hello sjg23ie,
actually, it’s an issue from camera hardware modules.
we’ve notice that IMX219 (raspberry Pi version) has unusually high noise level with bad pixels. you can also seen different noisy capture results on different IMX219 camera modules.
for example,
camera image quality tuning specific to each sensor modules, and it always an extra efforts.
there’re some explanations you may also check in discussion thread, Topic 139727. the attach binary adjust noise reduction tuning settings for Xavier NX/ IMX219.
we don’t provide image tuning support via forum discussion threads.
you may share your actual use-case and also the IQ expectation, please contact with nvidia sales team if you would like dedicated tuning supports.
thanks
