摘要

A communication terminal device (1) performs communication with another communication terminal device through a network. The communication terminal device (1) includes a storage unit (250) configured to store therein thresholds for communication speed and display methods for displaying states of the communication speed for respective groups into which communication quality is categorized; an acquiring unit (220) configured to acquire a communication speed during communication; a determining unit (230) configured to compare the acquired communication speed with the thresholds for the communication speed stored in the storage unit and determine a display method for displaying a state of the acquired communication speed; and a display unit (240) configured to display the state of the acquired communication speed with the determined display method.
