ABSTRACT:
A facsimile apparatus has a first coder for coding image data by a one-dimensional coding method or a two-dimensional coding method, and a second coder for performing coding by a second coding method different from these coding methods. When the amount of code of one line coded by the first coder exceeds a predetermined amount, coding by the first coder is suspended and the image data are coded upon making a changeover to coding by the second coder. In addition, a code resulting from coding by the one- or two-dimensional coding method and a code resulting from coding by the second coding method can be received and decoded.
