Patent Images
1. A positioning system comprising:
- a first mobile device comprising;
a first wireless communication unit;
an imaging unit; and
a first processor to control the imaging unit to capture an image in response to a user operation, and to transmit a location request signal through the first wireless communication unit upon the imaging unit capturing the image; and
a second mobile device comprising;
a second wireless communication unit to communicate with the first wireless communication unit;
a location information obtaining unit to obtain current location information of the first mobile device; and
a second processor to receive the location request signal through the second wireless communication unit, to control the location information obtaining unit to obtain the location information of the first mobile device upon receiving the location request signal, and to transmit the location information through the second wireless communication unit after the location information obtaining unit obtains the location information of the first mobile device;
wherein the first processor receives the location information through the first wireless communication unit, and includes the location information in the image taken by the imaging unit upon receiving the location information;
wherein each of the images taken by the imaging unit comprises EXIF data, the location information is included in the EXIF data associated with the image.

Abstract
A positioning system includes a first mobile device and a second mobile device. The first mobile device includes a first wireless communication unit and an imaging unit. The second mobile device includes a second wireless communication unit and a location information obtaining unit. When an image is captured by the first mobile device, the first mobile device can communicate with the second mobile device to obtain position information, which is then included in EXIF of the just captured image.
