Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera, and more particularly to a so-called integrated video camera in which a recording section for a recording medium such as a video tape recorder (VTR) is integrated.

[0002]

2. Description of the Related Art In recent years, various types of integrated video cameras having VTRs have been developed. According to this integrated video camera, the video signal obtained by shooting is immediately recorded on the video tape, and shooting can be performed easily.

On the other hand, such a video camera is generally equipped with a microphone, and the sound picked up by this microphone is also recorded on a video tape at the same time.

[0004]

By the way, the microphone attached to the video camera only picks up the sound of the place where the picture is taken, and when recording other sound on the video tape, it is exclusively used after the picture is taken. The other editing device was used to insert another sound such as BGM by post-recording.

For this reason, it takes a lot of time and labor to insert other sounds (such as music) such as BGM into the image taken by the video camera.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a video camera capable of easily recording other audio together with video.

[0007]

According to the present invention, for example, as shown in FIG. 1, in a video camera for recording a video signal obtained by imaging in a predetermined recording medium 7, the video signal is recorded in the recording medium 7. At this time, the first audio signal obtained from the microphone 11 and the second audio signal obtained from the line input terminal 14 can be selectively recorded on the recording medium 7, and the first audio signal The second audio signal can be mixed and recorded on the recording medium 7.

In this case, the first voice signal and the second voice signal
The recording state on the recording medium 7 with the sound signal of is displayed in the viewfinder 8.

[0009]

By doing so, the audio signal obtained from the line input terminal can be satisfactorily recorded on the recording medium.

In this case, since the recording state is displayed in the viewfinder, it is possible to easily confirm the recording state of the voice when setting the mode or during photographing.

Then, each connection switch 15, 16, 1
8, 19 and the changeover switch 20 are controlled by the mode control circuit 32. The mode control circuit 32 is a circuit that sets various operation modes of the video camera in accordance with the operation of the mode setting key 33 of the video camera, and controls the above-mentioned switches according to the setting status such as the audio recording mode. .. Further, the information on the mode setting status in the mode control circuit 32 is supplied to the electronic viewfinder 8 to display the mode setting status. The display on the electronic viewfinder 8 is performed when the display mode is the menu screen display, and when the audio recording mode is set, the setting status of the audio recording mode is displayed on the menu screen. .. Figure 2
[Fig. 7] is a diagram showing a display example of the setting status of the voice recording mode.

The recording modes prepared by this video camera will now be described. First, two types of recording modes, a camera mode and a VTR mode, are prepared as image recording modes. In the camera mode, the image captured by the CCD imager 2 is recorded. A signal is recorded, and in the VTR mode, a video signal obtained from the outside is recorded in the line video input terminal 4a. In the VTR mode, the audio signal obtained at the line audio input terminal 14 is supplied to the audio processing circuit 31 side by the control shown in Table 1 described later, and is recorded together with the image obtained from the outside.

In the case of the camera mode, three types of voice recording modes are prepared. That is, a microphone voice recording mode, a line voice recording mode, and a mixed voice recording mode are prepared. These three types of voice recording modes are set by the mode control circuit 32 according to the operation of the key 33, and the connection of the connection switches 15, 16, 18, 19 and the changeover switch 20 are set according to the mode set by the mode control circuit 32. Control the switching of. Table 1 shows the control states of the switches in each of these modes.

[0023]

[Table 1]

By controlling the switches shown in Table 1, in the microphone voice recording mode, the voice signal supplied from the microphone 11 (or the connected external microphone) is supplied to the voice processing circuit 31 side for recording. To be done. Also, in line voice recording mode, instead of the voice picked up by the microphone,
The audio signal obtained at the line audio input terminal 14 is supplied to the audio processing circuit 31 side and recorded. The control state in this line voice recording mode is the same as that in the above-mentioned VTR mode. And in mixed audio recording mode,
The audio signal from the microphone and the audio signal from the line audio input terminal 14 are supplied to the variable resistor 17, and the variable resistor 1
Both audio signals are mixed at a ratio according to the adjustment state of the variable terminal 7 and the mixed audio signal is supplied to the audio processing circuit 31 side and recorded.

When the voice recording mode in this camera mode is set (switched) by operating the key 33, the mode control circuit 32 supplies information on the mode setting status to the electronic viewfinder 8 to display the electronic view. The menu screen shown in FIG. 2 is displayed on the finder 8. With the display of this menu screen, the operator (photographer) is notified of the selected mode among the three types of audio recording modes.

Further, in the video camera of this example, the mode control circuit 32 controls so that the microphone voice recording mode is always set at the initial setting (for example, when the video tape is replaced). Therefore, the line audio recording mode and the mixed audio recording mode are set to the key 33 before the start of shooting.
This mode is not set unless you operate.

In this way, while recording the image picked up in the camera mode, the audio recording state is
You can select from three types of modes: recording of the sound picked up by the microphone, recording of the sound that is supplied to the line input terminal from the outside, and mixed recording of both sounds. It becomes possible to record. For example, by connecting the line audio output terminal of the cassette tape reproducing apparatus in which the tape cassette in which favorite music is recorded in advance to the line audio input terminal 14 and setting the line audio recording mode, the microphone 11 Instead of the sound picked up by, the music reproduced from the cassette tape reproducing device is recorded. Further, in this case, by setting the mixed audio recording mode, both the audio picked up by the microphone and the music reproduced from the cassette tape reproducing device are recorded. In the case of this mixed audio recording mode, the variable resistor 17
The mixing ratio can be adjusted according to the adjustment state of, and the desired state can be adjusted.

By recording the voice other than the voice picked up by the microphone in this manner, it is not necessary to post-record the BGM or the like by using an editing device or the like later, and the time and labor required for editing can be saved. Further, in this example, the microphone voice recording mode is always set at the initial setting, so that voices from other than the microphone are not carelessly recorded, and other voices are erroneously recorded (or at all). Accidents are prevented.

Although the above-described embodiment is applied to the integrated video camera in which the VTR and the video camera are integrated, it is needless to say that the present invention is also applicable to the one in which the VTR and the video camera are separated. Further, although the present invention is applied to a video camera for recording on a video tape, it can also be applied to a camera for recording video and audio on another recording medium (for example, an electronic still camera for recording still images and audio on a magnetic disk).

Further, in the above-mentioned embodiment, the audio recording mode is displayed on the electronic viewfinder only by the menu screen, but the continuous recording mode may be displayed by superimposing during photographing. good.

[0031]

According to the present invention, the audio signal obtained from the line input terminal is recorded at the same time as the recording of the image being picked up, and it is possible to record the sound other than the sound picked up by the microphone.
It becomes easy to record BGM and the like.

Further, since the recording state of the voice is displayed on the viewfinder, the photographer can confirm the recording state of the voice only by looking at the viewfinder, and the wrong mode switching is performed, so that another voice is recorded. The accident in which is recorded is prevented.
