Abstract: A blank determining section performs scanning of a text part of e-mail when receiving e-mail. The scanning of text part is carried out up to a next boundary. After the end of scanning, the blank determining section determines whether or not there is any code other than unprintable codes such as a blank, a tab, a line feed, and the like. Since the text part is composed of only a line feed, the blank determining section clears data of the text part from a mail reception memory area. An image part is normally printed. As a result, the printing of text part is skipped, and only the image part is printed. This makes it possible to prevent a useless output and an output of inconvenient information.

Abstract: An image coding method that compresses an image read through an optical system. An image separation section carries out image area decisions in tile (macro block) units to separate the image into photographic image tiles and character image tiles. A layer separation section performs layer separation pixel by pixel to separate each pixel into pixels belonging to a background and pixels belonging to a foreground.

Abstract: When an IFAX processing section transmits image information using e-mail, a timer monitoring section starts the count of a timer. After starting the count, a received mail determining section determines whether or not a timeout occurs. Also, the received mail determining section determined whether an error mail of a current job or a DSN of the current job is received. In the case of the timeout, when the notification content of the error mail or the DSN is an abnormal end, a transmission selecting section instructs a FAX control section to transmit an image information file of the current job to a telephone number. Thereafter, the transmission selecting section instructs an image information managing section to erase an image information file corresponding to a file name of the current job. This makes it possible to insure a real-time property as making use of advantages of e-mail.

Abstract: A plurality of destination mail addresses for broadcast transmission input from a panel control section is temporarily stored in an address data buffer. An address reading control section reads the destination mail addresses from the address data buffer in order to divide the plurality of destination mail addresses to a plurality of groups in unit of setting value M. A mail creating section creates e-mail directing to a destination mail address belonging to each group. This makes it possible to limit the number of destination mail addresses, which is input to a destination filed [To:] of one e-mail, to the setting value M. Also, this makes it possible to prevent a header portion from being needlessly increased at the time of broadcast transmission.
