Automotive Image Sensor for Cabin and Occupant Monitoring Applications

Posted Apr 10, 2019 by OmniVision Technologies

OmniVision Technologies has released a new automotive image sensor, OV2778, which provides the best value of any 2MP RGB-IR sensor for cabin and occupant monitoring in cars. With its complement of industry-leading features, the sensor is ideal for interior applications such as detecting packages and unattended children, as well as video conferencing.

The OV2778 comes in the smallest package available for the automotive in-cabin market segment—a 6.5 x 5.7mm automotive CSP—enabling the smallest camera sizes possible for unobtrusive placement inside the vehicle. It also offers advanced ASIL functional safety, which is important for in-cabin applications when the OV2778 is being integrated as part of an ADAS system.

According to Thilo Rausch, product marketing manager at OmniVision, demand for cabin and occupant monitoring are accelerating growth in the global automotive image sensor market. The new OV2778 image sensor enables these applications in mainstream vehicles by providing the best value with high sensitivity across all lighting conditions.

The image sensor is built on OmniVision's 2.8-micron OmniBSI-2 Deep Well pixel technology, which delivers a 16-bit linear output from a single exposure with best-in-class low-light sensitivity. With the second exposure, the dynamic range increases to 120dB, which minimizes motion artifacts. With leading low-light performance, this sensor is ideally suited for in-cabin applications. Additionally, with an integrated RGB-IR, 4x4 pattern color filter and external frame synchronization capability, the OV2778 yields top performance across varying lighting conditions.

The image sensor is AEC-Q100 Grade 2 certified for automotive applications. It also benefits from the large installed base of its predecessor, enabling it to be easily integrated into existing automotive platforms. OV2778 samples are available now, along with a plug-and-play automotive reference design system that can be connected to any vehicle for rapid development. The image sensor will be demonstrated at the Auto Shanghai trade show from April 18-20, by appointment only.
