The facsimile 2 of this example has a signal conversion section 11
By providing the information conversion unit 12 and
The NTSC signal can be converted into a normal facsimile read signal, and the image data from the video camera 1 can be automatically transmitted by facsimile.
That is, the light information that has entered the video camera 1 is converted into an NTSC signal by the video camera 1. Normally, the video camera 1 has an output pin, and image data (NTSC signal) is output from this output pin. The NTSC signal from the output pin is converted into image data of the scanning line by the signal conversion unit 11 and stored. For example, the signal conversion unit 1
1 receives the NTSC signal from the video camera 1,
A luminance signal is extracted from the NTSC signal, converted into a binarized signal in pixel units, and the binarized signal is stored in a one-screen configuration. The output from the video camera 1 is an interlace system, and here, two frames (first and second fields) are temporarily stored and the first and second fields are combined to form one screen. Configure and store. The stored scanning line image data of one screen configuration is converted into one page of normal facsimile data by the information conversion unit 12 and stored.

It is compressed and transmitted via modem 4 and NCU 3.

In this example, since the video camera 1 is always in the photographing state and the binarization and serial / parallel conversion of the video data are always performed in the facsimile, the user can operate the facsimile. , You can send this information at any time. Further, the facsimile 2 of this example is provided with a timer unit 7, a destination registration unit 8 and a polling control unit 9 which are well-known techniques, and can also perform reservation transmission or polling transmission for video data from the video camera 1.

In particular, between the facsimiles having the same functions as the facsimile 2 of this example, mutual polling control enables mutual transmission and reception of desired video information of the video cameras.

The details of the signal converter 11 will be described below with reference to FIG. FIG. 2 is a block diagram showing an embodiment of the configuration of the signal conversion unit in FIG. 1 according to the present invention. The signal converter 11 of this example is the NT from the video camera 1 of FIG.

A sync signal extraction circuit 21 for extracting a vertical sync signal and a horizontal sync signal from a signal, and a scanning line for counting the number of scan lines for one screen based on the vertical sync signal and the horizontal sync signal extracted by the sync signal extraction circuit 21. Counter 2
2, a compare circuit 23 for discriminating the vertical and horizontal coordinate positions of one screen from the video camera based on the count result of the scanning line counter and the count result of the horizontal coordinate counter 20, and the serial / parallel conversion circuit 17.
The video signal storage unit (NTSC in the figure, which stores the data converted in step S1) in a one-screen configuration (one raster consisting of the first field and the second field in this example) in association with the coordinate position determined by the compare circuit 23. VRAM for use) 24
And a scanning line synthesizing circuit 25 for synthesizing the data of each of the first field and the second field stored in the video signal storage unit 24 to generate image information for one raster, and the scanning line synthesizing circuit 25. The composite video signal storage unit (described as scanning line composition VRAM in the figure) 26 for storing the image information for one raster.

The NTSC composite signal input from the video camera is a signal as shown in FIG. 4, which is composed of a synchronizing signal and a luminance signal. In the case of color, a color signal is superimposed on the color signal, but a facsimile normally handles a monochrome image, and the color signal is not considered here. The signal converter 11 of this example uses the sync signal extraction circuit 21 to extract a vertical sync signal and a horizontal sync signal from the NTSC composite signal as shown in FIG. The vertical synchronizing signal and the horizontal synchronizing signal are the same as the vertical synchronizing pulse and the horizontal synchronizing pulse shown in FIG.
Further, the brightness signal extraction circuit 13 extracts the brightness signal. The scanning line of the video camera is as shown in FIG.
The scanning is sequentially performed to "1, 2, 3, ..., 263", and again to "263, 264, ..., 525". That is, one screen is displayed by scanning twice from the top to the bottom of the screen. The signal conversion unit 11 causes the scanning line counter 22 to count the number of scanning lines. In this example, the count is incremented by the vertical synchronizing signal and the horizontal synchronizing signal.

The clock counted up by the horizontal coordinate counter 20 is obtained by dividing the clock from the sampling clock generating circuit 18 into 1/16 by the frequency dividing circuit 19. Here, the horizontal synchronization frequency fH = 15.734 kHz
Is. Further, the line density at which the scanning line is read depends on how many clocks the sampling clock generating circuit 18 makes. Although the number of pixels in the main scanning direction of the facsimile varies depending on the reading density in the main scanning direction, if the number of pixels in the main scanning is Np, the sampling clock of the sampling clock generation circuit 18 is fH.
If xNp, finally, all the pixels in the main scanning direction of the facsimile can be sampled. The sampling clock generation circuit 18 can change the sampling frequency by software according to the size of the original to be transmitted. With this, it is possible to send an arbitrary document size.

The brightness signal extracted by the brightness signal extraction circuit 13 is binarized by the binarization circuit 14 according to this reference level when a reference level is set in the binarization reference level generation circuit 14 by software. . The binarized image data is serial / parallel converted by the serial / parallel conversion circuit 17 based on the sampling clock. The timing of this serial / parallel conversion depends on the data latch pulse from the compare circuit 23. The data latch pulse is an address arbitrarily set by the main control unit 10,
It occurs when the values of the scanning line counter 22 and the horizontal coordinate counter 20 match. This is because the main control unit 10
The data at the address that matches the data at the arbitrarily set address will be read. The main control unit 10 writes the read video data in the video signal storage unit 24. In this video data, the scanning line complies with NTSC and is skipped by one as shown in FIG. This is rearranged in the order of scanning lines by the scanning line synthesizing circuit 25, and as shown in FIG.
Memorize with. The video information of the video camera stored in the composite video signal storage unit 26 in this manner is converted into facsimile information by the information conversion unit 11 of FIG. Below, FIG.
The details of the information conversion unit 11 in FIG. 1 will be described with reference to FIG.

The information conversion unit 12 of this example stores an image conversion circuit 27 that converts the data of one screen configuration stored in the composite video signal storage unit 26 into one page of facsimile information, and the one page of facsimile information. A facsimile information storage unit (described as FAX VRAM in the drawing) 28. Since the sub-scanning line density of the data stored in the composite video signal storage unit 26 does not conform to a normal facsimile, the information conversion unit 12 causes the image conversion circuit 27 to interpolate / thinn sub-scanning, and Image processing associated therewith is performed and converted into data for facsimile. FIG. 8 shows the data status converted in this way and stored in the facsimile information storage unit 28. The data stored in the facsimile information storage unit 28 is subjected to image processing for normal facsimile information by the image processing circuit 6 in FIG. 1, and then transmitted through the code decoder 5, the modem 4 and the NCU 3.
