In the continuous shooting mode when the release button 18 is pressed, first one track of the outer periphery is left empty (step 154), and then the video signal is recorded on the next track (step 155), and the release button 18 is pressed. If it is determined (step 156), and the release button 18 remains compressed, the process returns to step 155, and the next still image video signal is continuously recorded in the next track.

As a result, as shown in FIG. 7A, in the one-time shooting mode, the recording tracks V ₁₁ , V ₁₂ ,... Auxiliary tracks A ₁₁ , A ₁₂ ,. Are respectively installed. In the continuous shooting mode, as shown in Fig. 7B, an empty track A ₂₁ for audio is provided on the outer peripheral side, and recording tracks V ₂₁ , V ₂₂ , V ₂₃ ,... Is installed.

In Fig. 6, it is determined whether or not the post-editing recording switch 12 is pressed (step 157). If the post-editing recording switch 12 is pressed, a buzzer sounds for 0.4 seconds, and the start of recording is known (step 158). After releasing the editing recording switch 12 for 0.4 seconds (step 159), the recording time Tn is initially set to 0 (step 160). Then, recording is started 0.4 seconds after the post-editing recording switch 12 releases (step 161).

It is determined whether the post-edit recording switch 12 is pressed during recording (step 162), and if the post-edit recording switch 12 is not pressed during recording, it is determined whether the release button 18 is pressed halfway during recording. (Step 163). If the release button 18 is not pressed halfway during recording, it is determined whether the recording time Tn has elapsed 9.6 seconds (step 164).

When the recording time Tn elapses 9.6 seconds, a buzzer sounds (step 165), and it is known that the recording time has ended. Then, it is determined whether it is a single shooting mode or a continuous shooting mode (step 166). In the one-time shooting mode, the recorded audio signal is recorded on the empty track provided on the outer periphery of the recording track of the still image video signal (step 167). In the continuous shooting mode, the recorded audio signal is recorded on the empty track provided on the outer periphery of the recording track of the first still video signal during continuous shooting (step 168).

During recording, there is a failure in recording. In this case, the post-editing recording switch 12 is pressed during recording or the release button 18 is pressed halfway during recording.

In step 162, it is determined whether the post-editing recording switch 12 is pressed during recording. In step 163, it is determined whether the release button 18 has been pressed halfway. If the post-edit recording switch 12 is pressed during recording or the release button 18 is pressed halfway during recording, the one-time shooting mode is determined (step 169).

In the single shooting mode, the signal of the outer track relative to the recording track of the still picture video signal is erased (step 170).

In the continuous shooting mode, at the time of continuous shooting, the track signal of the outer circumference of the recording track of the first still video signal is erased (step 171).

During recording, there is a shutter chance. In this case, the release button 18 is fully pressed. When the release button 18 is fully pressed, still picture shooting takes priority over recording. Therefore, photographing can be performed without avoiding a shutter chance.

That is, in step 172, it is determined whether the release button 18 is fully pressed.

If the release button 18 is fully pressed, one track of the outer circumference is emptied for audio and a still video signal is recorded (step 173).

Simultaneous recording

The mode is set by the recording mode switching switch 11.

Simultaneous recording

In the mode, each time a still picture is taken by pressing the release switch 18, the video signal of the still picture is recorded on an annular track of the magnetic disk. At this time, an empty track is provided on the outer circumferential side of the recording track of the video signal. Along with this, when shooting of still images is performed, the audio signal is set to an inputable state. Then, the input audio signal is recorded in association with the captured still image. When the audio signal is input, the recording time is 9.6 seconds.

That is, in FIG. 8, it is determined whether the release button 18 has been pressed (step 201). When the release button 18 is pressed, one track of the outer circumference is emptied for audio and a video signal is recorded (step 202).

Then, a buzzer sounds for 0.4 seconds (step 203), and the rotation of the disk is stopped (step 204). Waiting 0.4 seconds (step 205), the recording time Tn is set to 0 (step 206).

As described above, the recording is started by waiting 0.4 seconds so that the recording of the disk can be performed because the rotation of the disk is completely stopped. If the disc is rotating at the time of recording, there is a possibility that noise generated by the disc rotation is introduced.

If the recording time Tn is set to 0, recording is performed (step 207).

It is determined whether or not the post-edit recording switch 12 is pressed during recording (step 208). If the post-edit recording switch 12 is not pressed during recording, it is determined whether the release button 18 is pressed halfway (step 209).

If the post-edit recording switch 12 and release button 18 are not pressed during recording, it is determined whether the recording time Tn has reached 9.6 seconds (step 210).

If the recording time Tn reaches 9.6 seconds, a buzzer sounds for 0.4 seconds (step 211), and the disk is rotated (step 212). Then, the input audio signal is recorded on the empty track on the outer side of the recording track of the still video signal (step 213).

During recording, there is a failure in recording. In this case, the post-editing recording switch 12 is pressed during recording, or the release button 18 is pressed halfway during recording.

In step 208, it is determined whether the post-editing recording switch 12 is pressed during recording. In step 209, it is determined whether the release button 18 is pressed halfway. If the post-edit recording switch 12 is pressed during recording or the release button 18 is pressed halfway during recording, the outer track signal of the recording track of the still picture video signal is erased (step 214).

There may be a shutter chance during recording. In this case, the release button 18 is fully pressed. When the release button 18 is fully pressed, still picture shooting takes priority over recording. That is, in step 215, if the release button 18 is fully pressed, one track of the outer periphery remains for audio, so that a still picture video signal is recorded (step 216).

In the playback, post-editing recording can be performed only during manual coma transmission. When the external microphone 83 is connected to the external microphone jack 4 and recording is performed using the external microphone 83, it is possible to perform recording while the screen is reproduced. When recording is performed by using the built-in microphone 3, the rotation of the disc is stopped at the time of recording, and the playback screen is muted. This prevents the sound of rotation of the disk from flowing in as noise when the built-in microphone 3 is used.

It is known that the buzzer will sound for 0.4 seconds when the post-editing recording switch 12 is pressed during manual coma transmission during playback (step 305), and recording is started.

If there is a playback sound at this time (step 306), it is immediately muted (step 307). Then, it is determined whether the external microphone 83 is connected to the external microphone jack 4 (step 308).

When the external microphone 83 is connected to the external microphone jack 4, recording is performed by this external microphone 83.

That is, when the external microphone 83 is connected to the external microphone jack 4, 0.4 seconds is waited (step 309), and the recording time Tn is set to 0 (step 310). Then, recording is performed by the external microphone 83 connected to the external microphone jack 4 (step 311).

It is determined whether the post-edit recording switch 12 is pressed during recording (step 312). If the post-edit recording switch 12 is not pressed during recording, it is determined whether the recording time Tn has elapsed 9.6 seconds (step 313). ).

If the recording time Tn has elapsed for 9.6 seconds, a buzzer sounds for 0.4 seconds (step 314), and the video is muted (step 315).

Then, it is determined whether there is an audio track corresponding to the video. If there is an audio track corresponding to the video, the recorded audio signal is recorded in the track corresponding to the video (step 317). If the audio signal has been recorded, the image is returned to the original image and the still image is reproduced (step 318).

If there is no ordering track corresponding to the video, it is determined whether there is an empty track on the outer periphery of the recording track of the video signal (step 319). If there is a blank track on the outer periphery of the video track, the audio signal recorded on the empty track on the outer periphery of the video track is recorded (step 320). When the audio signal is recorded, the process proceeds to step 318 where the image is reproduced and the still image is reproduced.

If it is determined in step 319 that there is no empty track on the outer periphery of the video track, the audio signal recorded on the empty track is recorded on the inner periphery of the video track (step 321). If the audio signal has been recorded, the process proceeds to step 318, where the image is reproduced and the still image is reproduced.

When it is determined in step 308 that the external microphone 83 is connected, recording is performed without stopping the rotation of the disc. Therefore, it is possible to record while watching the playback screen.

In step 308, when it is determined that the external microphone 83 is not connected, the video is muted immediately (step 322), and the rotation of the disc is stopped (step 323).

Then, 0.4 seconds wait (step 324), and the recording start time Tn is initially set (step 325). This 0.4 second corresponds to the time until the rotation of the disc is completely stopped.

The recording time Tn is initially set and recording starts (step 326).

It is determined whether the post-edit recording switch 12 is pressed during recording (step 327), and if the post-edit recording switch 12 is not pressed during recording, it is determined whether the recording time Tn has elapsed 9.6 seconds (step 328). .

If the recording time Tn has elapsed for 9.6 seconds, a buzzer sounds for 0.4 seconds (step 329), the rotation of the disc starts (step 330), and the flow advances to step 316.

As described above, when it is determined that the external microphone 83 is not connected at step 308, and recording is performed by the built-in microphone 3, the rotation of the disc is stopped at step 323 before recording, and the recording is finished. In step 330, the rotation of the disk is stopped. As a result, it is possible to prevent the mixing of noise caused by the disk rotation sound during recording.

Sometimes recording fails during recording. In this case, the post-editing recording switch 12 is pressed during recording. If it is determined in step 312 or step 327 that the post-editing recording switch 12 is pressed during recording, it is determined whether there is an audio track corresponding to the video (step 331). If there is an audio track corresponding to the video, the audio signal recorded in this audio track is erased (step 332).

According to the present invention, when the release button 18 is pressed completely, photography of still images is given priority over recording. For this reason, even if a shutter chance arrives during recording, shooting is performed without missing the shutter chance.
