PRNewswire: OmniVision announces the 1080p30 OV2775 built on 2.8um OmniBSI-2 Deep Well pixel technology, which delivers a 16-bit linear output from a single exposure with best-in-class low-light sensitivity. The OV2775 is aimed to automotive imaging applications, including next-generation ADAS, rear video mirrors, camera monitor systems (CMS), and dash cameras.

"The challenging imaging conditions in automotive applications require high dynamic range (HDR) images and fast motion capture, but unwanted effects that often accompany HDR images are not just cosmetic shortcomings — they are functional concerns," said Bahman Hadji, senior automotive marketing manager at OmniVision. "The OV2775's Deep Well™ pixel technology provides a linear 16-bit output to achieve 94dB dynamic range, compared to traditional sensors with only 12-bit linear output. This 94dB output comes without HDR combination artifacts and has no sudden drops in signal-to-noise ratio across the scene. When operating in dual-exposure mode, the sensor can further expand dynamic range to more than 120dB using a second 'very short' exposure to minimize motion artifacts."

The OV2775 comes in an AEC-Q100 Grade 2-qualified, compact 6.7 x 5.9 mm chip scale package. It contains an advanced set of features to enable ISO26262 ASIL B-rated camera systems. The sensor can be used with OmniVision's ISP companion chips (OV491 and OV495) for display-based automotive applications.

The OV2775 is currently available for sampling and is expected to enter volume production in Q2 2017.

As far as I can judge from the raw format description in the flyer, the Deep Well is a sort of combination of two 12b images, possibly with dual gain pixel or something similar:
