    about image sensor calibration

    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
  2. Hi, I am a newbie...I am interested in buying Embedded Vision Bundle, but i have some technical concerns.I read on the datasheet of Zybo Z7-20 that the PCAM module is working (or preset) under the specific frame per second rate ( such as 30 or 60 fps) at the full resolution. ( in this given link below, the supported resolutions are given as * 1080p@30Hz* 720p@60Hz https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-z7-pcam-5c-demo/start ) I know that it is only a demo document, and i am hopping that with proper way i can get a higher frame rates at lower resolutions.My question that is it possible to have higher fps rates (i.e 1000 fps) at lower resolution (i.e 750fps 320x240 pixels).Thank you so much in advance,Regards,Sirac KAYAPollution Control Technologies
