The data is converted into a code, converted into text so as to be data in a predetermined e-mail format, and the data in the e-mail format is transmitted according to an existing e-mail protocol.

FIG. 3 shows a communication device 1 according to the first embodiment.
12 is a flowchart showing the flow of the process of FIG.

First, the user sets a document on a document table or a document feeder (3-1), and when an operation section 2-17 selects a destination address and instructs reading of a document image (3-3-1). 2), the CPU 2-3 is a reading unit 2-1
4 scans the original and reads the image on the original. The image data corresponding to this image is compressed and decompressed by the compression / expansion unit 2-12.
A compression process such as R, MR, and MH is performed, and the image data is temporarily stored in the storage memory 2-5 as encoded image data. This process is repeated for all pages of the original to be transmitted.

The address selection in 3-2 is performed by operating the operation unit 2-17 by the user.
The address book is displayed on the display unit of the user, and the user selects a desired destination from the address book.
It is assumed that the e-mail address of er2 has been selected.
Here, it is assumed that the operation unit 2-17 is set to read a document as a monochrome image and encode it by MH. At this time, the format of the attached file (here, single page TIFF) and the source user (here, e-mail@aaa.bbb.co.j) are used.
p), Subject (here, Scan), reply destination address (here, user1@aaa.bbb.co.
jp), the description contents of the body part, etc. are also specified. These pieces of information are transmitted from the operation unit 2-17 to the CPU 2-3, and reading control and encoding control are performed.
Reference numeral 3 reads out a specified destination e-mail address from those stored in the RAM 2-4 or the storage memory 2-5.

Next, in the electronic mail, since the binary image data cannot be directly transmitted, it is converted into a format that can be handled by the electronic mail as follows.

First, in response to the specification of the e-mail address, the CPU 2-3 sets the image data in the storage memory 2-5 encoded by the compression / expansion unit 2-12 to MH at the top of the image data.
TIFF image data is created by, for example, adding IFF CLASS F header information (3-4). Here, single page TIFF, so 1 per page
Create as a file.

Then, the CPU 2-3 converts the TIFF image data from the binary format to the base 6
4 to text data by conversion (3-5), 1
Each time the conversion for a page is completed, it is determined whether or not the upper limit set value previously set in the communication device 1-5 has been exceeded (3-6). Here, the upper limit set value is set in the operation unit 2-17.
Is an amount of data that can be arbitrarily set by the user using, and this setting is stored in the RAM 2-4 or the like. The upper limit can be set to a different amount for each destination.

Here, the TIF converted to text data
If it is determined that the F image data has exceeded the upper limit set value,
It is determined whether the number of converted image data pages exceeds one, that is, whether there is at least one converted page (3-7). If it exceeds one page, the TIFF image data for the last page is deleted from the current target e-mail data, and the deleted TIFF image data is stored as the next e-mail data in the storage memory 2-5. (3-8).

If the converted image data does not exceed one page, since the image data for one page has already exceeded the upper limit set value, it cannot be transmitted with this setting. Data is discarded without transmission control (3-9), and the result is stored in RAM as an error.
It is stored in 2-4 or the like (3-10). Here, if at least one of the transmission target images includes a page exceeding the upper limit value, all images are not transmitted as an error. This is to eliminate the inconvenience of transmitting incomplete data as a whole.

When it is determined in step 3-6 that the data does not exceed the upper limit set value, or when the data of the last page is deleted in step 3-8, the T
The IFF image data is stored in the storage memory 2-5 as an attached file of the e-mail (3-11). After the processing in step 3-8, a new file is created from the next image data, and if not, image data is added to one file.

If there is data for the next page (3
-12), repeat the processing from step 3-5.

When the processing of all the image data to be transmitted as an attached file of an e-mail is completed, the CP
U2-3 is all TIFFs converted to text data
The image data is edited into an e-mail format by adding a known e-mail header to the image data (3-13).

FIG. 4 shows an example of data edited in an electronic mail format. This data is a text file described in MIME format. The text file is "--- B
"oundary ----" is divided into 5 parts by the separator line, the first part describes the mail header, the second part describes the transmission information (body part), and the third, fourth and fifth parts are files. , And blank information is inserted and identification information such as base64 encoding method for converting binary data into a character string corresponds to image data of pages 1, 2, and 3 of the transmission image of all 10 pages. Data is described as a character string.

In FIG. 4, From, T in the header portion
The o, Reply-To, and Subject fields describe what is input or specified by the user from the operation unit 2-17 in step 3-2 at the time of transmission instruction.
Then, in the place where "Message" is, the content input by the user as the text from the operation unit 2-17 is described. However, when the e-mail is divided into a plurality of parts as in the present embodiment, n / m is automatically added to the number of divisions m and n indicating the number of divisions after the subject specified by the user. (In this example, one of the three
Th).

Hereinafter, the items enclosed by [] and their contents are automatically generated and described when the electronic mail data is created. [Email content] indicates that an image in TIFF format is attached, [Source host address] indicates the email address of the sender, [Send date and time] indicates the date and time when the sending of the email is started, [ The “total number of transmitted images” indicates the total number of pages of the image to be transmitted (here, the image of 10 pages is transmitted in three divided portions, and in the first mail, three pages are transmitted). [Number] indicates the number of divided emails including the image to be sent, [Number of pages sent by this email] indicates the number of pages sent by this email out of the total number of pages sent by this email, and [File name] ] Indicates the file name of the file attached to this mail.

The file name is the source user name (im
ail1), transmission date and time (19981031), counter (01 to 03: a different number is serially assigned to each file), communication number (10: a series of e-mails,
In this case, the file is common to the three divided e-mails and is distinguished from another e-mail), followed by an extension indicating the type of file (here, TIFF indicating .tiff).
Is automatically given.

The portion of the “X page of the image encoded by base64” describes the actual contents of the file converted to text.

When such data in the e-mail format is completed, an external e-mail server (here, e-mail) is sent via the LAN I / F 2-6 (or the line I / F 2-7 in the case of dial-up). A connection request is issued to the server 1-2), authentication is performed, and communication with the electronic mail server 1-2 is established (3-14).

When the communication is established, the CPU 2-3
Is SMTP (Simple Mail Transfer)
r Protocol), and sequentially transmits the e-mail data created earlier (3-15). When transmission of all data is completed, communication with the electronic mail server 1-2 is released (3-16). At the same time, the transmission date and time, the destination, the source, a part of the image, the number of pages, the data amount, the number of divisions, and the like are stored in the storage memory 2-5 as the history (3-
17).

The e-mail transmitted as described above is sent to P-mail in response to a request from the e-mail client 1-10.
E-mail client 1-10 according to the procedure of OP3
Imported by the UA above, the TIFF file is decoded and viewed.

In the above example, the single page TIF
Although the F type was used, the present invention is not limited to this.
It is needless to say that it is possible to set a multi-page TIFF (one file with a plurality of pages) or JPEG by setting from 7.

Similar processing as described above can also be performed by an Internet FAX that transmits image data as an attached file of an electronic mail. At this time, different settings can be made for the electronic mail and the Internet FAX.

Further, regarding the setting and comparison of the upper limit value, the above-mentioned one is converted into a text for e-mail and then compared. However, the upper limit value may be determined at a previous stage.

Further, in the above-described method, the e-mail is divided up to the previous page every time the upper limit is exceeded. However, the e-mails are divided into groups so that each e-mail is almost equal. You can also.

Further, the file may be divided based on the number of files (the number of pages).

The attached file is also read by the reading unit 2-14.
The image may be an image from another source as well as an image from, or may be a binary file other than the image.
Of course, it can be easily realized by introducing software corresponding to the present embodiment into a general-purpose personal computer.

According to the above-described embodiment, even large-capacity image data can be appropriately transmitted by e-mail even if the e-mail server on the transmission side or the reception side has a limited capacity.

Further, since the limit value is also set in advance, it is possible to automatically divide and transmit the data without the user being conscious each time.

Second Embodiment Next, a second embodiment will be described.

The configuration of the system and the configuration of the communication device 1-5 are the same as those of the first embodiment, and the description is omitted here.

The flow of processing of the communication device 1-5 according to the second embodiment will be described with reference to the flowchart shown in FIG.

Steps 5-1 to 5-5 are the same as steps 3-1 to 3-5 of the first embodiment, and a description thereof will be omitted.

In step 5-6, when all the image data to be transmitted have been converted into character string data,
Judge whether the data amount exceeds the upper limit set value.

If it is determined that the number of pixels exceeds the range, the resolution (pixel density) of the converted image data stored in the storage memory 2-5 is roughly converted by the pixel density conversion unit 2-11 to reduce the number of pixels. The data amount is reduced by reducing (5-7).

Then, it is determined whether or not the dropped resolution is lower than the lower limit set value (5-8). In the present embodiment, the lower limit value (d
pi) can be set by the operation unit 2-17 and stored in the RAM 2-4.

If the lower limit has been exceeded, a message to that effect is displayed on the display unit of the operation unit 2-17 to notify the user (5-9), and a display method other than e-mail is also displayed on the display unit. do. The communication device 1-5 uses a facsimile (existing G3 / G
4) Since it has a transmission function of Internet FAX, it displays that these can be selected. Of course, this is the case when the destination has such a receiving function.
The address book of the communication device 1-5 is grouped for each destination, and each transmission method is associated. In this case, it is assumed that the upper limit of the Internet FAX and the electronic mail is larger in the Internet FAX.

When the user selects another transmission method from the displayed contents by operating the operation unit 2-17, the image data is reconverted according to the selected method (protocol) and transmitted to the same destination ( 5-12). The resolution at this time is based on a resolution that does not fall below the lower limit.

On the other hand, if it is determined that the value does not fall below the lower limit set value, the processing is repeated from step 5-4 again based on the image data with the reduced resolution.

When the amount of data that can be transmitted by e-mail is reached, it is stored in the storage memory 2-5 as an e-mail attached file (5-14).

Next, an e-mail format is edited by adding an e-mail header to the attached file. This format is as described above. However, items related to division are not included.

Hereinafter, in steps 5-15 to 5-18,
It is transmitted as an e-mail in the same manner as in steps 3-14 to 3-17, and the result is stored.

As described above, according to the present embodiment, even when the amount of data becomes too large when transmitting an e-mail attached with image data, the data amount of the image data is reduced to form one e-mail. Can be sent.

It is to be noted that by appropriately combining the processes of the above-described first and second embodiments as follows, a system with improved usability can be obtained.

When the value exceeds the upper limit set value (step 3
In 6), whether to use the processing of the first embodiment or the second embodiment (steps 5-7 to 5-12) is set by the operation unit 2-17.

Alternatively, if it is determined in step 5-8 of the second embodiment that the value is below the lower limit, the division is made as in the first embodiment (steps 3-8 and below).

Alternatively, if it is determined in step 3-7 of the first embodiment that it does not exceed one page, a process of lowering the resolution is performed as in step 5-7 of the second embodiment.

Alternatively, step 5-11 of the second embodiment
When the other transmission method is presented, the processing of the first embodiment is also selected.

In addition, the processing of the first and second embodiments and other processing are appropriately combined according to the designation of the user.

Even if the present invention is applied to a system composed of a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), it is composed of one device (for example, a copying machine or a facsimile machine having a communication function). You may apply to an apparatus.
