The ISP tuning depends on the sensor and lens. So, probably the ISP configuration file that you downloaded is not compatible for the IMX219 model that you have. I actually tested this ISP configuration file using the basic IMX219 module and I don’t see this red tint.
I believe that ARDU cam website should specify that this calibration file may not work for all the available IMX219 camera modules. In your case it seems that you would need a specific ISP calibration for the model that you are using.
You can check this wiki for more information about the ISP calibration: Custom_ISP_Configuration
Thank you for your reply.
I’ve contacted ArduCam with this problem and I will keep this thread updated with the solution provided by them, in case someone else faces the same issue.
After contacting ArduCam support, they replied with the following:
Yes, the ISP tuning file is not fully adapted to the lens of this camera. Unfortunately, Nvidia has not opened the ISP tuning tool to us, so we cannot provide a fully suitable tuning file.
Therefore, I’ll try to contact NVIDIA to check if they have some solution to this.
