On: Xiaomi explains more about how its under-screen camera works

[Someone]

The end game could be to have millions of low quality (possibly single-pixel) cameras in your screen, with software combining the images into a single one from a location that can be (somewhat) controlled in software.

IIRC, that’s what was proposed in Starfire, in 1992. (https://www.asktog.com/starfire/), where they could also use those tiny cameras as a scanner (place a paper on top of the screen, and read out all the pinhole cameras)

Put a full screen sensor under the screen and scan pinholes while also playing video.

Apple filed for patents on this circa 2001.

Which means we're only two years from them expiring.

Not sure when they were issued.
