These four lenses are the horses for Huawei’s marketing carriage—and with good reason. It's quite a lineup:

40 MP ƒ/1.8 Cine Camera with a classical RGGB pattern on a 1/1.54" IMX608 sensor, outputting a 3:2 format

40 MP ƒ/1.6 SuperSensing Camera with Huawei’s special RYYB pattern and OIS on a 1/1.7" IMX600 sensor, shooting in 4:3

This camera can supposedly shoot 256× Ultra Slow-motion videos @7680 FPS, which might explain this little breakout board sitting in the middle of the data stream from the SuperSensing Camera. Is it a dedicated ISP (Image Signal Processor) for intensive slo-mo image buffering and calculation?

8 MP ƒ/2.4 telephoto lens with OIS over an OV08A10 sensor to offer 3x optical zoom, 5x hybrid zoom and up to 30x digital zoom

3D depth-sensing camera for real-time in-depth video effects with an IMX316 sensor

What remains on the motherboard seems to be the dot projector module that gives the 3D camera something to look at.
