Perovskites are research materials being researched.

Images produced from SPECT cameras have been around for a while. [2]

This is potentially a 16 pixel "camera" which the "image" is a gaussian blob (Figure 1e and 5e) [1].

This is interesting for a variety of reasons but is way overblown in the "camera" or "image" context. It's demonstration that one can make pixelated devices (4x4) of a specific kind of promising material.
