Housed in a compact 6.5×5.7-mm automotive chip-scale package (CSP), the OV2778 2-Mpixel image sensor from OmniVision enables unobtrusive camera placement for in-cabin monitoring. The 1080p sensor is based on the company’s 2.8-micron OmniBSI-2 Deep Well pixel technology, which leverages 65-nm design rules, a 300-mm wafer process, and backside illumination for enhanced image quality.

The OV2778 captures both RGB and infrared images in a single sensor. It can be used for such interior applications as detecting packages and unattended children, as well as videoconferencing. The device delivers 30 fps at full resolution and provides a 16-bit linear output from a single exposure. With the second exposure, the dynamic range increases to 120 dB, minimizing motion artifacts.

In addition to an integrated RGB-IR color filter, the OV2778 offers external frame synchronization and advanced ASIL functional safety. The image sensor is AEC-Q100 Grade 2 certified and operates over a temperature range of -40°C to +125°C. It consumes 395 mW when active and 10 mW in standby mode.
