OV7251¶
OMNIVISION’s OV7251 is a 480P global shutter grayscale image sensor. It’s used in OAK-D-Lite as the stereo camera pair.

FFC compatibility¶
With OAK FFC boards you can easily evaluate different sensors and optics, as you can connect FFC camera boards to any OAK FFC baseboard (OAK-FFC-4P, OAK-FFC-3P) via a flexible cable. FFC camera boards are carrier boards for the CCM (additional information below), so it can easily be connected to any OAK FFC baseboard. The following FFC camera boards contain this sensor:

Sensor CCMs¶
Compact camera modules (CCMs) can be integrated directly into a custom product. CCMs are used in the final camera product. CCMs vary in optics and FPC connector. The following CCMs have been built using this sensor:
Sunny style long FPC:
NFOV FF (PY013) - 86° DFOV, 73° HFOV, 58° VFOV, EFL: 1.24, F. NO: 2.0±5%, Lens Size: 1/7” - on all OAK-D-Lite cameras
Arducam short FPC:
WFOV FF (PY030) - 166° DFOV, 163° HFOV, 157° VFOV, EFL: 0.83, F. NO: 2.0±5%, Lens Size: 1/7.5”
Sensor driver¶
Sensor driver adds support for that sensor to the Robotics Vision Core (RVC). Here are RVC2 driver specifications for this sensor:
Min exposure times:
Manual: 7 us (microseconds)
Auto-Exposure: 20 us
Min FPS: 0.8
Max exposure times:
Manual: 1 / CAM_FPS (eg. 33ms @ 30FPS)
Auto-Exposure:
AntiBanding OFF: 33ms
AntiBanding 50Hz: 30ms
AntiBanding 60Hz: 25ms
Max AE exposure time depends on the Anti-Banding (AB) mode, which helps to avoid flickering when using artificial lighting. We can configure the AB using the API:
cam = pipeline.create(dai.node.MonoCamera) # Or ColorCamera
# "OFF", "MAINS_50_HZ", or "MAINS_60_HZ"
cam.initialControl.setAntiBandingMode(dai.CameraControl.AntiBandingMode.OFF)
