Scientists in the US have developed a camera that sees things much like the human eye.
The researchers, from Northwestern University and the University of Illinois at Urbana-Champaign, claim that the curvilinear camera is even better than the human eye as it has zoom capabilities.
It is inexpensive to make but has 3.5x optical zoom, allowing it to take sharp images.
The creators believe that, once optimised, the technology will be useful in night-vision surveillance, robotic vision, endoscopic imaging and consumer electronics.
"We were inspired by the human eye, but we wanted to go beyond the human eye," said Yonggang Huang, a professor at Northwestern"s McCormick School of Engineering and Applied Science.
The research was published in the Proceedings of the National Academy of Sciences.
