Sony Unveils Automotive HDR Sensor with LED Flicker Reduction

PRNewswire: Sony announces a 2.45MP 1/2.7-inch CMOS sensor for automotive cameras, the IMX390CQV. Sony will begin shipping samples in May 2017.

The new image sensor features an LED flicker mitigation function that reduces flickering when shooting LED signs and traffic signals, as well as an HDR of 120dB (measured according to EMVA1288). The IMX390CQV is said to be the first in the industry that can simultaneously mitigate LED flicker and shoot in HDR, made possible by Sony's new pixel structure and exposure method. It also offers high-sensitivity down to 0.1 lux.

Sony publishes two Youtube videos demoing the LED flicker reduction and HDR features:






The IMX390CQV is planned to meet the requirements of the AEC-Q100 Grade 2 automotive electronic component reliability tests this fiscal year. Moreover, with this new product, Sony also introduced a development process that complies with ISO26262 automobile functional safety standards, aiming to achieve a high level of design quality for an automotive product. The new sensor also meets the functional safety requirement level ASIL C.


Thanks to DS for the pointer!

  1. what's the frame rate for the 0.1 lux image?

  2. I guess it's a rolling shutter sensor?

  3. It seems that the left picture dynamic range is dramatically reduced. In watching there is a vehicle even washed out by the sky, but not on the right video. That can't happen in ADAS. What happened to Sony?

  4. what happened is that the long exposure has to be long enough to ensure LEDs are not flickering. That is why the sky is very bright.
