Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an encoded information processing method for an electronic mail system, and particularly to a method for processing encoded information in an electronic mail system.
The present invention relates to an encoded information processing method suitable for processing such as encoding and display position designation of image information in an electronic mail system that simultaneously handles image information such as calligraphy, audio information, and code information created by a word processor or the like.

[Conventional technology]

As a conventional e-mail system,
As described in Publication No. 223939, one of the functions of the mailbox that stores and controls messages is to create a field that can define message attributes, and to add response request attributes to the message so that the receiving terminal can It is known that when an attribute of a reply to this reply request is added, a reply message is generated from the sender address, receiver address, and input data, and is sent back.

However, no consideration was given to encoding processing of image information such as handwritten characters and calligraphy and drawings.

[Problem that the invention seeks to solve]

Generally, image information has a large amount of information because the unit of information is one pixel. Therefore, rather than transmitting image information as is, predetermined encoding rules (for example, MM, MR,
(MMR, etc.) and is then encoded and transmitted.

However, in the prior art, when encoding image information, it is impossible to specify the encoding rules, reduction/enlargement ratio, screen position in the transmitted message, etc. Therefore, the selection of encoding rules according to the content and importance of image information,
Another problem was that it was impossible to display the image information on the same screen as the code information on the receiving terminal side.

The present invention was developed in view of the problems of the prior art described above, and it specifies encoding rules and reduction/enlargement ratios according to the content and importance of image information, and the receiving terminal side uses the same code information as the code information. The object of the present invention is to provide an encoded information processing method for an electronic mail system that makes it possible to display image information on a screen.

[Means for solving problems]

In the encoded information processing method of the e-mail system of the present invention, the sending terminal receives input code information and
The audio information is transmitted without being encoded, the input image information is encoded and transmitted after data compression, and the receiving terminal transmits the received code information/
Audio information is displayed as is without being decoded, and received image information is decoded and data expanded before being displayed. In particular, when inputting image information to a sending terminal, The system is characterized in that attributes are input for each piece of image information, and according to the attributes, the transmitting terminal performs processing such as encoding, and the receiving terminal performs decoding and display processing.

[Effect]

As described above, the transmitting terminal inputs the attributes of the image information at the same time as inputting the image information.
The attributes may include, for example, an encoding rule, a position in a message screen to be sent, and a reduction/enlargement rate of image information. Then, the sending terminal, according to the encoding rules included in the attributes of the image information,
The image information is encoded, the above attributes are added to the encoded image information, and the result is transmitted.

The receiving terminal decodes the received encoded information according to the encoding rule indicated in the attribute and displays the image information at a specified position in the message screen at a specified reduction rate or enlargement rate.
