SmartSens Releases LED Flicker Suppression Technology

Oct. 24, 2019—SmartSens, a supplier of high-performance CMOS imaging systems, recently announced the release of its proprietary LED Flicker Suppression (LFS) technology. 

SmartSens' CMOS image sensors can mitigate the dangers that often accompany LED flicker, making AI-enabled Advanced Driver-Assistance Systems (or ADAS) and autonomous vehicles much safer than before.

LED has gradually replaced traditional lighting options in various automotive applications – such as traffic lights, car headlamps and turn signals. However, since LED drivers often utilize Pulse Width Modulation (PWM) signals, LED lights actually "flicker" at frequencies imperceptible to the unaided eye. For CMOS image sensors that have even faster shutter speeds, mismatch between exposure time and LED pulse could lead to sensors picking up inaccurate visual signals.

Automotive CMOS image sensors must adapt to modern traffic signal systems by being able to distinguish between the on and off states of LEDs.
