Sony announced it First High-Sensitivity CMOS Image Sensor for the Automotive Cameras, it simply delivering Simultaneous LED Flicker Mitigation as well as High-Quality HDR Shooting, it is one of the first designed specifically to help autonomous vehicles function in less-than-ideal conditions.
It’s a 2.45MP (effective) IMX390CQV type CMOS sensor which is said to be capable of handling different and changing lighting conditions better than other cameras meant for auto-driving cars.
The contrast in a street, at midnight can be more than a standard camera’s sensor can handle. Tunnels or Underpasses (with low light) are particularly tough on entry and exit because of the huge differences in lighting. In particular, Contrast between the large amount of illumination coming from a stoplight and the low amount of light on a street sign or emitted from a pedestrian wearing dark clothes can be extremely large. Sony claims its new sensor has 120dB dynamic range and low light sensitivity down to an amazing .1 lux, means that it should be able to capture the entire scene in each frame, which is same as for the light coming from the moon to us. This will prove to be helpful for those who might be riding a self-driving car during the night on a full-moon day with no other better source of light around.
The sensor boasts of featuring an LED flicker mitigation function which helps in reducing the LED flickering coming from LED signals and traffic signals. This sensor is also said to meet all quality standards required for automotive applications. The IMX390 CMOS Image Sensor will enter small production runs starting next month with a ship sometimes in March for the finalized version.
