Abstract

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 together with a digital camera and computer for the same.

Claims

1. A method comprising:

(i) taking a photo or video clip using a digital camera;

(ii) creating an image file containing that photo or video clip;

(iii) sampling received GPS signals substantially simultaneously with the creation of said image file;

(iv) storing the received GPS signal samples with an indication of he image file of the photo or video clip to which GPS signal samples pertain; and

(v) subsequently processing the GPS signal samples to obtain a position fix resulting from said processing of the signal samples and appending the position fix to the image file.

2. A method according to claim 1 wherein step processing is done after a predetermined delay has elapsed after said storing.

3. A method according to claim 1 further comprising the uploading the image file and GPS signal samples to an external computer prior to said processing.

4. A method according to claim 1 further comprising detecting a connection to the camera of an external power source whereupon said processing is done either automatically or after user confirmation of an automatic prompt for the same.

5. A method according to claim 1 said taking, creating and sampling is performed a plurality of times, prior to said processing being done for the first photo or video clip.
