Image sensor tailored for the automotive industry with CornerPixel technology and high HDR

Samsung’s ISOCELL Auto 4AC is a viewing camera sensor for surround view monitors or rear-view cameras in HD resolution

The new automotive image sensor provides 120-decibel (dB) high dynamic range (HDR) and LED flicker mitigation (LFM) for surround-view monitors (SVM) or rear-view cameras (RVC) in high-definition resolution (1280 x 960).

The sensor use CornerPixel technology for advanced HDR and LFM capabilities, offering exceptional viewing experiences regardless of lighting conditions. Variations in lighting conditions on the road may pose obstacles to the driver. Quick transitions from a low-lit environment to a brighter one, such as exiting a tunnel, may require a few seconds for the driver’s eyes to adjust. Also, flickering from LED headlamps or road signage, such as street lamps and traffic lights, could become increasingly noticeable on the automotive system’s camera screen.

The ISOCELL Auto 4AC offers a safer driving experience with an enhanced field of view for the driver with its CornerPixel technology, featuring a pixel structure that mitigates LED light over 90-hertz (Hz). Within a single pixel area, it embeds two photodiodes, one 3.0µm pixel for viewing low light images, and a 1.0µm pixel placed at the corner of the big pixel for brighter environments. With two photodiodes capturing images in different exposures simultaneously, the sensor offers up to 120dB HDR with minimal motion blur, allowing smoother transitions between dark and bright areas while preserving more details of the road ahead.
