A mobile terminal device, an information processing method and an information processing program make it possible to select an optional function process during execution of a specific function process, such as a dictionary function process during a call, and executes simultaneously each function process or make that execution possible. Also, the device, the method and the program make it possible to copy information indicated in an optional screen of an indication part, and make it possible to indicate that information in a screen of a different function process. That is, the mobile terminal device has a communication processing part, a function processing part, a selection input part (an input operation part) and a control part. The communication processing part executes each communication process of voice communication, such as telephonic voice communication, and non-voice communication, such as non-voice data communication. The function processing part executes a function process selected from one or more function processes except the communication processes. The selection input part selects a function process to execute from one or more function processes which have been prepared or are prepared in the function processing part, by means of an operational input. The control part executes one or more function processes selected from one or more function processes including the communication processes, or controls to make that execution possible.
