What do you mean by "image faster than light"?

How is an image not light?

Or do you mean a captured image may show items from different points in time?

But that's only relevant after the photo has been created, not during the window of time that a sensor is capturing light.

Stand a meter away from a wall and wave a laser pointer such that the spot travels back and forth between two points a meter apart in one second. Move two meters away, but keep your movement exactly the same; the spot now moves two meters in one second.

Move two light-seconds away and do the same movement. The spot now moves two light-seconds in one second: twice the speed of light. Of course it takes two seconds from when you turn the laser on to when an observer at the wall would see it, and four seconds before you see the spot on the wall, but the spot itself moves faster than light.

Ah, so for the sake of capturing conceptual / perceived "objects", the global shutter, at least, can do a better job at what would be perceived during a short period of time that the shutter opens and captures each pixel.

A rolling shutter might capture points along the way but leave gaps in comparison. In the laser pointer example, you'd probably want a longer exposure, but the global shutter would still give you uniform capture better matching what your eyes / brain perceived.
