| Samsung enters the field of car camera systems |
Samsung announced its entry into the car camera systems market with a sensor designed specifically for cars that uses unique technologies to adapt to low and bright light conditions.
Current cars are equipped with several cameras, including front and rear cameras, mirrors, side cameras, and driver monitoring cameras.
The world leader in advanced semiconductor technology introduced ISOCELL Auto 4AC, an image sensor for the automotive industry.
The sensor provides an extended high dynamic range of 120dB and flicker reduction for surround-view monitors or rear-view cameras at a high resolution of 1280 x 960 pixels.
The new ISOCELL Auto 4AC combines Samsung's innovative image sensor technology with CornerPixel's unique and advanced functional HDR and LFM solutions to deliver an excellent viewing experience in all lighting conditions.
“Starting with ISOCELL Auto 4AC, we plan to expand the vehicle sensor suite to include areas such as CMS camera monitoring system, autonomous driving and vehicle monitoring.”
Different lighting conditions on the road can present obstacles for the driver. A quick transition from a dimly lit environment to a bright one (such as exiting a tunnel) can take a few seconds for the driver's eyes to adjust.
Flashes of headlights or traffic lights increasingly appear on the vehicle's system camera display.

ISOCELL Auto 4AC provides drivers with a safer driving experience and better visibility thanks to CornerPixel technology. This technology uses a custom pixel architecture to suppress LED lighting above 90 Hz.
There are two photodiodes in one pixel area. The first has 3.0 micron pixels and is used to display images in low light. The second is 1 µm and is used in lighter environments.
The sensor can deliver HDR up to 120dB with reduced motion blur. Images of different exposures are simultaneously recorded in the presence of two photodiodes.
This allows for a smoother transition between dark and light areas while retaining more detail of the road ahead.
To reduce LED flicker, exposure time for smaller photodiodes can be extended. This will prevent the blinking LED light from appearing as a flash on the camera screen.
This provides the driver with a better visual experience and more accurate image data by incorporating objects into the LED for recognition by the vehicle's system.
