about image sensor calibration

Question

hello, 

I just run the PCAM demo project and noticed the white balance is off. I can see the AWBs working but the image has a green cast. Has someone experienced similar results or can this be improved changing my lightening environment? 

 

What would be the best approach to improve AWB? Does the sensor provide a calibration mechanism? I think I could load different colour matix'es to the sensor for different lighting scenarios. Is this a good solution?

Alternatively I can implement my own algorithm and configure it with manual white balance. 

 

What other factors could be involved in this behaviour, other than colour temperature? Judging from the colour (green) maybe gain/awb are not accounting for the bayer filter entirely? 

 

thank you
