Arducam B0201 – IMX291 auto exposure in low light

[shailen]

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.

Hello,

It should be supported. I have consulted the original factory about how to open it, waiting for my news.

Excellent thank you. I can flash, compile code etc. whatever is necessary to get this feature. Thanks.
