BTW, another problem I have which I would love some help with: may I get the FW
commands for setting basic 3A parameters?

It seems like the default AE mode does frame-averaging, which is really
unsuitable for video calls on the webcam. My face is really underexposed as a
result during the daytime because there's a lot of ambient light in the
background.

The webcam on this laptop also has a very wide field of view, which makes my
face appear small and shows too much of the background. This also exacerbates
the AE problem.

I'm thinking CMD_ID_SET_ZOOM would fix the FOV problem, and then either
CMD_ID_AE_SET_MODE to change the AE mode or CMD_ID_AE_SET_REGION to set the AE
ROI would fix the exposure problem. What do you think?

Thanks,
