Gps pre-acquisition for geotagging digital photos

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