Sony's clever image sensor helps autonomous cars see better

Sony has developed a CCD image sensor that can help autonomous cars make sense of electronic road signs and see better when transitioning between dark tunnels and daylight.The IMX390 sensor has an anti-flicker function that means images of LED road signs come out clear. As LED signs are often used to indicate temporary road conditions or changes in speed limits, it's important for an autonomous car to be able to recognize them.On a standard sensor, LED signs appear to flicker or have a stro
