Digital camera and system thereof
In the digital camera that can be used in connection to a mobile phone or other mobile electronic devices and the system thereof, a battery mounted in each device is shared to allow power to be supplied between the devices, and allow both devices to be used for longer hours. The digital camera and the mobile phone are electrically connectable by a connection cable. Generally, a power supply selection switch is set to A, and a power supply selection switch is set to D. The digital camera receives power supplied from a battery, and the mobile phone receives power supplied form a battery. From this state, when the power supply selection switch is switched to C, power is supplied from the battery to the mobile phone. On the other hand, when the power supply selection switch is set to B, and the power supply selection switch is set to D, power is supplied from the battery of the mobile phone to the digital camera.
1 . A digital camera connectable to a mobile electronic device capable of being driven by a battery, the digital camera comprising:
a first battery which provides a supply source of power necessary to operate the digital camera;
a connecting unit which electrically connects to the mobile electronic device;
a power input terminal which receives power supplied from a second battery mounted in the mobile electronic device connected via the connecting unit; and
a power supply selection device which selectively switches a power supply such that power is supplied from one of the first battery and the second battery.
2 . The digital camera according to claim 1 , further comprising a power output terminal capable of supplying power from the second battery to the mobile electronic device connected via the connecting unit.
