I'm not fully sure if I get the way how the IR cameras and emitters on Laptops work correctly. I expected however that the IR emitter is bright enough to light up my face sufficiently for face detection even in complete darkness. When running sudo howdy test however with only artificial lighting in my room I can only see the lights in my room. The rest is completely black. By putting a mirror in front of the camera I can confirm that the IR emitter is flashing. Also running https://github.com/EmixamPP/linux-enable-ir-emitter told me my IR emitter is already working fine.
Now is my expectation to be able to use face detection at low light wrong or do I need to fix the IR emitter?
My setup:
Linux Mint 21
howdy 2.6.1
Lenovo Yoga 16ACH6
