When the result is YES, stored color image data are converted into the color images of the specified number of colors by executing a prescribed color reduction processing so as to turn the number of the colors to the specified color reduction instructed number of the colors (S107). To the converted color image data, a prescribed color encoding processing is applied in an encoding/decoding part and the color image information to be transmitted is prepared (S108). Then, the specified destination is called and the prepared color image information is transmitted to the destination (S109).
