PROBLEM TO BE SOLVED: To provide communication equipment which can surely and efficiently transmit information whose quantity is enormous. SOLUTION: When the data quantity of electronic mail data (electronic mail data including multivalue picture information) transmitted by a transmission means 206 is larger than prescribed (transmission possible upper limit) which is previously set (step S307), multiple picture information of electronic mail data is reduced in number of colors (S309). The data quantity of electronic mail data transmitted by the transmission means 206 is automatically adjusted to data appropriate for transmission.
