How to enable auto exposure on imx219

#1

I would like to use the full capabilities of the camera and the isp. So I need to have auto exposure function at least.

To day, I able to drive exposure and gains manually but I know that the ISP can do the job for me and better than me !

And ideally, i would like to tweak configuration of the ISP like AWB or denoise filter strength ?

With raspberry pi I know it is directly in the gst-launch command, I can access with the rpicamsrc to the isp configuration like “awb-mode” to be in “fluorescent” mode for example.

Any idea on how to do that ?

Hi @nicolas_HILAIRE,
The system has default to use the rkaiq service to automatically manage the camera exposure.

Hi,
I’m okay with that and the rkaiq service is started and use the right iqfile but exposure doesn’t change at all even on dark or bright environments. Maybe I miss something to enable auto exposure ?
