An electronic camera includes a wireless communication means for connecting to a wireless network; a transfer control means for transferring a captured image to a server through the wireless network connected by the wireless communication means; a power supply judgment means for judging whether or not power supply from outside has started; and a power source switching means for switching a power source of the electronic camera to ON or OFF. When the power source of the electronic camera has been switched to OFF by the power source switching means and if it has been judged by the power supply judgment means that supply of the power has started, the transfer control means transfers the captured image to the server, and when the power source of the electronic camera has been switched to ON by the power source switching means and if it has been judged by the power supply judgment means that supply of the power has started, the transfer control means prohibits transfer of the captured image to the server.
