  3. Problems you were having?
    I am encountering difficulties with the camera’s performance in night vision mode, as it produces a prominent blue/purple tint. This tint is causing interference with my AI human detection algorithm.

Here are some images showing the purple tint:

I have tried the Arducam-477M.json and the default imx477-noir file

I am seeking guidance on how to address this issue and whether it is possible to modify the camera settings to render the night vision mode in black and white, which would be more compatible with my requirements.

Please help me with this issue
