  • Storing Facsimile Image Data (AREA)

Abstract

PURPOSE:To efficiently execute the reproduction of a picture having different picture size by temporarily storing received picture information and reading information stored along one side of the picture in a manner that the picture extends along the adjacent another side of the said one. CONSTITUTION:From one equipment, the original of A5-size is sequentially encoded along a direction A and transmitted. The other equipment receives the said encoded data and decodes it, and the picture data is temporarily stored in a picture data accumulating circuit 13 according to the storage address in the direction A. After the storing of one-page-share of the picture data ends, a vertical horizontal converting circuit 12 sequentially reads out the picture data in the circuit 13 in accordance with the storage address in a direction B, and supplies it to a recording circuit 11. As a result, the recording of A5-size is obtained, i.e. the said reception of an A5-size picture virtually means that a half of the A4-size original is received from a line. And, the interface with the line conforms to the CCITT requirement. Also, the data is encoded and transmitted efficiently.

The interface of a facsimile machine having a data compression means is determined based on the case of an A4 size machine recommended by the International Telegraph and Telephone Consultative Committee (hereinafter referred to as CCITT). Therefore, if the paper size is different from A4 size, each device must independently determine the number of dots in the main scanning direction for each paper size, or add a self-portrait signal to match the number of dots for A4 size. Methods such as doing this were used. That is, when a device that synthesizes A5 size reproduced images (hereinafter referred to as device 2) receives an A5 size original image from a device that handles A4 size original images (hereinafter referred to as device 1), first , the device 1 makes a call connection, and after the call connection is completed, the device 1 performs a calling procedure.

Thereafter, a CDCL signal is used to inform the device 1 that there are parameters for both A4 and A5 sizes. RDC from device 2
The LP signal informs that the parameters of device 2 are A5 size. Device 1 understands that Device 2 has an A5 size original, and furthermore, when an A5 size original is set,
It is determined that the 5-size original can be sent, and the procedure continues. Subsequently, information encoded using the CDUI signal is sent out. The number of dots per line in encoding specified by CCITT is 1728 dots as shown in FIG. The number of dots per line on an A5 size document is 118.
Since the number of dots is 4, device 1 adds 272 self-portrait signals to each side of the left and right sides, resulting in 17 dots for one line.
The image signal is encoded and transmitted using 28 donts. In the device 2, the received coded data is decoded by the decoding circuit 43, and then the image data from which white signals of 272 dots on the left and right sides are removed by the self-image signal removal circuit 42 is sent to the recording circuit 41 to generate a recording surface.
