Smart Glasses Dim Bright Objects

These glasses can dim bright objects by restricting light in selective parts of the field of view.
The glasses feed the input from a camera through a small computer that “balances” the image by running an algorithm that dims the brightest areas.

Camera- and liquid-crystal display (LCD) -equipped smart glasses developed by scientists at Japan's Nara Institute of Science and Technology (NAIST) can "balance" a scene by dimming bright objects without affecting dim ones.
The glasses feed camera input through a computer running an algorithm that dims the brightest areas.
The LCD lenses can tune the amount of light passing through each pixel of the LCDs according to computer output.
The device can adjust to changing lighting conditions in 20 microseconds, enabling seamless-seeming transitions.
NAIST's Xiaodan Hu said, "The general public can use them while driving or cycling for added comfort and safety."
