Hi Community!
The i.MX8M Plus reference manual states that the camera's ISP has a filter function to reduce noise.
・Denoising pre-filter
・Filter (Noise reduction)
・Enhanced Chroma Noise Reduction (CNR)
I have a few questions.
Which register should I operate to turn on these filters?
What exactly are these filters? Are there any formulas for calculating the filters?
Thank you in advance for your help
Best Regards,
Hiroki

Hi @A_Hiroki,
I am afraid that the algos relevant to the ISP on iMX8MP are not open to public. You might need to ask the NXP FAE in your region.

Hi @A_Hiroki,
You can try the VVEXT tool from the isp-imx framework (found in /opt/imx8-isp/bin/ on a running board) and investigate the source code of relevant elements in the pipelines (sensor, isp, dwe, ...) here : https://github.com/nxp-imx/isp-vvcam
