Abstract

PURPOSE:To shorten the transmission time and to economize in recording paper in a receiving side by eliminating the data being unnecessary as information prior to transmission of data. CONSTITUTION:In a transmitting side, picture data of a document is read by a document reading par 1 and transferred to a memory 2. Subsequently, from facsimile data (picture signal) which has been accumulated in the memory 2, a page final line monitoring part 5 recognizes a final line address and sends it to a white line monitoring part 6. In this monitoring part 6, a line address in which other line than a white line is detected first toward the upper part of a page from the final line address is recognized, and sent out to a sending-out line deciding part 7. As a result, in the deciding part 7, it is decided to be all white extending from 'address' +1 which has been recognized by the monitoring part 6 to the end of the page, a final sending-out line address in which this data has been eliminating as unnecessary information is determined and sent to a sending-out address control part 8, and sending-out data in the memory 2 is controlled to the address which has been recognized by the deciding part 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile transmitter, and particularly to a system for recognizing and deleting unnecessary data as information in transmitted data.

[Conventional technology]

Conventionally, this type of facsimile transmitter encoded all data read by the document scanning section before transmitting it, and did not have a function to determine which data was unnecessary as information and a function to delete it. .

[Problem to be solved by the invention]

In the conventional facsimile transmitter described above, even data that is not necessary as information is transmitted, resulting in a long transmission time. Furthermore, there is a risk that extra recording paper will be used on the receiving side during recording.

[Means to solve the problem]

The facsimile transmitter of the present invention stores facsimile transmission data in the memory of its own terminal.

The final line address accumulated at this time is monitored.

Monitor the address where a line other than a white line appears for the first time toward the top of the page from this address. It has a mechanism to determine unnecessary data from the address information and delete that data from the transmitted data.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

On the sending side, a document reading section 1 reads the image data of the document and transfers it to the memory 2.

From the facsimile data (image signal) stored in the memory 2, the page final line monitoring section 5 recognizes the final line address and sends it to the white line monitoring section 6. The monitoring section 6 recognizes the line address at which a line other than a white line is first found toward the top of the page from the final line address, and sends it to the sending line determining section 7. The determining unit 7 determines that the end of the page is completely white based on the "address" + 1 recognized by the monitoring unit 6, and uses this data as unnecessary information to determine the final sending line address from which the completely white part is deleted. , to the sending address control unit 8, and controls the sending data in the memory 2 to the address recognized by the sending line determining unit 7.

The data then enters Codec 3 under pre-control,
It is sent out through modem 5.

〔Effect of the invention〕

As described above, the present invention can shorten the transmission time of deleted data by deleting unnecessary data as information prior to transmitting facsimile data. Furthermore, since this information is not received on the receiving side, there is an effect that recording paper can be saved.

Claims (1)

[Claims] a document reading section; a memory for temporarily storing the image signal output from the reading section; means for monitoring an address corresponding to the last line data of the page of the image signal; and means for monitoring the line address at which a line other than a white line first appears, means for determining the amount of data to be transmitted based on the address, and means for controlling the amount of data to be transmitted based on the determination information. facsimile transmitter.
