Description:
When streaming live video from the OX05B1S camera on the FRDM i.MX95, some of the eyeglasses exhibit a dark blue/purple glare spot under indoor office lighting (see attached images).
How can we resolve this dark blue/purple glare artifact on reflective surfaces (like glasses)? What are the recommended Neo ISP tuning parameters or tuning tool version available for i.MX95 to fix this?
Hi @JosephAtNXP,
Thank you for the quick response and the insights regarding the lens flare, tone mapping, and black level configurations.
We do not currently use a third party for ISP tuning. We are using the tuning file provided by NXP for the OX05B1S sensor, which we found located at /usr/share/libcamera/ipa/nxp/neo/ox05b1s.yaml in our BSP.
Is it possible for NXP to provide a newly updated tuning file for the OX05B1S that mitigates this specific lighting artifact?
If an updated file isn't available, could you guide us on the exact parameter changes we should manually adjust in our existing ox05b1s.yaml file to fix this issue?
Looking forward to your guidance.
Regards,
Akash H
Hi,
Thank you for your interest in NXP Semiconductor products,
From the attached image, the dark spots seem like lens flares captured from a specific angle and reflected probably by blue light filters in your glasses.
Dark tones might be product of ISP tone mapping or black level configs. I would suggest ISP tuning the sensor,
In your projects, are sensors tuned by you or third parties?
Regards
