<50us timestamping allows accurate 3D tracking.

Optimized ISP for computer vision rather than photography. Cleaner RAW data, minimize noise & latency.

HW accelerated feature extraction and tracking (optical flow)

Sensor fusion of camera, gyro, and accelerometer data.

Recognizing the location of previously visited locations.

Vendor providedHW sensor/SW library.

Compute intensive 3D reconstruction algorithms (1st & 3rd party).
