Abstract:
1. An image photographing device, which converts an optical image of a subject into an electric signal by an image pick up device, and stores image data by the electric signal in an information recording medium, comprising: a communication interface configured to communicate the image data; a determination device configured to determine that a device connected to the communication interface is an external device when a continuous voltage is applied to a power source line of the communication interface in response to connection of the device, the determination device determining that the device is a release device when a pulsed voltage is applied to the power source line of the communication interface in response to connection of the device to the communication interface; a communication process device configured to conduct a communication process with the external device when the determination device determines that the external device is connected; and a photographing process device configured to conduct a photographing process when the determination device determines that the release device is connected, wherein the continuous voltage has a predetermined voltage level continuously applied from a time of connection of the device to the communication interface to a time of disconnection of the device.
