Abstract:
1. A communication terminal device comprising: means for storing, wherein when receiving image data by facsimile from a communication terminal device of another end, the means for storing stores a measured average value and fluctuation of an eye quality monitor (EQM) value of the image data and a number of error lines of the received image data as an EQM data table; and means for controlling to receive a training signal from the communication terminal device of the other end in a past facsimile communication, execute a training process, measure an average value and fluctuation of an EQM value of the training signal, compare the measured average value and the fluctuation of the EQM value with the average value and the fluctuation of the EQM value stored in the EQM data table, and execute the training process again when the measured average value and the fluctuation of the EQM value do not match the average value and the fluctuation of the EQM value stored in the EQM data table.
