The audio signal processing circuit 18 converts the audio signal compressed on the time axis into an audio signal having the original length after the time axis expansion, and outputs the audio signal to the audio signal fade circuit 38 via the audio switch SWA.

The audio signal fade circuit 38 performs a fade-in process on the audio signal at the start of the reproduction, and then outputs the audio signal to the audio output terminal 40. Thereafter, the audio signal is subjected to a through output. At the end of the reproduction, the audio signal is subjected to a fade-out process and the output ends. The fade operation of the audio fade circuit 38 is controlled by a fade control signal Pf2 output from the MPU 30.

Next, how the still video player 51 is used will be described with reference to FIGS. 4 and 5. FIG. This embodiment is an example of a system in which audio such as narration and BGM is recorded on a video tape together with video captured by a still video camera from an external audio device.

The video output terminal 24 of the still video player 51
For example, a video input terminal of a video device 81 such as a VCR is connected, an audio output terminal 40 is connected to an audio input terminal of the video device 81, and an audio input terminal 46 is connected to an audio device such as a cassette deck or a CD player. Device 83
Output terminals are connected. The video output terminal and the audio output terminal of the video device 81 are connected to the video input terminal and the audio input terminal of a television 85 as a monitor device, respectively.

Next, the interval playback operation and the user's operation for dubbing at that time will be described with reference to the flowchart shown in FIG. Note that this process
The program is executed by the MPU 30 based on the program stored in the U30.

The user first selects a reproduction mode by the play mode switch 69 for interval reproduction and dubbing. Then, various settings relating to fade-in and interval reproduction are performed. That is, the fade mode changeover switch 61 selects the fade mode, the fade time changeover switch 63 selects the fade time, the timer set switch 77 selects the reproduction time per frame, and the down and up switches 70 and 71 reproduce the image. Select the start track, and then select the audio switch
By 79, the external input audio signal is switched to a fadeable state.

On the other hand, the MPU 30 enters this flowchart when the play mode changeover switch 69 selects the play mode. In response to the above switch operation, the recording / playback switch SW RF is switched to the FM demodulation circuit 14, the fade mode and the fade time are set, the playback time per frame is set, and the playback start track number is set. , Audio input terminal 4
2 to the audio signal fade circuit 38 (to the through side),
Select the fade mode, set the fade time,
A reproduction duration time per frame is set, and a reproduction start track number is set (S11 to S19). In this embodiment, the fade-in & out mode, the fade time is 1 second, the reproduction time of one frame is 10 seconds, the reproduction start track number is 1, and the external audio input / output is used.

Note that when the initial mode or the like is set in the MPU 30 and the user does not perform the setting operation, the MPU 30
Operate based on an initial mode and an initial value.

After the above settings, the user starts playback of the audio device 83, starts recording of the video device 85, and then turns on the interval playback switch 75 to start interval playback.

When the interval playback switch 75 is turned on, MPU3
0 starts reproduction of the video signal of the first track, outputs both fade-in control signals Pf1 and Pf2, and outputs the video fade circuit.
20 and the audio fade circuit 38 are operated for one second, and the fade-in processing of the audio signal and the fade-in processing of the video signal are executed in synchronization (S23, S25).

After the fade-in process, a so-called through state is established until the ten seconds set by the timer set switch 77 elapse or the stop switch 68 is pressed, and a normal reproduction operation is performed (S27, S35).

After the elapse of 10 seconds set by the timer set switch 77, the MPU 30 outputs only the fade-out signal Pf1 and causes only the video fade circuit 20 to perform a fade-out operation,
Only the video signal is faded out (S27, S29). Note that the audio fade circuit 38 is made to perform a through operation. That is, in the interval reproduction according to the present embodiment, the video signal is subjected to the fade processing for each frame, but the audio signal is subjected to the fade processing only at the beginning and the end. Needless to say, the audio signal may be configured to perform a fade process synchronized with the video signal for each frame.

Then, the MPU 30 moves the magnetic head 12 to the next track, causes the video signal processing circuit 16 and the like to start the reproduction process of the video signal recorded on that track, and outputs only the fade-in control signal Pf1 to output the video. Fade circuit 20
Perform a fade operation (S31, S33). And 10
Wait for the second to elapse (S27, S35).

By repeating the above operation, the frames are smoothly connected, and a visually natural image can be provided to the viewer.

The above operation is repeated until the last frame (S27 to S35). When the reproduction of the last frame is completed, the magnetic head 12 is returned to the first track, and the above processing is repeated.

When the stop switch 68 is pressed, the MPU 30 outputs both fade-out control signals Pf1 and Pf2 to cause the video fade circuit 20 and the audio fade circuit 38 to perform a one-second fade-out processing operation in synchronization, and terminate the reproduction processing. (S35 to S39). By this processing, the video and audio of the last frame disappear smoothly and visually naturally.

When the reproduction of the last track is completed, step 37
To end the interval reproduction.

When the interval reproduction is completed, the photographer stops the recording operation of 81 and stops the reproduction operation of the audio device 83. With the above operation, dubbing for synthesizing the video signal by the interval reproduction and the external audio signal is completed.

When the video tape produced by the above operation is reproduced, first, the video signal and the audio signal are faded in. When the reproduction of one frame is completed, the video is faded out. When the next frame is reproduced, the video is faded in. When the reproduction of the last frame is completed, the video and audio are faded out. Is done.

If interval playback is started by operating the interval playback switch 67 in a state where the fade-in or fade-out mode is selected, a fade process is performed at the time of starting or ending the playback of each frame according to the mode.

As described above, according to the still video player of the present embodiment, the video signal and the audio signal are faded in and faded out at the start of reproduction, at the end of reproduction, and at the time of switching the reproduction frame, so that a natural flow of video and audio can be achieved. Also,
You can easily use the fade effect when editing using an external device.

Although the embodiment in which the present invention is applied to a still video player has been described, the present invention can also be applied to a still video camera.

Also, if a memory means capable of storing at least one frame of video signal is provided and the stored video signal is repeatedly played back while being faded in / out, the seam of the video changes naturally even when dubbing by skipping frames. It is possible to obtain an easy-to-view image.

Next, more specific configurations of the video fade circuit, the audio fade circuit, and the fade control circuit will be described with reference to FIG. 6 to FIG. Members having the same functions as those of the embodiment shown in FIG. 1 are denoted by the same reference numerals.

The embodiment shown in FIG. 6 has a circuit configuration for simultaneously starting the video fade process and the audio fade process. In this embodiment, an electronic volume is used as an audio fade circuit.
101 is used. As the electronic volume 101, for example, an electronic volume model number "M51523AL" manufactured by Mitsubishi Electric Corporation can be used. As the video fade circuit 103, for example, a video encoder manufactured by Hitachi, Ltd.,
Model number "HA11776AMP" can be used.

An audio circuit 18 is connected to an audio signal input terminal of the electronic volume 101, and a video signal processing circuit 16 is connected to a video input terminal of the video fade circuit 103. The fade control terminal of the electronic volume 101 has a resistor R ₁
And is connected to the fade control port P1 of the MPU30 via the constant circuit (delay circuit) when a capacitor C _1, similarly to the fade control terminal for a video fade circuit 103, the time constant composed of the resistor R ₂ and capacitor C ₂ Fade control port P1 'of MPU30 via circuit
Is connected. Note that, inside the MPU 30, the port P1 'is connected via an inverter, and the port P1 is directly connected to the common terminal P. Therefore, port P1,
The level of P1 'is inverted.

The fade-in operation of the circuit configured as described
This is as shown in the timing chart of FIG. That is MP
U30 drops the terminal P to a low (GND) level before the start of reproduction. In this state, P2 is at a low level, P2 'is at a high level, and the electronic volume 101 and the video fade circuit 103 have the lowest gain, that is, are substantially in the off state. The audio signal and the video signal are hardly output from the video fade circuit 103.

When the MPU 30 inverts the level of the common terminal P to the high level, the levels of the ports P1 and P1 'change to high and low, respectively, so that the levels of the P2 and P2' gradually increase and decrease by the time constant circuit, respectively. Change to electronic volume 10
1 and the gain of the video fade circuit 103 gradually increase. That is, the levels of the output audio signal and the output video signal gradually increase, and fade in. That is, when the common terminal P is maintained at the high level,
The electronic volume 101 and the video fade circuit 103 enter a through state with the highest gain.

After the fade-in, the MPU 30 keeps the common terminal P at a high level. As a result, the electronic volume 101 and the video fade circuit 103 are kept in a constant high gain state, and are in a state similar to the normal reproduction.

Further, when fading out, the MPU 30 lowers the common terminal P to a low level. Then, the levels of P2 and P2 'are gradually changed by the time constant circuit, contrary to the above-mentioned fade-in, and the gains of the electronic volume 101 and the video fade circuit 103 are gradually lowered and faded out.

The P2 and P2 'signals in this embodiment correspond to the fade control signals Pf2 and Pf1 shown in FIG. 1, respectively. The time constants of the time constant circuits R1, C1 and R2C2 are arbitrary. That is, R1 · C1 = R2 · C2, or R1 · C1 ・ R2 · C2.

FIG. 8 shows a time constant circuit capable of switching the fade time (time constant) to three or four stages. That is, the resistance values of the resistors R ₁₁ , R ₁₂ and R ₁₃ are changed, and the switches SW ₁₁ and SW ₁₂ are changed.
By turning on / off both and turning on only one,
It will be appreciated that the fade time can be changed in four steps.

FIG. 9 shows a more specific circuit of an embodiment in which the fade time is program-controlled by the MPU 30. This circuit is built in the MPU 30. The MPU 30 outputs gradually increasing and decreasing serial data to the pair of fade data output circuits 110 and 111 at intervals corresponding to the fade time according to the fade mode. For example, when a video signal and an audio signal are to be faded in, the fade-in data is output to the pair of fade data output circuits 110 and 111, respectively, and when only the video signal is to be faded in, the fade-in data is output to one of the fade data output circuits 110. Is output.

The fade data output circuits 110 and 111 operate with a common clock output by the control unit of the MPU 30.

The fade data received by the fade data output circuits 110 and 111 are latched by a pair of 4-bit latch circuits 112 and 113, respectively. The latch operation of the latch circuits 112 and 113 is based on the fade data output circuit 11 receiving the fade data.
These are controlled by latch signals output from 0 and 111, respectively.

The 4-bit digital signals latched by the latch circuits 112 and 113 are converted into analog signals by a pair of D / A converters 114 and 115, respectively, and the analog signals are amplified by buffer operational amplifiers 116 and 117, respectively, and fade control is performed. The signals are output to the video fade circuit 20 and the audio fade circuit 38 as signals Pf ₁ and Pf ₂ , respectively. The video fade circuit 20 and the audio fade circuit 38 which have received the fade control signals Pf ₁ and Pf ₂ output a video signal and an audio signal with a gain according to the level.

As described above, during the fade-in processing, the level of the fade control signals Pf1 and Pf2 changes each time the fade-in data enters the fade data output circuits 110 and 111, and the video fade circuit 20 and the audio fade circuit 38 fade in. Execute the process. Conversely, during the fade-out processing, the level of the fade control signals Pf1 and Pf2 changes each time the fade-out data enters the fade data output circuits 110 and 111, and the video fade circuit 20 and the audio fade circuit
38 executes a fade-out process. As described above, the fade control means shown in FIG. 8 performs the fade processing of the video signal and the audio signal, only the video signal and the audio signal, for example, steps S25 and S29 of the embodiment shown in FIG.
It can be seen that the fade operations of S33 and S37 can be controlled.

As described above, according to the still video player of the present embodiment, the video signal and the audio signal are faded in and faded out at the start of reproduction, at the end of reproduction, and at the time of switching the reproduction frame, so that a natural flow of video and audio can be achieved. Also,
You can easily use the fade effect when editing using an external device.

Although the embodiment in which the present invention is applied to a still video player has been described, the present invention can also be applied to a still video camera.

Also, if a memory means capable of storing at least one frame of video signal is provided and the stored video signal is repeatedly played back while being faded in / out, the seam of the video changes naturally even when dubbing by skipping frames. It is possible to obtain an easy-to-view image.

Further, the timing of starting the fade of the video signal and the audio signal is arbitrary, and the fade processing may be performed by delaying one of them.

[Effects of the Invention] As described above, the still video device of the present invention can perform a fade process by synchronizing a video signal and an audio signal. Therefore, the still video device converts these signals to another recording medium, for example, a video signal. When recorded on tape, if there is only one frame, the video and audio related to that frame are played back as natural video and audio that appear smoothly and disappear smoothly, and multiple frames are recorded continuously at predetermined time intervals. In this case, the video and audio between frames are reproduced as natural video and audio that are smoothly connected.
