Samsung Electronics has announced the first automotive image sensor named ISOCELL Auto4AC with the aim of expanding its presence beyond the smartphone sector. This sensor is used in reverse cameras and surround view monitors in automobiles and SUVs to deliver a high resolution feed (1280 x 960 resolution) to vehicle drivers. In addition, ISOCELL Auto 4AC with CornerPixel technology is said to make the driving experience safer by expanding the driver’s horizons.
Given the different lighting conditions on the road, the eyes take time to adapt to the occasional rapid transition from dim roads to bright settings. The new sensor stabilizes the lighting environment of the camera feed. For the first time, the company used CornerPixel technology to help reduce blind spots even in extreme situations. This technology has a special pixel structure that diffuses LED light above 90Hz. Two photodiodes, 3.0 µm pixels and 1.0 µm pixels, are embedded in one pixel area.
Photodiodes capture images with different exposures at the same time. The sensor allows for a smooth transition between dark and bright areas, minimizes motion blur, provides HDR up to 120 dB, and retains road details ahead. To minimize the flicker effect caused by the LED lights of other vehicles on the road, you can extend the exposure time of the small photodiode to prevent the pulsed LED lights from appearing as flicker on the dashcam screen. .. This provides the driver with a more comfortable viewing experience and provides more accurate image data of the LED-embedded object for recognition by the automotive system.
Duckhyun Chang, Executive Vice President of Sensors at Samsung Electronics, said of the sensor: “Starting with ISOCELL Auto 4AC, the lineup of automotive sensors includes camera monitor system (CMS), autonomous driving, and in-cabin monitoring.”
Since 4AC meets the AEC-Q100 Grade 2 standard, it has an operating temperature range of -40 ° C to 125 ° C and is in mass production.
