DUBLIN: A "fundamental" advance with image technology could lead to lenses that don't need filters and cameras that recharge themselves.

That's according to the US National Science Foundation (NSF), after Penn State University researchers announced recently they had come up with a device that produces photos by mimicking the human eye.
