White Balancing

Hi, I am trying to enable Auto White Balance to Auto for jetson nano with Arducam (IMX477) using the below GStreamer pipeline.

gst-launch-1.0 nvarguscamerasrc wbmode=1 awblock=true aelock=true ! nvvidconv ! xvimagesink

Setting wbmode=0 also makes no change.

Is there any way to set the ISO to 400 ?

Could someone please guide me through?

You can check what parameter can use for by “gst-inspect-1.0 nvarguscamerasrc”
How do you confirm the wbmode not working? You can try any others value like 9 to confirm it.

Hi @ShaneCCC ,

Thanks for the response.

There is no parameter in “gst-inspect-1.0 nvarguscamerasrc” to specify the ISO specification.

I run the pipeline with “gst-launch-1.0 nvarguscamerasrc wbmode=1 awblock=true aelock=true ! nvvidconv ! xvimagesink” commands to verify the change in the picture.

The image is also blue in color.

Then there’s no ISO but you can try gain and exposure for it.

Sure, will try that.

Can you provide any guidance for the white balance thing and why the images have a blue tint?

You may need have camera partner to help for the image tuning for this kind of problem.
