On the other hand, an external video signal is supplied from the video input terminal VIN, A/D converted by the A/D converter 4, and stored in the memory 3 as an image. The stored image is transmitted from the facsimile machine 1.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a facsimile device that sends and receives images using a telephone line. Regarding the image communication device used.

0002

[Conventional technology]

Conventionally, images read by a scanner are converted into an appropriate format, A facsimile device that transmits and receives this information using a telephone line is known. This frame In a facsimile device, input and output of images is performed using paper as a medium.

0003 You can also use a modem to connect a personal computer to a host computer. accessed and wrote data to the host computer's hard disk drive. So-called personal computer communication is also known for reading data.

0004

[Problem that the idea aims to solve]

With conventional facsimile machines, data is input and output using paper as a medium. In addition to increasing paper consumption, if the paper stock on the receiving side runs out, data reception will be delayed. There were times when it became impossible to believe.

[0005] In addition, in PC communication, in order to use this, you must have a general user ID and password. It requires password registration and cannot be easily used by any user. In addition, in order to send and receive image images, the host side must increase the hard disk capacity. It is necessary to take measures such as

[0006] This invention reduces paper consumption and makes it easy to send images using telephone lines. An object of the present invention is to provide an image communication device that enables reception.

[0007]

[Means to solve the problem] The image communication device of the present invention is a communication device that transmits and receives image images using a telephone line. A facsimile device, a memory for storing images, and an input terminal for video signals. video signals supplied from the output terminal and the input terminal and received by the facsimile machine. The received image image is stored in memory, and the image image stored in memory is read. and a controller for controlling the output and supplying it to the output terminal and the facsimile machine. It is characterized by having

[0008]

[Effect]

According to the image communication device having the above configuration, the video signal supplied from the input terminal and the The transmitted image image is stored in memory. Image stored in memory In addition to being output as a video signal from the output terminal, it is also supplied to facsimile equipment. be done. That is, transmission and reception are performed using memory as a medium.

【Example】

Embodiments of the present invention will be described below with reference to the drawings.

[0009] FIG. 1 is a block diagram showing the configuration of an embodiment of an image communication device 100 of the present invention. The facsimile machine 1 is used for general facsimile transmission and reception. reception The resulting image is transferred to interface 2 (A/D converter and D/A converter). ) performs the necessary signal conversion and is stored in the memory 3. Memory 3 is It shall have a capacity that can store at least one screen worth of data. On the other hand, If there is an image already stored in Mori 3, this is the interface. 2, the signal is converted according to the communication mode of the facsimile device 1, and the facsimile It is supplied to the simili device 1.

0010 On the other hand, the video input terminal VIN is connected to the video camera 12, VTR 13, and handwritten input terminal. A video signal is provided from an external video device, such as a power pad 11 (see FIG. 2). The supplied video signal is decoded by the decoder 5 and digitalized by the A/D converter 4. converted into a digital signal. The video signal converted to a digital signal is stored as an image in memory 3. stored as an image. Also, the image stored in memory 3 is D/A converted. After being converted into an analog signal by converter 6, it is converted into a predetermined video output signal by encoder 7. The video signal is encoded into a video output terminal VOUT and output from the video output terminal VOUT.

[0011] In addition, the controller 8, which is made up of a CPU, etc., receives user operation commands (for example, Input the sending/receiving commands of the Kushimiri device 1, sampling frequency of A/D conversion, etc.) A control keypad 9 is connected. Memory of these images 3 writing and reading, control of A/D conversion and D/A conversion, and facsimile equipment. The transmission and reception control of the device 1 is all controlled by the controller 8 according to the user's operation commands. is being executed.

0012 Furthermore, a storage memory 10 for compressing and storing data is provided separately from the memory 3. This storage memory 10 increases data compression rate and storage capacity. This allows data for multiple screens to be stored.

[0013] Next, the transmission operation of the facsimile machine 1 will be explained first.

[0014] After the video signal supplied from the video input terminal VIN is demodulated by the decoder 5, It is converted into a digital signal by the A/D converter 4 and recorded as an image in the memory 3. be remembered. The image stored in the memory 3 is controlled by the controller 8. is read out and set to the communication mode of facsimile device 1 by interface 2. A corresponding signal conversion is performed. The facsimile machine 1 transmits this image (by telephone). (talk) is sent to the line. Of course the image to be sent is stored in the memory 3, so it is D/A converted by D/A converter 6 and then encoded by encoder 7. After encoding, output from the video output terminal VOUT at the same time, for example, They may be simultaneously monitored by the display device 14 (FIG. 2).

[0015] FIG. 2 is an example of connection of peripheral devices for transmission, and the image communication device 100 of FIG. A handwriting input pad 11, a video camera 12, and a VTR are used as video signal sources. 13 is connected, and a display device 14 is connected to the video output terminal.

[0016] Next, the receiving operation of the facsimile machine 1 will be explained.

[0017] The image received by the facsimile device 1 via the communication line is as described above. The signal conversion required to be stored in memory 3 by interface 2 as follows: is performed and stored in the memory 3 under the control of the controller 8. Recorded in memory 3 The stored image is D/A converted by a D/A converter 6 and output by an encoder 7. The video signal is converted from the video output terminal VOUT to match the video equipment used. output as a number. For example, external video equipment such as a television receiver may be used. A display device 14 can be used to display the received image. However, if necessary, it may be recorded using a recording device such as a VTR 13.

[0018] Figure 3 shows an example of connecting peripheral equipment for reception, with a display on the video output terminal. A ray device 14 and a VTR 13 are connected.

[0019] Note that the image to be stored in the memory 3 is stored under the control of the controller 8. be stored in the storage memory 10 as necessary, and sent and received by the facsimile machine 1. When transmitting, an arbitrary image may be selected and transmitted/received.

[0020] In addition, as in the conventional case, the facsimile device 1 uses paper as a medium to generate image images. You can also send and receive .

[0021]

[Effect of the idea]

As described above, according to the image communication device of the present invention, the transmission and reception of facsimile devices is possible. Equipped with a memory for storing image images, a video input terminal, and a video output terminal. This eliminates the need to send and receive faxes using paper as a medium, reducing paper consumption. This means that any user can easily send and receive images. You can expect a positive effect.
