AMG8833 is an actual thermal sensor array, not an e.g. 8x8 photodiode array with IR sensitivity. It's of thermopile type, and different from microbolometer type like FLIR cameras(which has to go blank periodically, unlike themopiles that need not to).
Mouse sensors are 8x8ish cameras, but very few of them(basically only the genuine HP/Agilent/Avago ADNS-2610 at bottom tier price) has raw image export feature, for some reason.
There are many other tiny potato camera parts on various markets, but most of them are missing datasheet && require complicated interfacing.
Overall it's actually not so trivial to get a small image sensor for hobby experiments.
