Samsung’s latest HDR image chip is designed for vehicle camera systems


The cars are charged with camera these days, including front and rear mirrors, side-view cameras and driver monitoring cameras. Samsung is trying to attack that market with a specially designed automotive sensor that uses a unique technology to adapt to both low and bright lighting situations, the company announced.

A smaller touch than the sensors used in the smartphone, the ISOCELL Auto 4AC offers a resolution of 1,280 x 960 but has a unique “CornerPixel” adjustment. Within a single pixel area it uses 1 micron and 3 micron photodiodes, with the latter used to capture images in low light situations. Much like Sony HDR Automotive Sensor, it can capture video at night, while also adapting to lighting situations that change quickly as in tunnels.


“With two photodiodes that capture images at different exposures simultaneously, the sensor offers up to 120dB HDR with minimal motion blur, allowing easier transitions between dark and bright areas while preserving more road detail,” according to Samsung. . At the same time, it can alleviate vibration issues with LED lights over 90 hertz used in headlights, street lamps and other sources.

Samsung reportedly won a $ 436 million contract to supply “the largest US manufacturer EV” with camera modules that would replace the rearview mirrors, according to Korea Economic Daily. This vehicle manufacturer is said to be Tesla and the vehicle may be the only one Cybertruck, which has cameras on the front protectors rather than rear mirrors, as well Elektrek has marked. All that said, however, the new sensor release may not be relevant and for now, the cameras still can not legally replace the side mirrors in the US

As with other automotive grade sensors, the ISOCELL Auto 4AC can withstand temperatures ranging from -40 to 125 degrees Celsius, and can be adapted to both human systems (mirrors, spare cameras, etc.) and mechanical systems ( self-directed). The sensor is currently in production, so it may appear in cars in the near future.
