GPS pre-acquisition for geotagging digital photos
First Claim
1. A method for a mobile electronic device comprising a digital camera, a position-determining subsystem, and a user interface, the method comprising:
- detecting, by the mobile device via the user interface, user activity with respect to the digital camera of the device; and
in response to detecting the user activity and prior to initiating capture of an image using the digital camera, initiating, by the position-determining subsystem of the mobile device, acquisition of current position data for a current position of the device.

Abstract
A handheld electronic device, such as a GPS-enabled wireless communications device with an embedded camera, a GPS-enabled camera-phone or a GPS-enabled digital camera, determines whether ephemeris data needs to be obtained for geotagging digital photos taken with the device. By monitoring user activity with respect to the camera, such as activation of the camera, the device can begin pre-acquisition of a GPS position fix by obtaining needed ephemeris data before the photograph is actually taken. This GPS pre-acquisition improves the likelihood that a position fix (GPS lock) is achieved by the time the photo is taken (to enable immediate geotagging). Alternatively, the photo can be geotagged retroactively by appending the current location to the metadata tag associated with the digital photo. An optional acquisition status indicator can be displayed on a user interface of the device to indicate that a position fix is being obtained.

44. A mobile electronic device comprising:
-
a digital camera for capturing an image; a user interface; a position-determining subsystem; and a processor that is configured to detect, via the user interface, user activity with respect to the digital camera and for causing the position-determining subsystem to initiate acquisition of current position data for a current position of the device in response to detecting the user activity and prior to initiating capture of the image using the digital camera. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)
