[0002]

2. Description of the Related Art Conventionally, an intercom with a camera has an answering machine function of copying a visiting visitor and recording a message content in a VTR and reproducing the VTR after returning home to confirm the recorded content. The VTR has problems that it is large and heavy. Therefore, there is an increasing tendency to demand a compact and lightweight recording device. Also, there was no one that combined a telephone answering machine with a telephone intercom with a recording function. Therefore, the answering machine and the door phone with a camera had to be purchased separately, and the price was high. Upcoming
There is an increasing demand for the introduction of convenient functions at home, and a growing demand for a device that combines telephone answering machine recording and voice and video message recording by a camera and microphone.

Then, it is transmitted from the transmitting unit 3 to the other party. The other party informs him / her of his / her requirement such as "call me at 18:00". The contents of this message are received by the receiving unit 5.
The signal enters the second A / D conversion unit 18 via the, the signal is sampled, A / D converted, and recorded in the digital data recording unit 19. When the user wants to know the content of the message after returning home, the second D / A conversion unit 23 performs D / A conversion on the reproduced data in the digital data recording unit 19, and the converted data is converted into an analog signal via the filter. Then, the sound is amplified by the audio amplification unit 21, and the speaker 2
Output from 0.

When it is desired to convey a message to a family member, the input section 11 is operated to enter the message recording mode, and while standing in front of the second camera 13 and photographing himself / herself in the camera, the message content is input from the microphone section 17. The video signal input from the second camera 13 is sampled and A / D converted by the first A / D conversion unit 12, stored in the frame memory unit 24, and recorded in the digital data recording unit 19 as a still image. When the frame memory unit 24 receives the time signal from the timer 25, the first
The old data stored in the A / D conversion unit 12 is rewritten. On the other hand, the audio signal input from the microphone unit 17 is sampled and A / D converted by the first A / D conversion unit 12, and recorded in the digital data recording unit 19. When the family wants to know the message after returning home, if the digital data recording unit 19 is reproduced, the reproduced video data is 1D.
The A / A converter 8 performs D / A conversion, and converts it into an analog signal through the filter. Then, the image is amplified by the image amplifying unit 9, and the display unit 1
It is projected to 0. On the other hand, the reproduced audio data is the second D
The A / A converter 23 performs D / A conversion, and converts it into an analog signal via the filter. Then, the sound is amplified by the audio amplifier 21 and output from the speaker 20. The digital data recording unit 19
IC memory, DAT (digital audio tape)
And the like can be used. When you leave your house
The input unit 11 is operated to enter the absence mode. When there is a visitor, the first camera 14 photographs the visitor, is sampled by the first A / D converter 12 and A / D converted, stored in the frame memory unit 24, and stored as a still image in the digital data recording unit 19. Recorded in. If the frame memory unit 24 receives the time signal from the timer 25, the first A / D conversion unit 12
The old data that has been stored is rewritten. At the same time, the message contents of the visitor are input from the microphone unit 17, sampled and A / D converted by the first A / D conversion unit 12, and recorded in the digital data recording unit 19. When the family member wants to know the visitors and the contents of the message after returning home, if the digital data recording unit 19 is reproduced, the reproduced video data is D / A converted by the first D / A conversion unit 8 and converted into an analog signal via the filter. To do. Then, the image is amplified by the image amplification unit 9,
It is displayed on the display unit 10. On the other hand, the reproduced voice data is D / A converted by the second D / A converter 23 and converted into an analog signal via the filter. Then, the sound is amplified by the audio amplifier 21 and output from the speaker 20. When the family member is at home, the first camera 14 makes a copy of the visitor and displays it on the display unit 10 when the home mode is set from the input unit 11 and there is a visitor. On the other hand, a call with a visitor is performed via the intercom 16, the speaker 20, and the microphone unit 17. If a digital VTR is used instead of the digital data recording unit 19, a moving image can be stored instead of a still image.

[0009]

As described above, in the present invention, since the contents of the message are recorded in the digital data recording section (IC memory, DAT), the analog VTR of the recording medium as in the conventional case is recorded.
It can be made smaller and lighter, and when the IC memory is used, there is a great effect that handling is unnecessary.
