Wonder how they going to solve the problem with LED lights like At traffic lights with they cameras in car .Camera rate is at 60 fps I believe also to 120-240-360 fps   LED lights actually flicker but we don’t see it through our eyes so if a traffic light   Ok Sony found the solution.
Technical Features
Original design that does not saturate even after long exposure
The LED light sources used in traffic lights and signs, etc., are repeatedly turning ON and OFF at a frequency that cannot be detected by human eyes. When this is imaged with an image sensor, if the exposure time is shorter than this ON/OFF timing, then the image may be taken during the time when it is OFF, so it will not be possible to capture the LED light emission. There is also a risk that this leads to the lit state being mistakenly recognized as a flashing state.
Then the Automonouse vehicle doesn’t know if to stop or proceed
Using an exposure time longer than the emission period makes it possible to capture an LED light source, but there is the problem that a pixel can become saturated in some situations and blowout may occur. On that point, steps have been taken on the Sony Semiconductor Solutions Corporation's automotive image sensors to ensure that pixel saturation will not occur even if the exposure time is longer than the LED emission period. This makes it possible to capture the LED light source each period to acquire a high quality image signal with no flicker.
