ABSTRACT:
A facsimile apparatus according to the present invention is arranged to evaluate the density of an original image to be transmitted and/or the resolution of a communication installed on the reception side, determine a resolution for transmission on the basis of the result of the evaluation, and transmit the image at such a resolution. Accordingly, it is possible to transmit the image at an optimum resolution which corresponds to the resolution of the communication device installed on the reception side and/or the density of the original image.
