OV9782 pink colour

Looking at this post: https://discuss.luxonis.com/blog/1302-ov9782-lens-color-filtering-enhancement

I was wondering if the IMX378 Fixed-Focus instead of the OV9782 could solve the problem with the pink color?
Currently I have two cameras and want to use depth. So the given fix could not help me

Hi @dieter
Could you post an image of the lens coloring you are getting? I would advise against using IMX378 for stereo since rolling shutter isn't the best in stereo setups.

Thanks,

Hi jakaskerl

Thanks for the advise! Here an example picture. Could certain camera settings help?

For me the pink haze is not uniform, so do not think it is a IR filter problem. When I compare it to the IMX378, I notice that the colours are better, however this gives me motion blur. So maybe it is due to the sensor. The OV9782 has a bayer filter. Maybe that is what is causing the problem? What do you think? @jakaskerl

Hi @dieter
That's what I was checking. The IMX is rolling shutter which is worse for high speed or accuracy applications. It could also just be due to too high exposure time.

Thoughts?
