IMAGE DATA TRANSMITTING METHOD AND FACSIMILE-TYPE ELECTRONIC MAIL EQUIPMENT USING ELECTRONIC MAIL

摘要

PROBLEM TO BE SOLVED: To communicate with communication equipments having mutually different paper size by reducing image data at the reception side to cancel the difference in the paper sheet size at a transmission side and the reception side which occurs at the time or transmitting/receiving image data as an elec tronic mail. SOLUTION: The electronic mail received in a reception side equipment is obtained by reading image data from a scanner part 11, executing compression in a compression/extension part 8 and executing conversion into an electronic mail format by a format converting part 4. The electronic mail is converted into image data by a format reverse converting part 5. Then, the paper sheet size and resolution are obtained from the image data. Then, compressed image data is extended and the paper sheet size and the resolution of image data are compared with the ones which are dealt in the reception side equipment. When the ability of the reception side equipment is lower, reduction to the paper sheet size which is dealt at the reception side is executed in a reducing part 6 so as to execute printing.
