"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:
