OmniVision Technologies, Inc., has announced the OV2312 automotive image sensor, which enables multiple functions in one camera. This multi-functional approach reduces total system cost, space and power budget for driver state monitoring (DSM) and viewing applications like video conferencing.
The ability to capture both RGB and IR images with one global shutter (GS) sensor reduces the number of cameras and total system cost. The OV2312 enables those dual-mode cameras with motion-artifact-free images at high resolutions of 1600×1300 at 60fps and 1280×720 at 90fps. Additionally, because this is the smallest 2MP GS sensor in its class—offered in a 7.2 x 6.1mm automotive chip-scale package—cameras can be placed out of sight from drivers and passengers.
For operation without visible light, the OV2312 features the 3.0-micron OmniPixel 3-GS architecture, which provides an industry-leading near-infrared quantum efficiency of 14% at the 940nm wavelength, along with excellent modulation transfer function (MTF). Not only does this sensor capture images with the high quality required for driver eye and gaze tracking when running in single mode at 60fps, it also reduces system power consumption and cost by using fewer IR LEDs. The sensor itself only consumes an industry-leading 190mW in typical conditions. This greatly reduces the heat generated, which further ensures optimal sensor performance for interior cameras that operate continuously in confined spaces.
To further ensure top DSM performance while minimizing power consumption, the OV2312 can be synchronized with the on/off pulses of the system’s IR light source. Additionally, its array size of 1600×1300 pixels is designed to fit the driver head box in a way that ensures reliable monitoring regardless of driver height, seat position or vehicle cockpit design.
OV2312 samples are available now, and it is AEC-Q100 Grade 2 certified for automotive applications.
