Communication terminal device

Abstract

The present invention discloses a communication terminal device, which is provided with a mail body encoding image data and an encoding mode judgement unit judging the encoding mode of the mail body, and the judgement unit at least judges an email header message which is composed of communication management information (header information) containing information related to the encoding mode and sent and received by emails.

Description

technical field [0001] The present invention relates to a communication terminal device with the function of sending and receiving e-mails, such as a facsimile machine that can send and receive e-mails when connected to a computer communication network such as the Internet. Background technique [0002] There are two types of facsimile machines as communication terminal devices: one is connected to analog lines; the other is connected to digital lines. The former is generally called a G3 machine, and the latter is generally called a G4 machine. However, generally speaking, the G3 function is also included in the G4 machine. [0003] In recent years, computer communication networks such as interconnection networks have been widely used. The reason is the following two aspects: one is that the error correction function of the computer communication network is very good; Communication with domestic computing but also with global computers. [0004] The conventional G3, G4 fa...

Problems solved by technology

As in the facsimile communication mentioned above, usually the image data to be sent and received is converted into e-mail form data, and then sent and received as e-mail by means of a computer communication network. When the fax image data is coded with a specific coding method, it is possible to reproduce it after decoding. Therefore, even if emails with other coding methods can be received from the computer communication network, after the data is processed, but cannot display the original content
