Well, how about this approach: http://talk.maemo.org/showthread.php?t=30387 Basically, rather than doing "in camera stitching" it would just grab video frames and auto-assemble them into a big picture. Getting that to run on hand-held devices would blow away any megapixel ratings. The resulting picture would be as big as you want, irrespective of any sensor limitation. Of course, it would only work on static scenes. I was interested in the N810, but the process should be able to support multiple devices. Also, there's not too much difference between generating a flat verses 360 panorama. There is software available that does stitch video frames to a single image, so it's just a matter of getting that to run under a Maemo device, getting the data from the video camera in the first place, and getting that data run through the app. I've no idea if it's possible for something like an N810 to run this much data crunching, at least in a reasonable amount of time, but at least there's a known process Quoting my original post here:
