I love the creative use of the rolling shutter, instead of seeing it as a downside, they turned the line-by-line nature of the sensor into sample rate multiplier.

The use of rolling shutter to increase effective sampling rate was present in the original SIGGRAPH 2014 Davis et al paper from Bill Freeman’s group at MIT, “The Visual Microphone: Passive Recovery of Sound from Video” (https://dspace.mit.edu/handle/1721.1/100023).

The authors of the current paper cite this and other prior work. The key innovation is the use of both a rolling shutter and a global shutter reference.

That blew me away before I even finished the paper.
