the video camera unit 5, when the still camera unit 3 captures images during the recording operation (intermittent recording operation) in the regular (fixed or variable) time period, the video camera Recording start / stop control is performed by the controller 30, and a signal indicating that movie shooting is being performed and a film winding prohibition command are sent from the video camera controller 30 to the still camera controller 21, and the still camera controller 21 In this signal receiving state, the shutter button 19
When the still picture is taken by opening and closing, the control command to the film winding 13 is suspended until the signal is released, and when the video camera unit 5 enters the recording standby state after the intermittent recording time has elapsed, The film winding prohibition command sent from the controller 30 to the still camera controller 21 is released, and a film winding command is transmitted to the film winding drive unit 13 to wind the film. Therefore, during the recording of the video camera, the film winding drive unit 1
In No. 3, since the film 2 is not wound, the film winding sound is not recorded as noise. Further, since the film winding time is shorter than the recording stop time in the intermittent recording, the film is not wound over the recording period of the intermittent recording and the film winding sound is not recorded.

By performing such an operation, it is possible to automatically perform still photography during the intermittent recording operation.
In the video camera unit 5, during continuous recording operation,
When the still camera unit 3 performs shooting, the still camera controller 21 sends a still shooting signal to the video camera controller 30 when the shutter 10 is opened and closed to open and close the still camera 10, and the video camera controller 30 causes the still camera controller 30 to operate. When the photographing signal is recognized, the recording is paused, the recording operation is suspended until the still photographing signal is canceled, and the recording state is automatically restored after the signal is canceled.

Therefore, during the recording of the video camera, the film winding drive unit 13 maintains the recording temporary standby state, so that the film winding sound is not recorded. Further, after the shutter 10 is opened and closed to perform still shooting, when the film 2 is completely shot and the film 2 needs to be replaced, the still camera controller 21 causes the video from the video camera controller 30. A drive command to the film rewinding drive unit 15 is prohibited by a signal indicating that shooting is being performed, and a control command is given to the film rewinding drive unit 15 by an instruction from the video camera controller 30 that video shooting has ended. Put out
Rewind the film. At this time, the still camera controller 21 sends a signal indicating that the film is being rewound to the video camera controller 30. With this signal, the video camera controller 30 prohibits the recording operation. It will not be done.

In the present embodiment, when still image shooting is performed during video shooting and film winding is performed, the recording operation of the video camera unit 5 is stopped and recording of the film winding sound is prohibited, but image recording is performed. There is also a method in which only the sound is muted while it remains. FIG. 6 shows an operation flowchart of the embodiment of the present invention in the case of prohibiting the recording of the sound of the video camera unit 5 at the time of film winding. The configuration of this embodiment is the same as that of FIG.
Since only the operation of the video camera controller 30 is different, the description of the configuration will be omitted.

When the shutter button 19 is turned on by the user, the still camera controller 21 issues a shutter drive instruction to the shutter drive section 11 to open the shutter 10 to expose the film 2, and the still camera section 3 displays a still image. Recording is performed (steps S1-2 and S2-2).
Next, the still camera controller 21 moves the video camera unit 5
The operating state of is determined (step S2-3).

When it is determined in step S2-3 that the video camera unit 5 is in the recording operation state, the signal processing unit 26 of the video camera unit 5 prohibits the audio signal from the microphone 25 from being supplied to the recording / reproducing unit 27, and the audio signal is reproduced. The signal is muted, and the film 2 is wound up (steps S2-4, S
2-5). Therefore, the winding sound of the film 2 is recorded via the microphone 25 of the video camera unit 5.

When the winding of the film 2 is completed in step S2-5, the muted state of the video camera unit 5 is released, and then the film detection unit 20 is referred to to determine whether or not the film 2 is the end. (Steps S2-6, S2
-7, S2-8). If the film 2 is not the terminal end in step S2-8, the rewinding of the film 2 is not necessary.
The process ends. Also, in step S2-8, the film 2
If it is the end, it is necessary to rewind the film 2. Therefore, the processing for rewinding the film 2 in steps S2-9 to S2-16, which is the same processing as steps S1-14 to S1-21 in FIG. To continue.

As described above, according to the first aspect of the present invention, the operation of the film drive unit for winding up and rewinding the film for recording a still image in the still camera unit and the operation of the image and sound by the video camera unit. By making the operation timing different from the recording operation, the film drive section operates while the image and sound are being recorded by the video camera section, and the operation sound of the film drive section is not generated without generating the operation sound. Since it is not recorded on the recording medium,
It has features such as preventing unwanted sound from being mixed in the recorded signal from the video camera.

According to the second aspect, when the still camera unit is operated during the recording operation of the video camera unit and the film drive unit is instructed to operate, the operation of the film drive unit is prohibited and the operation of the video camera unit is stopped. Since the film drive section operates after the recording operation is completed, the operation sound of the film drive section is not generated during recording by the video camera section. Therefore, the operation sound of the film drive section is recorded in the recording signal of the video camera section. In addition, by performing the above control when a long-time operation such as film rewinding is required, it is possible to prevent the video camera unit from recording a blank for a long time. .

According to the third aspect, when the film is wound after the recording by the still camera unit, the recording operation of the video camera unit is prohibited, so that the operation sound of the film driving unit is recorded by the video camera unit. It has the advantages that it is not recorded in the signal, and that the film is immediately rolled up after shooting with the still camera unit, enabling the next shooting.

According to the fourth aspect, the recording function of the video camera section is provided with a function of repeatedly recording at a constant cycle,
When recording with the above function, if the still camera section shoots during the recording, the film is wound during the period when the video camera stops the recording operation. The feature is that the sound of film winding operation is not recorded.

According to the fifth aspect, when the still camera is photographed during recording in the video camera section, audio recording in the video camera section is prohibited during film winding, so that the video camera section is prevented from recording. Noise such as film winding sound is not recorded, and recording of film winding sound is prevented by muting only the sound recorded by the video camera when film is wound for a short drive time. It is possible to prevent the interruption of the image, and since the film is rolled up even during the recording operation of the video camera section, it has the features that the still photography can be continuously performed.

According to the sixth aspect, since the film rewinding for a long driving time is performed at the end of the recording operation of the video camera section, there is a feature that the interruption of the voice can be minimized.
