I'm the one who asked about the Stanford University Frankencamera (fcam) project after your great talk at 38c3.
Link here: https://graphics.stanford.edu/papers/fcam/
It's pretty old now, but afaik, they were very early, if not the first, to do many of the computational photography stuff which now the norm in proprietary camera implementations.
They went to port the thing to the Nokia N900 which also was a Linux phone (no Android!). That's why I thought it sounds similar / related to what you're doing...
@vimja Yeah I had fcam installed on my N900 but I forgot it was called frankencamera :D
I still use the n900 btw. But I'm not sure if I should put effort into supporting it in libobscura :)
