A mobile terminal apparatus having a radio communication interface (28) for radio communication includes a touchscreen device (22). A program receiver (51) receives program (CAP) from a server apparatus (16) storing plural sets of program, for communication access to an imaging apparatus (13A-13C). A controller (50) functions according to the received program, drives the touchscreen device to display a user interface view (53, 55, 55A-55C, 59), and causes the radio communication interface to perform the communication access to the imaging apparatus. Preferably, the controller transmits a signal to and receives a signal from the imaging apparatus by the communication access. Furthermore, the touchscreen device as an information input device inputs modality information for recognition of the imaging apparatus. The program receiver transmits the input modality information to the server apparatus, and acquires the program according to the modality information from the server apparatus.
