Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of inputting document image information to a broadcasting device when performing circular facsimile communication.

[Prior art]

Broadcast communication is a communication method that transmits the same information sequentially or all at once to multiple destination terminals, but in order to achieve this in facsimile communication, a storage device is required to temporarily accumulate and store data. becomes. In order to effectively utilize the storage capacity of this storage device, a method □ in which data is subjected to redundancy reduction encoding, that is, compression encoding processing, is generally adopted. There are various methods for such encoding processing, but representative ones include one-dimensional compression encoding methods such as the modified Huffman method, and two-dimensional compression encoding methods such as the modified read method.

By the way, the above encoding methods generally include a video method that does not perform compression processing, a -dimensional compression encoding method,
The compression rate, that is, the transmission efficiency, improves in the order of two-dimensional compression encoding methods, but it cannot be said that the most suitable encoding method corresponds to the above order, considering communication conditions, image content of the transmitted document, etc. It disappears.

Conventionally, when performing circular facsimile communication, the operator has to reset the encoding method each time via the operation panel of the facsimile machine. I was trying to choose.

However, in this case, an operation by an operator is required each time the encoding method is changed, which poses a problem in that there are restrictions on the time period and environmental conditions for communication.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and in order to select the optimum encoding method and store it efficiently,
When writing image information for broadcast communication to the memory of the broadcast device,
It is an object of the present invention to provide an image information input method for broadcast communication that enables unattended broadcast communication by specifying an encoding method using a mark sheet.

[Structure of the invention]

Therefore, in the present invention, a mark sheet in which a mark for specifying an encoding method for encoding image information of a document is written and a document using the encoding method specified in the mark sheet are sequentially sent. By having the notification device read the information, the encoding method corresponding to each document is automatically set. This eliminates the need for an operator when writing into the memory of the image information relay device for broadcast communication, making unattended broadcast communication possible.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for inputting image information for broadcast communication according to the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows an example of a mark sheet used in the present invention.

In FIG. 1, the reference marks M1 to M5 are printed in advance in a filled state in order to detect the positions of the marked marks. In the column corresponding to the reference mark M1, three mark entry frames are printed to set the encoding method of the document, and the operator selects the desired encoding format by filling in any of the three mark entry frames. Specify.

If the mark entry frame VD is filled, it indicates that the image information will be transmitted as video information without encoding processing, and if the mark entry frame M) ( is filled, it means that encoding will be performed using the modified Huffman method. show,
When the mark entry frame MR is filled in, it indicates that encoding is performed using the modified read method.

In addition to the above, the mark sheet shown in FIG. 1 allows the communication mode, transmission speed, and destination code for broadcast communication to be specified. In other words, the communication mode (automatic sending/receiving-8R1 automatic receiving-R1 automatic sending-P) can be specified by filling in any mark entry frame in the column corresponding to the reference mark M2. You can specify the transmission speed (High Quality - FI, Standard - 8T, High Speed - FA) by filling in the mark entry frame in one of the corresponding columns, and then fill in the mark entry frame in the corresponding column by filling in the mark entry frame in the corresponding column. One relay partner station can be specified by filling it in to correspond to the preset destination code, and filling in the mark entry frame in the column corresponding to reference mark M5 to correspond to the preset destination code. This makes it possible to specify one destination station.

Note that the destination code is set in advance as a one-digit to several-digit code for each destination station, and the operator can specify multiple destination stations by filling in the mark entry frame corresponding to the code. I can do it. In this case, such a method was adopted in consideration of the area of the mark sheet, but a format may also be used in which multiple destination stations are directly specified by telephone number.

Next, a description will be given of a method of setting a document when the image information of the transmitted document is accumulated and stored in the circulation device using the mark sheet.

First, the operator sorts all transmitted documents by encoding method, taking into account various conditions such as communication conditions and document image content suspension. Then, a mark is written on the mark sheet to set the encoding method corresponding to the sorted transmission documents. After this, the mark sheets MS, , MS2, M
S3 and originals D1, D2, and D3 are set in sequence in the order shown in FIG. 2, and input into the memory of the broadcasting device in this order. For example, the mark sheet MS is set to be encoded using a video method, and the subsequent document is set after the mark sheet MS to be encoded using the video method. Next, mark sheet M
An encoding method using the modified Huffman method is set in S2, and the subsequent document D2 is set after the mark sheet MS2 to be encoded using the modified Huffman method. Next, the mark sheet MS3 is set to be encoded using the modified read method, and the subsequent document D3 is set after the mark sheet MS3 in order to be encoded using the modified read method. In this state, mark sheets and documents are cented one after another. After that, if you set the transmission time etc. of the broadcast communication appropriately, the reading operation of Marksee 1- will start at the transmission time.
The image information of the originals D1, D2, and D3 is input and stored in the memory of the circulation device based on the encoding process set in the mark sheet. Since the stored contents are transmitted to each designated destination of the mark sheet, an operator is not required, and unmanned broadcast communication using an optimal encoding method can be realized. Also, can you read the mark sheet in advance and memorize it on the broadcast device? ζ It is also possible to have a person perform the same operation as described above.

Although the communication device used in the present invention is not particularly shown in the drawings, when the present invention is realized, a general communication device with an accumulation memory function is configured to have a mark sheet reading function and an encoding method switching function. Then, the present invention can be easily realized.

In addition, in this embodiment, the encoding method is modified
Although the Huffman method and the modified read method have been adopted, other reliable encoding methods such as change point relative address encoding method may also be used as the encoding method can be switched based on the reading of the mark sheet. .

〔Effect of the invention〕

As explained above, according to the image information input method for broadcast communication according to the present invention, if the mark sheet for specifying the encoding method and the manuscript are placed in the transmission device at a time convenient for the operator, Since an operator is not required for subsequent accumulation storage processing and broadcast communication processing, unmanned broadcast communication using the optimum encoding method can be realized regardless of time of day or environmental conditions. In addition, it is also possible to use nighttime discount hours when telephone charges are low as communication time slots, making it possible to reduce costs.
