に送信する。In FIG. 1, calligraphy information is input from a calligraphy information input section 1 as a bit image expressed as "1" and "0", and is then stored in a calligraphy information storage section 2. The common part extraction control unit 3 extracts the calligraphy information of all pages from the calligraphy and drawing information storage unit 2, calculates the logical product between each page, extracts the common part across all pages, and stores it in the common part storage unit 4. do. On the other hand, the independent portion extraction unit 6 extracts calligraphy information page by page from the calligraphy information storage unit 2,
By calculating the exclusive OR of each page with the common part stored in the common part storage unit 4, an independent part is extracted for each page and stored in the independent part storage unit 7. The common portion and independent portion of the calligraphic information obtained in this way are encoded by encoding sections 5 and 8, respectively, and stored in encoded information storage section 9 according to a prescribed format. The communication control section 10 transmits the encoded document and image information stored in the encoded information storage section 9 to the receiver.

To simplify the explanation, let us assume that the input calligraphic information is three pages of data as shown in FIG. 2-1. The common portion extraction control unit 3 in FIG. 1 calculates the logical product of the three pages of data shown in FIG. 2-1, and obtains data for one page shown in FIG. 2-2. This becomes the common part of the calligraphy and drawing information. The independent partial extraction control unit 6 in FIG. 1 calculates the exclusive OR of the data shown in FIG. 2-2 and the data of each page shown in FIG. 2-1, and calculates the exclusive OR of the data shown in FIG. 2-2 and the data of each page shown in FIG. Obtain one page's worth of data. This becomes an independent part of each page of calligraphic information.
次に、第３図に書画情報の共通部分と独立部分を分割し

ジ識別子４ａを付加している。Next, FIG. 3 shows an example of a signal format when the common part and the independent part of calligraphy and drawing information are divided and transmitted. In order to distinguish the encoded information of the common part and the independent part, a common part identifier 1a and an independent part identifier 2a are added, and furthermore, in order to distinguish the encoded information of the independent part in each page, a page identifier 4a is added. There is.

することができる。Incidentally, on the receiving side, first, the calligraphy information of the common part is decoded from the received signal and stored in the storage section. Next, the calligraphy and drawing information can be reproduced by decoding the calligraphy and drawing information of independent parts of each page and respectively overwriting the calligraphy and drawing information of the common parts.

By having the means,
This has the effect of reducing the amount of information to be sent without limiting the fixed format used.
