A sensor that mimics the way a human eye responds to light could make digital cameras more efficient. This could pave the way to faster, more efficient machine vision for things like self-driving cars and robots.
Some modern cameras are built around charge-coupled devices (CCDs), which produce a voltage when light falls on them. Continuous light produces a continuous signal. By contrast, retinal cells produce a spike only when first lit up, reacting further only when the light changes. The biological system is more efficient in handling information, as it only sends new data.
