Abstract

PURPOSE:To print only the desired screens of an object with an optional distance by unifying a facsimile with a TV telephone. CONSTITUTION:A transmission part T amplifies 2 the voice signal supplied from a transmitter microphone 1 and supplies it to a transmission synthesizing part 5, and the picture signals sent from an image pickup part 3 are stored to a transmission buffer 4. A switch SW7 is set in a TV telephone mode when contacts A and C are closed and in a facsimile mode when contacts B and C are closed and changes the communication speed and the communication type in accordance with these modes. A control part 6 reads out the picture signal from the buffer 4 in response to the signal sent from the SW7 and synthesizes 5 it with a voice signal to send them to a telephone circuit 16 via a transmission/ reception separating circuit 15. The signal sent from the circuit 16 is applied to a signal analyzing part 12 of a reception part R via the circuit 15. The part 6 controls the part 12 for analysis of a facsimile signal and stores the picture signals to a reception buffer 11 to display them at a picture receiving part 9. Then a picture is printed 8 after an SW10 is closed. In a TV telephone mode, the picture given from the part 12 is displayed 9 and at the same time the voice signal is amplified 14 and sent to a telephone receiver 13.

Description

[Detailed description of the invention] This invention relates to an image communication device.

Conventional facsimile machines are generally limited to sending originals in the form of sheets, and cannot directly capture and transmit images of subjects at arbitrary distances. It had the disadvantage that it could not be transmitted. In addition, when receiving a call, the image from the other party is printed on recording paper, so even if an unnecessary image is generated due to an erroneous transmission, recording paper is consumed, so it is not economical if the system is set to receive calls automatically. It also had drawbacks. In the case of videophone calls, images are taken with a TV camera, so faces and landscapes can also be transmitted.ζ The receiving side typically uses a cathode ray tube display, so it does not consume recording paper, but it does not have a means of recording images. However, when receiving a document or the like, it has the disadvantage that it is not possible to save the image.

The present invention aims to eliminate the drawbacks of conventional facsimiles and videophones, and specifically aims to compensate for the drawbacks of both by integrating the facsimile and videophone.

In other words, it is possible to print videophone images on recording paper, to make it possible to send images of human faces, scenery, documents, etc. captured by the videophone camera to a general facsimile machine, and to make it possible to receive videophone images. The purpose of this system is to enable the department to receive printed matter from a general 7mm facsimile machine. The following description will be made based on all embodiments of the present invention.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, T surrounded by dotted lines is a transmitting section, and R is a receiving section, which serves as a transmitter and receiver.

In the transmitting section T, the audio signal from the transmitter 1 is amplified by the transmitting amplifying section 2 and input to the transmitting combining section 5 . On the other hand, the image is captured by the imaging section 3, and the image signal thereof is stored in the transmission buffer 4. This example is a television camera with three imaging units.

The switch 7 is a mode changeover switch, which allows the user to select between a facsimile mode and a videophone mode. Specifically, it has the function of switching between communication speed 1 communication blade type and all signal types. When contacts A and C close, the mode becomes videophone mode. When contacts F and O close, it becomes facsimile mode. When the communication partner connected to the telephone line 16 is switched to 7 is in facsimile mode,
By closing contacts B and Oi of the switch 7 of the device shown in the figure to set the facsimile mode F, the control section 6 controls the sending buffer 4.
The image data stored in the VC is read out from the VC so as to be output as a facsimile signal, and sent to the transmission synthesis section 5. -1: The control section 6 uses the transmission synthesis section 5 to synthesize the audio signal and the image 44 according to the state of the switch 7, and sends it to the transmission/reception separation circuit section 15, and then to the telephone line 16. If the communication partner is a device similar to the one shown in the figure, contact A of switch 7
, C are closed, that is, in the case of the videophone mode, the control section 6 controls the transmission buffer 4 and the transmission combining section 5 by closing the contacts A and 0 of the switch 7 in the figure. The signal is then sent to the entire signal transmission/reception separation section 15.

Next, the receiving section will be explained.

The signal coming in from the telephone line 6 is sent to the transmitting/receiving separation circuit section 15.
The signal enters the signal analysis section 12 through the. If the received signal is of the facsimile format, the control section 6 controls the signal analysis section 12 to analyze it as a facsimile signal and store the image data in the reception patcher 11. Then, it is displayed as an image on the image receiving section 9. Image receiving part 9 is V! , recorded on a cathode ray tube. When the closing switch 10 is closed, the image signal from the receiving printer 11 passes through the connector 17 and is printed at the printing section 8.

If the received signal is of the videophone system, the control unit 6 uses the signal analysis unit 12 to analyze it as a videophone signal, divide it into an image signal and an audio signal, send the image signal as image data to the reception buffer 11, and send the audio signal to the reception buffer 11. The signal is sent to the reception amplification section 1.
4', the signal is transmitted as sound from the receiver 13. The image data fl accumulated in the reception buffer 11 is sent to the image receiving section 9 and displayed. Print. The printing section 8 is not absolutely necessary, and if there is no need for recording, the printing section 8 may be cut out from the connector 17.

As explained above, the present invention provides videophone and fan/
In addition to the functions of the conventional 7A7mm and videophone, it also has the function of printing the image displayed on the image receiver in videophone mode, so it can be used to print documents, etc. It is convenient for saving images, and in the facsimile mode, previously only thin sheets could be sent, but with the present invention, images taken with a TV camera can be sent, making it easier to communicate with the subject. Since the distance can be set arbitrarily, it is possible to send images of three-dimensional objects such as faces and landscapes, and when receiving images, it is possible to display them once on the image receiving unit and print only the necessary images instead of printing them immediately. Therefore, it brings economical effects.
