OX03C10 is smallest ASIL-C automotive image sensor says OmniVision
Believed to be the industry’s first image sensor for automotive viewing cameras with 140dB high dynamic range (HDR) and LED flicker migration performance, the OX03C10 ASIL-C sensor provides low light sensing in premium vehicles.
The OX03C10 combines a large 3.0 micron pixel size with an HDR of 140dB and what OmniVision Technologies claims is the best LED flicker mitigation (LFM) performance for viewing applications with minimised motion artefacts.
It is claimed to be the first view sensor with HDR and LFM that can deliver 1920 x 1280p resolution at the highest rate of 60 frames per second, enabling greater design flexibility and faster camera-view switching for drivers. It is also claimed to have the lowest power consumption of any LFM image sensor with 2.5Mpixel resolution, which is 25 per cent lower than the nearest competitor says OmniVision, and the industry’s smallest package size.
Integrated basic image processing capabilities include defect pixel correction and lens correction. Integration of the HDR and LFM engine (HALE) combination algorithm provides optimal HDR and LFM performance simultaneously. The OX03C10 can be integrated into space constrained rear view cameras, surround view systems, camera monitoring systems and e-mirrors.
“The OX03C10 uses our Deep Well, dual conversion gain technology to provide significantly lower motion artefacts than the few competing sensors that offer 140dB HDR,” said Kavitha Ramane, staff automotive product marketing manager at OmniVision. The split-pixel LFM technology with four captures operates across the entire automotive temperature range, across all lighting conditions and in the presence of flickering LEDs from headlights, road signs and traffic signals, says the company.
OmniVision’s PureCel Plus-S stacked architecture enables pixel performance advantages over non-stacked technology. For example, 3D stacking allowed OmniVision to boost pixel and dark current performance, resulting in a 20 per cent improvement in the signal-to-noise ratio over the earlier generation of its 2.5Mpixel viewing sensors.
The OX03C10 also features four-lane MIPI CSI-2 and 12-bit DVP interfaces.
The image sensor is planned to be AEC-Q100 Grade 2 certified, and is available in both a-CSP and a-BGA packages.
