Abstract

PURPOSE:To add information to a received picture or correct it to retransmit this picture without degradation of the picture quality, by storing a received facsimile picture in a storage device and provided a means which controls the change of contents of this storage device. CONSTITUTION:The facsimile signal received through a line TL is controlled by a controlling part 6 of a facsimile device 1 and is received and demodulated in a transmitting/receiving part 4 and is applied to a scanning reading and recording part 5 and is applied to a storage device 2 also. Information such as a signature is added to the picture recorded on a form 7; and when information is inputted to the scanning reading and recording part 5, read information is applied to a synthesizing device 3 and is compared with stored information of the storage device 2, and additional information is added to contents of the storage device 2. Consequently, the additional part is added to the received facsimile signal in the signal transmitted to the line TL, and the picture quality is not degraded because the received and outputted picture is not read again.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile image transfer system that prevents deterioration of image quality even if a received image is repeatedly transmitted.

In the general facsimile communication system, an image of a document is sent as a 71-kushiki signal from one facsimile device to the other 71-kushikiri device, and this facsimile message 4t is received and the image is recorded and output. It is something. In such a conventional 71 km communication system, there are cases where an image once received is subjected to additions or corrections and then retransmitted. For example, if you sign a received document for approval, send it to the next 71 facsimile devices, and repeat this sequentially among multiple facsimile devices, you can do this in the same way as when you do not sign/sign with your own WA machine. can do. In addition, there are cases where a document, etc. once received is added to or modified and sent back.

However, if the received and outputted image is repeatedly transmitted again by the facsimile apparatus, the quality deteriorates each time, and there is a drawback that it becomes impossible to print fine details.

The present invention improves the above-mentioned drawbacks, and eliminates the deterioration of the image quality even if the reception and retransmission of images is repeated, and also makes it possible to transmit any number of images by adding or modifying the received image. The purpose is to come out. Examples will be described in detail below.

FIG. 1 is a block diagram of an embodiment of the present invention, in which a facsimile signal 1 is provided with a storage device 2 and a synthesizer 5, and a 71-tV signal received via a line TL is sent to a facsimile device 10 control unit. The signal is received and demodulated by the transmitter/receiver section 4 under the control of the transmitter/receiver section 6, and is added to the scanning/reading/recording section 5 as well as to the storage device 2. The scanning/reading/recording section 5 records and outputs the facsimile signal on a paper 7, and the received facsimile signal is stored in the storage device 2.

After adding a signature etc. to paper 7, send it to facsimile machine 1.
When input to the 0-scanning and recording section 5, the read information is added to the synthesis device 5 and compared with the information stored in the storage device 2, and the additional information is written to the storage device 2 by the synthesis device 6. be included. That is, the difference between the received image stored in the storage device 2 and the transmitted image having the additional portion is detected, and the difference portion is synthesized into the received image.

Then, the contents of the storage device 2 are subjected to processing such as modulation in the transmitting/receiving section 4 and sent to the (b) line TL. Therefore, the transmitted facsimile No. 16 has an additional part added to the received facsimile signal, and since it is not a signal that has been received and output and then reread the good image, the other party's facsimile number 7 There is no possibility that the quality of the image received by the printing device will deteriorate.

Note that in order to compare the received image in the storage device 2 in the synthesis device 5 with the transmitted image obtained by inputting the paper 7, a synchronization mark etc. is added to the paper 7 at the time of reception and output, and the synchronization mark etc. is added to the paper 7 at the time of transmission. This can be done synchronously by reading. Further, additional parts such as sire etc. are added to a predetermined area of the paper 7, and read information t in that area is added.
- It is also possible to perform additional writing to the storage device 2. Further, when the received image and the transmitted image are synchronously compared as described above, the image recorded and output on the paper 7 can also be corrected and transmitted. In addition, when first transmitting (g), the information scanned and read by the scanning reading and recording section 5 is added to the transmitting/receiving section 4, and is transferred to the line TL without going through the storage device 2t.
A 77 km signal will be sent to the station. Such control is performed by giving instructions to the sti'J control section 6 by operating function buttons or the like.

FIG. 2 is a block diagram of another embodiment of the present invention. The same symbols as in FIG. 1 indicate the same parts, 8 is a CRT display device, 9 is a light beam;

It's a keyboard. The processing of the facsimile signal received via the line -TL' is the same as in the embodiment shown in FIG. 1, but the contents of the storage device 2 are added to the CRT display device 8 and displayed.

By adding or modifying this display content by operating the light pen 9 and keyboard 10, the content stored in the storage device 2 is added or modified. For example, by instructing the location to be added or modified using the light guide 9 and inputting the added or modified content from the keyboard 10], the content stored in the storage device 2 is updated under the control of the synthesizing device 3. In addition, if the keyboard 10 is configured to control the cursor of the CRT display device 8, the light bench 9t-
It can also be omitted.

When the addition and modification of the received image is completed and the start of transfer is instructed, the contents stored in the storage device 2 are sent from the hook-shielding device 1 to the line TL as a facsimile signal.

FIG. 5 shows a block diagram of still another embodiment of the present invention, in which a storage device 12 and a synthesis device 15Yt are provided on the switch 11 side, and a device 15 g + 156 + . . .
