Okay, I have this N810 and there's this application called Hike. It's a great idea - take a picture of a park map and calibrate it on the fly with the GPS. Amazing, wonderful idea, except the camera on the N810 produces pictures that are even smaller than the screen, near useless for viewing a map. Great app; no way to use it. Very frustrating.

So, lacking a camera that can send real photos to my N810 via bluetooth (they make them, but I'm not impressed with the camera-side spec's) I'm thinking that, maybe, I can get something better out of the N810's camera.

What I'm thinking is taking the video camera (in video mode) and grabbing a bunch of frames as the camera plays over a scene (like the park map) and then automatically stitching them together into one big image. In use, you would start the app, slowly pan the n810 camera over the target is some preset fashion, and then let the n810 chunk the results into a single large image.

I know, I could carry a couple of usb cables, and an adapter, and use a real camera, then transfer the image, or start swapping around micro-SDs and adaptors... but we're talking about going for a hike - it's a little cumbersome. Besides, there has to be some use for that N810 image sensor, besides taking pictures of your nose.

I know, I'm asking a lot, but has anyone heard of some Linux projects that might sorta work like that... video frame grabber to composite image stitcher? Something that is light enough for the N810 to maybe run? Has anyone managed to capture video from the sensor? If I can get the data out and a way to process the images, I'm not opposed to writing some Perl script to hack the two together.
