Sony Announces High-Sensitivity CMOS Image Sensor for Automotive Cameras
Sony today announced the commercialization of a new 2.45 effective megapixel CMOS image sensor for automotive cameras, the IMX390CQV type 1/2.7. Sony IMX390CQV type 1/2.7 image sensor is equipped with an LED flicker mitigation function that reduces flickering when shooting LED signs and traffic signals, as well as an HDR function capable of 120dB wide dynamic range shooting. Sony IMX390CQV is the first in the industry that can simultaneously mitigate LED flicker and shoot in HDR, a capability made possible by Sony’s original pixel structure and exposure method.
The new image sensor is equipped with circuits possessing improved efficiency when converting electronic signals received from photodiodes to voltage signals. This delivers the highest sensitivity, approximately 1.5x that of conventional*3 image sensors for 2.0 megapixel class automotive cameras (according to Sony research). This capability enables the sensor to capture high-quality color images even in light conditions as low as 0.1 lux, which is equivalent to moonlight, enhancing camera reliability in rendering obstacles and persons. Sony will begin shipping samples in May 2017.
