Abstract

PURPOSE:To send a larger drawing in a short time through the use of a line by splitting a picture data into plural pages electrically, adding information corresponding to the original picture and sending the data through compression. CONSTITUTION:A scanner section 12 reads a picture data and a picture data processing section 15 expands one page of data split into a size to be able to sent into a larger picture image. Moreover, the picture data processing section 15 adds information to make correspondence with the position of original picture to the blank. Thus, a picture data compression/expansion section 16 compresses the picture data, transfers the resulting data to a picture data transmission section 17 and sends the picture data to the line. Other data is processed similarly and one data is split into 8 pages and the resulting picture data is sent. Thus, a drawing with a size larger than the size able to be sent is sent and received in a short time and additional information is discriminated to receive the data with a conventional picture transmitter.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an image data transmitting device used in optical file systems, personal computers, office automation systems, and the like.

2. Description of the Related Art Conventionally, image data transmitting apparatuses of this type have not been able to transmit image data larger than the maximum main scanning length that the apparatus can transmit.

Problems to be Solved by the Invention For this reason, when sending a drawing larger than 8, which allows image data transmission, to a remote location, it is time-consuming to send it by mail.

Honko Meiban, this is a solution to these conventional problems, and it is possible to transmit large drawings in a short period of time using a line, and to transmit this using an ordinary two-image) four-taper transmission device (general The purpose of the present invention is to provide an excellent image data transmitting device that can be received by the 71 Kushimi device.

Means for Solving the Problem In order to solve the above problem, Kikomei's image data transmitting device electrically divides one image into multiple pages, and each of these divided pages is an image data processing unit that adds information that allows correspondence with the original image to the image data;
The apparatus includes an image data compression section that compresses the image data for transmission.

Effect: With the above configuration, the image f-1 is electrically divided into the current number of pages, information that can correspond to the original image is added to this page, compressed, and transmitted.
Larger drawings can be sent to remote locations in a short time and can be received by ordinary image data transmission equipment (ordinary facsimile machines).

Example An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram of an image data sending device according to an embodiment of the present invention, and FIG. An example data processing flow is shown. FIG. 3 is a diagram showing an example of information added to establish positional correspondence with the original image.

In FIG. 1, the 010 unit 11 connects the scanner unit 12, image data storage unit 13, memory unit 14, image data processing unit 115, image data compression/expansion unit 16, and image data transmission unit 17 through the control UTJ bus 20. Control each block. , and each block 12 to 17 has an image bus 21.
is connected, and image data flows through this image bus 27. Depending on the image data processing speed, I! IIJ
Il] bus 20 and image bus 21 may be combined into one bus. The memory section 14 is used as an image data storage section.

As shown in FIG.
Load image data from. Image data processing unit 1
5, the size is enough to transmit image data! ! '
IJ L, I'!
As shown in the divided image 32 in Figure 3, it is expanded into a larger image. Furthermore, the image data processing unit 75 adds 4 information 33 to this margin to establish a positional correspondence with the original image 31. The additional information 33 shown in FIG. The decompression unit 16 compresses the image data, transfers it to the image data transmission unit 17, and sends the image data to the line. Repeat the above for the other pages ■ to ■, dividing one page into 8 pages. and send the image data.

In this way, according to the above embodiment, the image data is divided into multiple pages, glI L, and the margins of the divided images are further divided into multiple pages.
By adding information that can identify which part of the original image is sent, it is possible to determine which part of the original image the divided image belongs to, and it can be received by ordinary image data transmitters such as general facsimile machines. .

Effects of the Invention As described above, according to the present invention, image data can be divided into 871 parts.
By sending images, drawings that are larger than the size that can be sent as image data can be sent and received to remote locations in a short time.
By determining the additional information, the image data can be received by an ordinary image data transmission apparatus (ordinary facsimile apparatus).
