The new device is simple in nature. “The architecture consists of two components, an aperture assembly and a sensor. No lens is used.”

The disadvantage, at least for the moment, is that it takes time to acquire the data for each image. So the camera only creates images of still scenes.

But even that is useful for surveillance since it is possible to compare consecutive images of the same scene to determine things that have changed or to work out the speed of moving objects.

Pictures never out of focus… Sounds like the future of photography to me.
