1. A method of appending a position stamp to an image file of a photo or video clip taken with a digital camera having a GPS antenna and a GPS RF front-end including an analogue to digital converter for receiving GPS signals and outputting GPS signal samples, the method comprising the steps of:
- (i) upon a user taking a photo or video clip;
(a) creating an image file containing that photo or video clip, and(b) sampling received GPS signals and storing those GPS signal samples with an indication of the image file of the photo or video clip to which those GPS signal samples pertain; and
(ii) subsequently processing the GPS signal samples to obtain a position fix and appending the position fix to the image file.

7. A digital camera comprising:
-
a GPS antenna; a GPS RF front-end including an analogue to digital converter for receiving GPS signals;
said digital camera being configured so that upon a user taking a photo or video clip;(a) an image file is created containing that photo or video clip and (b) received GPS signals are sampled and the GPS signal samples are stored with an indication of the created image file to which said GPS signal samples pertain; and a GPS signal processor to perform subsequent processing of the GPS signal samples to obtain a position fix and append the position fix to the image file. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A computer comprising a processor and receiver, and configured to:
-
(a) receive through the receiver an image file containing a photo or video clip, GPS signal samples and an indication of the corresponding image file to which the GPS signal samples pertain by virtue of having been sampled when the corresponding photo or video clip was taken; (b) process by operation of the processor the GPS signal samples to obtain a position fix; and (c) append the position fix to the corresponding image file by operation of the processor.
