Newly developed "smart glass" technology that mimics the shutter capabilities of a traditional camera could improve the pictures you snap on your smartphone. Researchers in Germany have developed a camera component for smartphones that helps adjust light, exposure and focus.
Traditional cameras have what photographers refer to as an aperture — overlapping blades around the inside of a lens that move mechanically to change the size and focus of the lens. The aperture is sometimes referred to as an "iris." Much like the iris of the human eye, it controls how much light enters the mechanism, which affects the image that is eventually produced. When it comes to cameras, the amount of light that touches the camera's sensors affect the overall focus of the picture you take.
Because of their size, smartphone cameras currently don’t have aperture mechanisms. "There is no technology today that can realize an iris aperture for smartphone cameras," said Tobias Deutschmann, physicist at the Technische Universitaet Kaiserslautern in Germany and lead-author of the study.
