This new ISOCELL camera sensor takes advantage of CornerPixel technology, which places 3 micron photodiodes and 1 micron photodiodes in a single pixel. What these two photodiodes do is to capture images in different exposures at the same time, allowing for smoother transitions between poorly illuminated areas and bright ones while preserving more details of the road in front of the car.
Additionally, flickering from LED headlamps or traffic signals could become more visible on the video screen of the automobile system. To reduce LED flickering, the exposure period of the smaller photodiode can be increased, preventing pulsating LED light from appearing as flickering on the camera screen. This offers the driver a better viewing experience and the vehicle system more accurate image data on LED-embedded items to recognize.
It's not the first time when the South Korean tech company focuses on LED systems. A few months ago, Samsung has tested the automotive waters with PixCell LED, an LED module optimized for intelligent headlights, such as adaptive driving beam (ADB) systems.
But the ISOCELL Auto 4AC proves to be much more, offering LED flicker mitigation for surround-view monitors or rear-view cameras in HD 1280 x 960 resolution. Moreover, the ISOCELL camera sensor can operate between a temperature range of -40°C to 125°C (-40°F to 257°F) .
According to Samsung, this is only the first product out of a large line-up of automotive sensors, focused primarily on camera monitor systems, autonomous driving, and in-cabin monitoring. Currently, ISOCELL is in mass production and it is not yet known which cars will use the new sensor.
