Description of Embodiments Next, with reference to the accompanying drawings, a camera-integrated VTR according to the present invention
Also, an embodiment of the video camera will be described in detail.

FIG. 1 shows a functional block diagram of an embodiment of a camera-integrated VTR according to the present invention.

This device has a master lens 12, and behind the master lens 12, a CCD (charge coupled device) 14 for converting an optical image of an object captured by the master lens 12 from an optical signal to a video signal is arranged. . The video signal obtained by the CCD 14 is sent to the video signal processing circuit 16.

The video signal processing circuit 16 includes an amplifier that amplifies the signal from the CCD 14, and a means that performs gamma correction and white balance processing. The output from the video signal processing circuit 16 is input to the AD converter 18 and the recording unit 32. The AD converter 18 converts the input video signal into a digital signal. The output of the AD converter 18 is input to the video memory 20. Video memory 20
Temporarily stores the input video signal. Video memory
The output of 20 is input to the pattern recognition unit 22.

The pattern recognition unit 22 recognizes a pattern represented by the input video signal, for example, a barcode. Pattern recognition unit 22
Is sent to the data conversion unit 24. Data converter
In response to the signal from the pattern recognizing unit 22, 24 converts the signal representing the bar code into data indicating the address of the voice data stored in the music data memory 26.

The music data memory 26 stores various BGM data, and the data sent from the data conversion unit 24 is
For example, BGM data, that is, data of individual sounds constituting a song is read according to the song title data and sent to the BGM data memory 28. The BGM data memory 28 stores the BGM data read from the music data memory 26.

If the data input to the data conversion unit 24 is data representing individual sounds forming a song, the data output from the data conversion unit 24 is directly read without reading the data from the music data memory 26. It may be stored in the BGM data memory 28. Sound Generator 30 is BG
An audio signal is generated according to the data from the M data memory 28 and output to the recording unit 32.

The recording unit 32 performs processing for recording the video signal sent from the video signal processing circuit 16 and the audio signal sent from the sound generator 30 or the amplifier 34 on a video tape. That is, it includes FM modulation means for converting a video signal and an audio signal into a recording signal for recording on a magnetic tape.
The recording head 38 records the recording signal sent from the recording unit 32 on a magnetic tape.

The electronic viewfinder 42 displays the image picked up by the signal sent from the video signal processing circuit 16. The electronic viewfinder 42 also displays the characters generated from the character generator (CG) 44 in response to a signal from the control unit 40, and displays the operating state of the device to the operator.

The microphone 36 collects a sound generated from the subject and converts it into a sound signal, and is used when the sound generated from the subject is recorded at the same time when the subject is photographed. The amplifier 34 amplifies the audio signal output from the microphone 36 and outputs the amplified audio signal to the recording unit 32.

The control unit 40 is a control unit that controls each functional unit of the present device, and includes the CCD 14, the video signal processing circuit 16, the AD converter 18, the video memory 20, the pattern recognition unit 22, the data conversion unit 24, and the music data memory 26. , Control signals are output to the BGM data memory 28, the sound generator 30, and the recording unit 32, respectively.

Next, the operation and operation of this apparatus will be described using the flow shown in FIG. 2 and the images displayed on the electronic viewfinder 42 shown in FIGS. 3A to 3D.

The operator shoots a bar code indicating music to be used as background music with a video camera, confirms the bar code displayed on the electronic viewfinder 42 as shown in FIG. 3A, and then stores it in the operation unit 46. Press the switch (100). The image of the bar code enters from the master lens 12 and is picked up by the CCD 14, and the video signal processing circuit 16
Then, a predetermined process is performed and the image is displayed on the electronic viewfinder 42.

When the operator presses the memory switch, the control signal from the control unit 40 is sent to the character generator 44, the data generated from the character generator 44 is sent to the electronic viewfinder 42, and as shown in FIG. The word "Data is being converted" is displayed on the electronic viewfinder 42 (10
2).

When the operator presses the memory switch, the control signal from the control unit 40 is sent to the video memory 20, and the video signal processing circuit
The video signal displaying the barcode output from 16 is AD-converted by the AD converter 18, and then stored in the video memory 20 (104). The video signal of the bar code stored in the video memory 20 is sent to the pattern recognition section 22 and pattern recognition is performed (106).

The output from the pattern recognition unit 22 is sent to the data conversion unit 24, and data conversion is performed. That is, the pattern recognition unit
At 22, the barcode is pattern-recognized, and the recognized data is converted into, for example, data representing the music title of BGM (108).

In the above description, in order to specify the BGM data, the barcode is photographed by the camera and the pattern is recognized. However, instead of photographing the barcode, the beginning portion of the song as shown in FIG. 4 is changed. The musical score shown may be photographed by a camera to recognize the pattern. In this way, when the music score indicating the beginning portion of the music is photographed and the music is designated, the pattern recognition unit 22 recognizes the pattern, and the data conversion unit 24 recognizes each of the beginning portion of the BGM music. Converted to data representing notes.

In accordance with the data converted in the data conversion unit 24, for example, the data representing the song name, the data of the BGM song, that is, the data representing the individual notes of this song is read from the music data memory 26, and stored in the BGM data memory 28. It is stored (110). The data obtained in the data conversion unit 24 is B
Even in the case of data that represents individual notes at the beginning of the GM song, this data also enables the music data memory 26
The data of the music of BGM, that is, the data of all the notes constituting the music is read from and stored in the BGM data memory 28.

When the music data of the BGM is stored in the BGM data memory 28 in this way, the character "data conversion completed" is displayed on the electronic viewfinder 42 as shown in FIG. 3C (11
2).

The operator sees this display, knows that the BGM is ready, and starts photographing the subject. That is, the video camera is aimed at the subject and the shooting start button is pressed (114).
As a result, the shooting operation is started (116), and after the video signal captured by the CCD is processed by the video signal processing circuit 16,
It is sent to the recording unit 32. Further, the video signal is sent from the video signal processing circuit 16 to the electronic viewfinder 42, and a movie image to be shot is displayed as shown in FIG. 3D.

On the other hand, music data is read from the BGM data memory 28, a sound signal corresponding to these data is generated in the sound generator 30 (118), and sent to the recording unit 32. In the recording section 16, the video signal and the audio signal are subjected to FM modulation processing, sent to the recording head 38 and recorded on a magnetic tape. In this way, simultaneously with the recording of the video signal from the subject, that is, the recording of the movie image, the audio signal displayed by the barcode is recorded as BGM (120).

In this way, desired sound can be recorded at the same time when the movie image is recorded. When recording the sound sampled from the microphone 36 at the same time as the captured image, the operator operates the microphone on button of the operation unit 46 so that the sound signal from the subject sampled by the microphone 36 is amplified. The signal is amplified by 34, input to the recording unit 32, and recorded together with the image of the subject.

According to the present apparatus, as described above, desired sound can be recorded at the same time when the movie image is recorded. Moreover, since the sound is generated by the sound generator in this device, it is not necessary to prepare a device that generates sound such as a tape recorder for recording the sound, and only this device can record the sound in the movie. It can be done in conjunction with shooting. Therefore, since it is possible to perform shooting without generating sound, it is possible to perform shooting without affecting the surroundings by sound.

Further, the voice to be recorded is designated by photographing a barcode or a note with a camera, so that it is easy to designate. It should be noted that instead of using a bar code or a note in specifying a BGM voice, a character, a graphic, or the like displaying a music title may be photographed by a camera. Also, the sound recorded at the same time as the movie image is not limited to BGM, and, for example, a sound that describes the image to be shot, a sound effect, and various other sounds can be used.

Effects According to the present invention, it is possible to capture an image displaying audio data with an imaging device, generate audio data from the captured image, and record or output an audio signal at the same time when a subject is photographed. Therefore, voice recording can be performed without additionally preparing a device for generating voice. Further, since the voice to be recorded is designated by picking up an image by the image pickup means using a bar code, a musical note, etc., the designation is easy.
