Shows an entire movie in a single image.



Can anyone explain how this works?


I don't know for sure, but judging from the sequence shots, looks like it scans a pixel column depending corresponding to the part of the movie. If it's scanning a frame halfway of the movie, it will scan the pixel column in the middle of the frame.


Basically, it's the equivalent of putting a monitor face down on a flatbed scanner, and scanning while the movie plays.

Or taking a photo of the screen with a very slow CMOS (camera phone) sensor.
