Abstract

The disclosure is directed to a method of providing location information for a mobile electronic device and a mobile electronic device using the same method. In one of the exemplary embodiments, the mobile electronic device would receive a first signal that indicates capturing a multimedia file. In response to receiving the first signal, the mobile electronic device would transmit to an external device a second signal in response to receiving the first signal. In response to transmitting the second signal, the mobile electronic device may receive from the external device a first location information or an ephemeris. The mobile electronic device may then determine the first location information either based on the first location information as received or based on the ephemeris. Also, the mobile electronic device may associate the multimedia file with the first location information.

First claim

What is claimed is:

1 . A method of providing location information applicable to a mobile electronic device comprising:
receiving a first signal that indicates capturing a multimedia file transmitting a second signal to an external device in response to receiving the first signal; receiving a first location information or an ephemeris from the external device in response to transmitting the second signal; determining the first location information either as received or based on the ephemeris received; and associating the multimedia file with the first location information.

2 . The method of claim 1 , wherein receiving the first location information or the ephemeris from the external device in response to transmitting the second signal comprising:
receiving the ephemeris from the external device in response to transmitting the second signal; and calculating the first location information based on the ephemeris.

3 . The method of claim 1 further comprising:
capturing a second multimedia file before capturing the multimedia file, wherein a second location information of the second multimedia file is not available when the second multimedia file is captured;
estimating the second location information of the second multimedia file based on the location information of the multimedia file; and
associating second location information of the second multimedia file with the second multimedia file.

4 . The method of claim 1 further comprising:
capturing a third multimedia file before capturing the multimedia file, wherein a third location information of the third multimedia file is not available when the third multimedia file is captured;
receiving a third location information from the external device after capturing the multimedia file; and
associating the third location information with the third multimedia file.

5 . The method of claim 1 further comprising:
capturing a fourth multimedia file before capturing the first multimedia file, wherein a fourth location information of the fourth multimedia file is not available when the fourth multimedia file is captured;
receiving the ephemeris from the external device after capturing the first multimedia file;
determining the fourth location information based on the ephemeris; and
associating the fourth location information with the fourth multimedia file.

6 . The method of claim 1 further comprising:
receiving an auxiliary information from the external device that is one or a combination of a date information, a weather information, a temperature information, and an atmosphere pressure reading; and
associating the multimedia file with the auxiliary information.

7 . The method of claim 1 further comprising:
receiving a sensor reading that is one or a combination of a G-sensor reading, a barometer reading, an atmosphere pressure reading, a motion sensor reading, and a gyroscope reading; and
associating the multimedia file with the sensor reading.

8 . The method of claim 1 , wherein transmitting the second signal to the external device in response to receiving the first signal comprising:
transmitting the second signal to the external device in response to receiving the first signal via a peer to peer (P2P) wireless interface, which is one of a Bluetooth interface, a near field communication (NFC) interface, and a Wi-Fi Direct interface.

9 . The method of claim 1 , wherein the multimedia file is one of a still image and a video.

10 . The method of claim 1 , wherein receiving the first signal that indicates capturing the multimedia file comprising:
receiving the first signal in response to an activation of a shutter button or an activation of a start button to start capturing the multimedia file which is a video.

11 . A mobile electronic device comprising:
a wireless interface; and a processing unit coupled to the wireless interface and is configured at least for:
receiving a first signal that indicates capturing a multimedia file;
transmitting via the wireless interface a second signal to an external device in response to receiving the multimedia file;
receiving via the wireless interface a first location information or an ephemeris from the external device in response to transmitting the second signal;
determining the first location information either as received or based on the ephemeris received from the external device; and
associating the multimedia file with the first location information.

12 . The device of claim 11 , wherein the processing unit is configured for receiving via the wireless interface the first location information or the ephemeris from the external device in response to transmitting the second signal comprising:
receiving via the wireless interface the ephemeris in response to transmitting the second signal; and calculating the first location information based on the ephemeris.

13 . The device of claim 11 , wherein the processing unit is further configured at least for:
capturing a second multimedia file before capturing the multimedia file, wherein a second location information of the second multimedia file is not available when the second multimedia file is captured; estimating the second location information of the second multimedia file based on the location information of the multimedia file; and associating second location information of the second multimedia file with the second multimedia file.

14 . The device of claim 11 , wherein the processing unit is further configured at least for:
capturing a third multimedia file before capturing the multimedia file, wherein a third location information of the third multimedia file is not available when the third multimedia file is captured; receiving a third location information after capturing the multimedia file; and associating the third location information with the third picture.

15 . The device of claim 11 , wherein the processing unit is further configured at least for:
capturing a fourth multimedia file before capturing the multimedia file, wherein a fourth location information of the fourth multimedia file is not available when the fourth multimedia file is captured; receiving the ephemeris after capturing the multimedia file; determining the fourth location information based on the ephemeris and at least three satellite signals; and associating the fourth location information with the fourth multimedia file.

16 . The device of claim 11 , wherein the processing unit is further configured at least for:
receiving over the wireless interface an auxiliary information from the external device that is one or a combination of a date information, a weather information, a temperature information, and an atmosphere pressure reading; and associating the multimedia file with the auxiliary information.

17 . The device of claim 11 further comprising a sensor, and the processing unit is further configured at least for:
receiving a sensor reading from one or a combination of a G-sensor, a barometer sensor, an atmosphere pressure sensor, a motion sensor, and a gyroscope sensor; and
associating the multimedia file with the sensor reading.

18 . The device of claim 11 , wherein the processing unit is configured for transmitting via the wireless interface the second signal to the external device in response to receiving the first signal comprising:
transmitting the second signal to the external device in response to receiving the first signal via the wireless interface which is a peer to peer (P2P) wireless interface, which is one of a Bluetoot
