There's quite a bit of research currently in progress to develop cameras
that do just that (Google for "Address Event Representation Camera") - I
remember a couple of my engineering friends did their honours thesis on
the topic.

AFAIK, the technology is better than regular CMOS imagers in terms of
power consumption, but tends to have a lower resolution and dynamic
range - good for embedded devices, not so good for photography. Also since
the time available for each frame needs to be bounded, you tend to get a
lot of pixels 'squashed' against either the upper or lower bound of the
intensity range.
