We spent the first month of the project on the v2 modules. These are based on the Sony IMX219. Unlike the v1 cameras, the datasheets are publicly available and even then, after much hacking around we couldn't get all the lines to expose at the same time :'/

I would also like to know this.

It is not - from what I gather it's capturing a single exposure of a scene lit via a strobe to give a virtual 1/2000000s shutter speed.

Still super cool - the meat of what's novel here isn't the image assembly though, but rather the reverse engineering of the pi cams in a global shutter mode - I'm definitely interested in what the tradeoffs are around global vs. rolling shutter, if there's image artifacts or bandwidth issues, or what. Neat work gang!
