Arducam B0201 - IMX291 auto exposure in low light

USB UVC Webcams
1

Hi,

I have just bought this camera. It seems like the auto exposure range is limited to maintain high fps out. In low light, I have to manually increase the exposure. Some other manufacturers expose a “low light compensation” setting in UVC controls so auto exposure can increase up to 1-2fps. Can this feature be enabled on this camera?

 

Thanks.
