Camera model:

Hello, I tried to capture image at bright lighting condition (under bright sunlight). The image quality is normal if the exposure is set >=30 Usec. However, if I tried to lower the exposure further, the image becomes very noisy. May I know the possible reasons for this case?

The camera model is oak-D LR

Here is the code I used:

Hi HaoxuanTan ,
I believe we haven't yet added limit on min exposure. Is the image over-exposed at 30us?
Thanks, Erik

Hi Erik,

the image quality is good at 30us exposure. The image is not over-exposed as well.

Here is the image taken at 30us exposure.

Thanks, Haoxuan

Hi HaoxuanTan ,
That's great to hear, then we will limit the FW to 30us and that should fix the issue.
Thanks, Erik
