IPC: H04N1/32
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a communications terminal that can minimize deterioration in the image quality to the utmost even when applying reduction or resolution conversion to the image data. SOLUTION: The communications terminal applies multi-value reduction or resolution conversion to black/white multi-value image data obtained by reading depending on the destination capability, that is, the recording paper capability and the recording state resolution capability of the destination. The communications terminal applies binary processing and encoding to the image data subjected to multi-value reduction or resolution conversion, stores the result once to an image memory 80, read the data and faxes the read data to the destination. Thus, the image data after reduction or resolution conversion are nearly the same as the image data on the original different from a conventional configuration where the image data are subjected to binary reduction or resolution conversion.  Thus, the destination can record nearly the same received image data as the image data on the original on recording paper. In other words, since the communications terminal applies multi-value reduction or resolution conversion to the image data, the deterioration in the image quality can be minimized.
