7. A power control method comprising:
performing, by an electronic device, communication with a communication terminal to acquire an address of the communication terminal; and
shifting an own power state of a power control unit of the electronic device from a standby state where power is supplied only to a minimum function to a quick start state where power is supplied to a function other than a presentation function to a user and is not supplied to a function that is a presentation function to the user, when the acquired address matches a registered address, wherein, when a user operation is performed after the own power state is shifted to the quick start state, the own power state is shifted to an ON state where power is supplied to each unit that is started in the quick start state and at least one additional unit;
when the power control unit is in the quick start state, extracting information in accordance with user preference information which is stored in association with the address of the communication terminal when the acquired address matches the registered address, and providing the extracted information when the own power state is shifted to the ON state by the user operation.
8. A non-transitory storage medium on which is recorded a program which causes a computer to function as:
an address acquisition unit that performs communication with a communication terminal to acquire an address of the communication terminal which is provided by a wireless function;
a power control unit that shifts its own power state from a standby state where power is supplied only to a minimum function to a quick start state where power is supplied to a function other than a presentation function to a user and is not supplied to a function that is a presentation function to the user, when the address acquired by the address acquisition unit matches a registered address, wherein, when a user operation is performed after its own power state is shifted to the quick start state, the power control unit shifts its own power state to an ON state where power is supplied to each unit that is started in the quick start state and at least one additional unit;
a preference information storage unit that stores user preference information in association with the address of the communication terminal; and
an information providing unit that, when the power control unit is in the quick start state, extracts information in accordance with the user preference information stored in the preference information storage unit in association with the acquired address when the address acquired by the address acquisition unit matches the registered address, and provides the extracted information when its own power state is shifted to the ON state by the user operation.
9. The non-transitory-storage medium according to claim 8 , wherein the wireless function is Bluetooth.
10. The non-transitory-storage medium according to claim 8 , wherein the wireless function is WiFi.
11. An electronic device comprising:
an address acquisition unit that performs communication with a communication terminal to acquire an address of the communication terminal which is provided by a wireless function;
a power control unit that shifts its own power state from a standby state where power is supplied to less function than a quick start state where power consumption is larger than the standby state, when the address acquired by the address acquisition unit matches a registered address,
wherein in the standby state power is supplied to at least the power control unit and a radio control unit, and power is not supplied to a function that is a presentation function to a user,
wherein, when a user operation is performed after its own power state is shifted to the quick start state, the power control unit shifts its own power state to an ON state where power is supplied to each unit that is started in the quick start state and at least one additional unit;
a preference information storage unit that stores user preference information in association with the address of the communication terminal; and
an information providing unit that, when the power control unit is in the quick start state, extracts information in accordance with the user preference information stored in the preference information storage unit in association with the acquired address when the address acquired by the address acquisition unit matches the registered address, and provides the extracted information when its own power state is shifted to the ON state by the user operation.
12. The electronic device according to claim 11 , wherein the radio control unit performs pairing in advance by the wireless function.
13. The electronic device according to claim 11 , wherein the wireless function is Bluetooth.
