Camera now magenta after update

Sun Jul 14, 2019 12:10 pm

Did an update to a Raspberry PI 3B+ this morning and now all output of the camera module are magenta. With RPi Cam running, the video pulses that magenta colour.

Is this a noir camera? You might need to turn off the new AWB algorithm, we are currently tweaking that for noir.

Replaced the 2.1 module with an older 1.3 module which I am hoping is also Noir and it is working again. How do I turn off the now AWB algorithm?

I have the same problem, very pink/magenta colour especially evident in strong light changes which wont then recover! Is there a proper fix coming out for this problem?

If I stop the video (RPi Cam mjpeg) then it recovers.

Run
sudo rpi-update && sudo reboot
then rerest. There's supposed to be a AWB fix for NOIR cameras in the latest bootcode/firmware.

Thanks, that seems to have cured it. Will test more in next few days outside.
