Abstract

PROBLEM TO BE SOLVED: To transmit a still picture always in a correct original size by transferring picture data and original size information of a still picture read by a reader. SOLUTION: An original of a size A4, e.g. on which the still picture to transfer is plotted is placed on the scanning part of a color copying machine 4 on a transmission side functioning as the reader, and the number of printing copies to transmit and resolution at the time of scanning the original are set by the key operation of a color still picture transmitter 2 to transmit. Then the color copying machine 4 receiving the printing instruction of a receiving side terminal prints a received picture according to original size information, data on the number of printing copies and resolution. As original size information obtained by scanning the still picture by the reader is transmitted with picture data like this, it is prevented to transmit picture data because of the specifying of a wrong original size. Consequently, an operation cost and a communication cost are reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still image transmission method for transmitting a still image via a communication line, and more particularly to a still image transmission method capable of outputting a transmitted still image at a receiving terminal in an accurate size. .

[0002]

2. Description of the Related Art In a conventional still image transmission method, the original size of a still image to be transmitted is designated by a key operation of a transmitting terminal and the image data of the designated original size is transmitted to a receiving terminal.

[0003]

However, this conventional method has a disadvantage that image data of a size smaller or larger than the actual document size is transmitted if the document size is specified incorrectly. It was For example,
If you want to transmit an A4 size original and specify B5 size due to an error in key operation, the sending terminal will
Image data obtained by cutting a 4-size document into a B5 size was transmitted. In this case, the image data has to be transmitted again, which causes an inconvenience that the work cost and the communication cost increase.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a still image transmitting method capable of always transmitting a still image to be transmitted with a correct document size.

[0005]

In the still image transmitting method of the present invention, the transmitting terminal transfers the image data and the document size information of the still image read by the reading device, and the receiving terminal receives the image data and the document size. A still image is formed and output based on the information.

According to the present invention, the sending terminal side reads the original size together with the image data when the reading device scans the still image, and transfers the read image data and the original size information. Images can always be output in the correct document size.

A color still image transmission apparatus is provided on a communication line 1 such as ISDN (Integrated Services Digital Communication Network). 2 shows a configuration in which a color copying machine 4 is connected via the external interface unit 2 and the external interface unit 3.

FIG. 2 is a block diagram of the color still image transmission device 2. In the figure, a SCSI (small computer system interface) control unit 20 is provided to enable connection using the international standard SCSI, and further, a DMA for transferring data from the SCSI control unit 20. (Direct memory access) Control unit 2
1. Image memory 2 for internally storing transfer data
2. Image control unit 2 for controlling the image memory 22
3. A panel control unit 24 for controlling the lower-level color copier 4 by a panel instruction, a line control unit 25 for passing data held in the image memory 22 or data from a line, and the entire system It has a main control unit 26 for operating, a program memory 27 for storing various programs, and a work memory 28.

Next, the processing procedure of the still image transmission method according to the embodiment of the present invention will be described with reference to the flowcharts shown in FIGS. 3 and 4. In addition, here A4
A case where a still image drawn on a size original is transmitted will be described as an example, and a device on the transmission side is denoted by reference numeral s and a device on the reception side is denoted by reference symbol r.

First, an A4 size document with a still image to be transmitted is placed on the scanning section of the color copier 4s on the transmission side, which functions as a reading device (step S1), and the number of copies to be transmitted and the document to be transmitted to the other terminal. The resolution at the time of scanning is set by the key operation of the color still image transmission device 2s on the transmission side (step S2).

Then, the dial number of the destination terminal as the transmission destination is set (step S3), and the start button is pressed (step S4). Then, the color still image transmission device 2
A scan command is issued from s to the color copying machine 4s via the external interface unit 3s (step S5).

In response to this command, the color copying machine 4s scans the still image drawn on the document (step S
6) The image data and the document size information (A4 size in this case) obtained thereby are sent to the external interface unit 3s. Next, the color still image transmission device 2
s captures the image data and the document size information sent to the external interface unit 3s (step S7), and after the capture process is completed, connects the color still image transmission device 2r on the receiving terminal side via the communication line 1 to the line connection. Perform (step S8).

As a result, if the line connection is abnormal (step S9), the color still image transmission device 2s on the transmission side displays an error message to that effect (step S10), and the process ends. If the line connection is normal, the transmission side color still image transmission device 2s transmits the document size information, the image data, the number of copies and the resolution data to the reception side color still image transmission device 2r (step S11).

The color still image transmitting apparatus 2r on the receiving side sends the data of the document size, the image data, the number of prints and the resolution received during the transmission to the external interface unit 3r. When the transmission of the image data is completed, the color still image transmission device 2s disconnects the line connection.

When transmission of all image data and the like is completed in this way, the color still image transmission device 2r on the receiving side receives the color copying machine 4 via the external interface unit 3r.
A print command is issued to r (step R1). Upon receiving the print command, the color copying machine 4r prints the received image according to the original size information, the number of prints, and the resolution data (step R2).

If the printing condition is good (step R
3) After the printing is completed, the color still image transmission device 2r deletes the document size information, the image data, the number of prints and the resolution data stored in the external interface unit 3r (step R4), and ends the process. .

If printing becomes impossible due to a paper jam or the like during printing (step R3), the color still image transmission device 2r displays an error message (step R5), and the color copying machine 4r fails to print. The cause is investigated (step R6).

To print again (step R
7) After solving the cause of failure, press the print button by operating the key of the color still image transmission device 2r (step R
8) Then, press the start button (step R9). As a result, the process returns to step R1 and the printing process is executed again.

If printing is not performed (step R7),
The delete button is pressed by the key operation of the color still image transmission device 2r (step R10), and then the start button is pressed (step R11). As a result, the original size information, the image data, the number of prints, and the resolution data remaining in the external interface unit 3r are deleted (step R12), and the process ends.

[0020]

According to the present invention, since the original size information obtained by scanning the still image to be transmitted by the reading device is transmitted together with the image data, it is possible to avoid unnecessary transmission of the image data due to the designation error of the original size. Therefore, the work cost and the communication cost can be reduced.
