DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

[0007] FIG. 1 is a block diagram of a videophone device, which is roughly divided into an audio processing system and a video processing system, each of which is controlled and processed by a system controller 15.

Audio information, video information, and control information (dial numbers) input / output from the videophone device are connected to the ISDN line 1 via the communication interface 2 and transmitted.

In this communication interface, two information channels and one control signal channel are demultiplexed.

First, in the audio signal processing system, as shown in FIG. 1, the audio processing unit 16 to which the receiver 17 and the transmitter 18 are connected is controlled and processed by the system controller 15. At the time of reception, the digital voice information signal transmitted from the other side by the system control unit 15 in the information channel is supplied to the voice processing unit 16, and the D / A conversion processing is performed to form an analog voice signal. This voice signal is supplied to the handset 17. At the time of transmission, an analog voice signal is supplied from the transmitter 18 of the voice processing unit 16 and is subjected to processing such as A / D conversion to form a digital voice signal, and the communication interface 2 is controlled by the system control unit 15. Is transmitted to the other party as an information channel signal. Here, if there is a message or the like to be stored in advance, the information can be registered in the voice memory 19.

Reference numeral 21 is a call control, which is connected to the system control section 15 and uses a control signal channel to perform a call origination / reception processing for line connection.

The operation number from the operation unit 22 for inputting the dial number at the time of calling is the operation interface 23.
It is supplied to the system control unit 15 via the and processed.

Next, in the video signal processing system, as shown in FIG. 1, the image memory 6 to which the monitor 9, the camera 10 and the image processing unit 5 are connected is controlled by the system control unit 15 so that an image during transmission / reception is transmitted. Information can be temporarily stored. When receiving the image information, the received information is separated by the communication interface 2 and then input to the decoding circuit 3 to be composited from serial digital information to parallel digital information and further compressed by the image processing unit 5. After being expanded, the image data is temporarily stored in the image memory 6.

The image data stored in the image memory 6 is
To be output to the monitor 9, the D / A converter 7 converts the analog video signal, the video output section 8 adjusts the level, and the monitor 9 displays the image of the other party. When transmitting image information, the analog video signal received by the camera 10 is
The level is adjusted by the video input unit 11, converted into digital data by the A / D converter 12, and temporarily stored in the image memory through the input switching circuit. The image data stored in the image memory 6 is displayed on the monitor 9 via the D / A converter 7 and the video output unit 8 and is processed by the image processing unit 5 such as image compression to be processed by the encoding circuit 4. And encoded to form a digital image information signal.

This is supplied to the communication interface 2 as a signal of an information channel, multiplexed, and transmitted to the other party through the ISDN line 1.

At this time, if the user does not want to send an image due to the operator's convenience, for example, when changing clothes or putting on makeup, when waking up or feeling unwell, etc., the moving image file memory 14 is used instead of the image from the camera 10. The image information stored in advance and the voice information stored in the voice memory 19 are transmitted. When the operator operates the operation unit 22 to instruct to send a message, the system control unit 15 outputs a control signal to the moving image file memory 14 and the audio memory 19, and at the same time, the input switching circuits 13 and 20 are switched and the camera is switched. Instead of the 10 images, a moving image stored in advance and audio information are transmitted. Further, when the operator is out of the office, the system control is performed so that a message indicating that the operator is out of the office is transmitted to the other party as a moving image and voice information by setting the operation unit 22 in advance. It also has a function of controlling by the unit 15.

[0017]

As described above, according to the present invention, in addition to the image information by the built-in camera at the time of the transmission instruction, the image and the audio information before the transmission instruction can be transmitted. If you do not want to send an image due to the operator's convenience, such as when you are wearing makeup, wearing makeup, falling asleep, or feeling unwell, you can also send the previously stored image and voice information as a message while you are out. Therefore, there is an effect that the application as a videophone device is widened.
