When image data obtained by an imaging apparatus such as a digital camera are sent via a wireless communication system, power consumption by a wireless communication apparatus installed in the imaging apparatus is reduced as much as possible. First communication means receives base station information from a base station in a mobile phone communication network, and judgment means judges whether or not a coverage area of the wireless communication equipment exists in a coverage area of the base station, based on the base station information. If a result of the judgment is affirmative, second communication means that carries out data communication is activated, and the image data obtained by photography are sent to the wireless communication equipment.
